A Note on Format<br />
Most <strong>safety</strong> <strong>manual</strong>s I have read enumerate the <strong>safety</strong> rules for each machine directly<br />
following the illustration and/or brief description of the machine and its uses. Usually<br />
embedded in these <strong>safety</strong> rules are bits of information that have little to do directly with<br />
the safe operation of the machine, but rather are methods of operation or information on<br />
maintenance. Potential hazards of each machine are scattered among these rules, and so<br />
are left to be gleaned by the reader. For this <strong>manual</strong> I have chosen to list the potential<br />
hazards posed by the machine, and their mitigations, immediately after the illustration<br />
and description of the machine, so that they will be readily apparent to the reader. I have<br />
also placed the methods of operation into a separate list following the <strong>safety</strong> rules.<br />
Disclaimer<br />
The information contained herein is believed to be true and correct. However, the author<br />

Introduction<br />
Hand tools and power-driven machine tools have been developed to save time and<br />
perform accurate, repeatable work. Hand and power tools will consistently perform the<br />
same operation hundreds of times if they are properly used, cared for, and understood. In<br />
nearly all cases, mistakes and/or injuries are due to operator error, not the machine.<br />
Whether the tools are helpful or harmful depends on you.<br />
These rules and operating instructions are for the protection of the students enrolled in the<br />
wood technology program. Complete familiarity with these rules is an essential<br />
component of safe and efficient woodworking. Students therefore will be required to pass<br />
a <strong>safety</strong> examination before being allowed to operate any machines.<br />
Industrial studies have shown that there are three desirable characteristics that a good and<br />
<strong>safety</strong> conscious worker possesses:<br />
1. He or she must be well informed regarding hazards.<br />
2. He or she must have developed proper and safe skills.<br />
3. He or she must have developed and must maintain good attitudes relating to<br />
his or her job and to safe practices within that job.<br />
The key words to remember are:<br />
KNOWLEDGE SKILL ATTITUDE<br />
Additionally, a study made by the National Safety Council on school lab accidents show<br />
that more accidents happen Saturday before noon than any other time and day of the<br />
week, except days just before or following vacations. Of course, this does not mean you<br />
can relax your <strong>safety</strong> habits during other days. In addition, the most dangerous school lab<br />
is the wood shop. In the wood shop, the tools that are involved in most accidents are<br />

GENERAL SAFETY RULES<br />
Note that the term “instructor” in this <strong>manual</strong> means the class instructor or the<br />
instructional aide. The term “margin of <strong>safety</strong>” refers to the minimum distance that<br />
the operator’s hands and fingers should be from the cutter, blade, bit, etc.<br />
1. In any level of the woodworking program, you are under no obligation to use<br />
power tools or machinery. Hand tool operations can be substituted for any and/or<br />
all machine operations.<br />
2. The use of cell phones and iPods (and the like) are strictly forbidden in the shop.<br />
3. It is good <strong>safety</strong> practice to be courteous and considerate of others.<br />
4. Hang nothing on fire extinguishers. The area around them should be kept clear so that<br />
they may be reached without delay if fire breaks out.<br />
5. Get instructor’s approval for all work you plan to do.<br />
6. Avoid long sleeves, loose clothing, neckties, long hair, or anything that can be caught<br />
up in moving machinery.<br />
5
7. Articles of jewelry, such as rings, necklaces and bracelets should be avoided. These<br />
items can get caught in moving machinery.<br />
8. Long, loose hair can easily be caught in revolving machinery and ripped out, causing<br />
serious scalp laceration. Your hair must be tied back or tightly covered when working<br />
with machines.<br />
9. Wearing gloves is forbidden while working with machines within the wood shop.<br />
Gloves hinder your dexterity and may get caught in moving machinery.<br />
10. If you feel ill, or are on any medication or any other substance that may affect your<br />
ability to operate machinery, report to your instructor.<br />
11. Report all injuries, even though slight, immediately to the instructor.<br />
12. RUNNING, PUSHING, YELLING, SHOVING, THROWING OF OBJECTS, OR<br />
ANY FORM OF HORSEPLAY IS VERY DANGEROUS AND IS STRICTLY<br />
FORBIDDEN. Students caught doing so will be given a referral and lose machine<br />
privileges.<br />
13. State law requires that whenever anyone is working in the shop, Safety glasses must be<br />
worn by everyone. If you have prescription eyeglasses, wear them; eyestrain is a<br />
frequent cause of accidents. Safety glasses that fit over your prescription glasses are<br />
available (OSHA approved Z87).<br />
14. Cooperate with your classmates in the student management of the room and equipment.<br />
15. Caution anyone you see violating a <strong>safety</strong> rule. Notify the instructor. You may save<br />
yourself or someone else from serious injury.<br />
16. Keep all vises closed and in the “in” position when not in use.<br />
17. Always carry long objects, such as metal rods and long boards, with the front end high<br />
enough to avoid striking someone.<br />
18. Remove all scrap and waste wood immediately from the floor where it may be a hazard<br />
to others. Put all waste wood in the scrap barrel.<br />
19. Floors, aisles, and passageways should be kept clear of pieces of wood, tools, and<br />
materials. Objects on the floor may cause someone to slip or fall.<br />
20. Always sweep scraps from your workbench or table with a brush or piece of wood<br />
rather than with your hands, as there may be sharp or jagged particles among the scraps.<br />
21. If you see oil, grease, or any other liquid on the floor, wipe it up immediately and report<br />
it to the instructor; you may prevent someone from slipping.<br />
22. Report to your instructor any odor of gas in the room. Gas fumes may make you ill or<br />
cause an explosion.<br />
23. Keep all combustible material in the covered metal container. Rags that have absorbed<br />
any amount of oil, linseed oil, gasoline, alcohol, shellac, paint, varnish or lacquer must<br />
be disposed of in an approved covered metal container as a precaution against<br />
spontaneous combustion.<br />
24. Do not lift anything in the shop that is too heavy for you; seek help. We will either use<br />
more personnel or employ mechanical help such as a lever, dolly, jack, forklift, wheels,<br />
or rollers.<br />
25. When lifting, keep your back straight and lift with your legs. Do not strain yourself;<br />
injury can occur easily.<br />
26. Use of compressed air hoses is permitted only under the supervision of the instructor.<br />
6
27. When using air under pressure, be sure the air stream is not directed toward you or any<br />
other person.<br />
HAND TOOLS<br />
28. Hardened tool surfaces (such as hammer heads) must never be struck together as the<br />
metal may chip sending off a red-hot particle.<br />
29. Sharp tools are safest: use them whenever possible. Dull tools are dangerous because<br />
they are hard to control and require excess pressure by the operator.<br />
30. Sharp or pointed tools must never be carried in the pockets. Always carry with points<br />
down. Always hand to another person handle first.<br />
31. All portable electric tools and appliances must be disconnected when not in use, making<br />
adjustments, when inserting cutters or bits, or when changing sandpaper.<br />
32. When unplugging an electric tool, pull on the plug instead of the cord.<br />
33. Be sure your hands are dry before touching electrical switches, plugs, or receptacles. If<br />
your hands are wet, you may receive a severe shock and serious burns.<br />
34. Use the proper tool for the job.<br />
MATERIALS<br />
35. Use only material furnished or approved by your instructor.<br />
36. Be sure that lumber is free from fasteners, checks, sand, paint, or loose knots before<br />
being machined. No used lumber may be run on any machine.<br />
37. Do not use green or treated lumber in any milling process.<br />
38. Lumber size restrictions for each machine must be strictly followed.<br />
MACHINES<br />
39. Students must be instructed in the correct and safe use of any machine before work can<br />
be done using that machine.<br />
40. All machine <strong>safety</strong> devices must be used. Any operation requiring the removal of a<br />
guard must be done by the instructor or under his or her personal supervision.<br />
41. All adjustments to machines must be done while the machine is at a complete stop.<br />
42. All special set ups must be inspected by the instructor before power is turned on.<br />
43. All wrenches and other tools must be removed from machines before power is turned<br />
on.<br />
44. Keep rags away from machines that are in operation.<br />
45. All students, except the operator, must stay outside the yellow <strong>safety</strong> zones on the floor.<br />
Where there are no yellow <strong>safety</strong> zones, students must observe the operator <strong>safety</strong> zone<br />
rule: one arm’s length away from student operating the machine.<br />
46. With the exception of instructor-approved special set-ups, only the operator may start<br />
and stop a machine. After the machine is turned off, he or she should control the<br />
material and stand by until the machine has stopped running.<br />
47. Do not attempt to distract any student using a machine. Do not let yourself be distracted<br />
when operating a machine. Wait until you are finished with the operation and shut down<br />
the machine before responding.<br />
7
48. Immediately report to the instructor any machine out of adjustment or that sounds<br />
unusual.<br />
49. Stock must never be forced into a machine faster than the machine will cut. Use a<br />
moderate feed rate.<br />
50. Only one person at a time is permitted to use a machine unless an instructor appointed<br />
helper is required because of the nature of the work. Students ripping lumber on the<br />
table saw will always require the assistance of someone to “tail off”.<br />
51. Never remove chips, shavings, scraps etc. from a machine while it is running. Stop the<br />
machine completely before doing so.<br />
52. The following tools are never to be used by students without direct instructor<br />
supervision: Portable circular saw, chain saw, any CNC equipment, and wide belt<br />
sander.<br />
53. If you are in doubt about the use of any tool or machine, or about any shop<br />
procedure, ask your instructor for help.<br />

Band Saw 20”<br />
The band saw is one<br />
of the most versatile<br />
machines in the shop.<br />
It is used for making<br />
curved cuts, for<br />
crosscutting with a<br />
miter gauge, ripping<br />
with a fence, resawing<br />
(slicing boards<br />
down their center to<br />
make them thinner),<br />
and free-hand cutting<br />
(without the use of a<br />
miter gauge or fence).<br />
The blade, a<br />
continuous band with<br />
teeth shaped into one<br />
edge, travels in a<br />
downward direction at<br />
the point of the cut as<br />
it tracks around two<br />
wheels, one above the<br />
table, and the other<br />
below. It is the<br />
diameter of these<br />
wheels that<br />
determines the size of<br />
the band saw. Blade<br />
width, typically ¼” to<br />
½”, dictates how tight<br />
a radius the saw will<br />
cut.<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection)<br />
• Getting hair/clothing caught in the blade (Tie hair back, no loose clothing)<br />
• Being cut by the blade either when it is turning or stationary (Be aware of surroundings,<br />
keep fingers away from blade)<br />
• Blade bending and snapping (simplify complex curves, make relief cuts)<br />
9
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the band saw.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers a safe distance from the saw blade. Always maintain a 4” margin of <strong>safety</strong>.<br />
Use push sticks when necessary.<br />
7. Feed material into the machine at a moderate rate of speed.<br />
8. Be sure all guards are in place.<br />
9. Never allow your hands to cross the line of cut.<br />
10. Set upper saw guide ¼” or less above the stock to be cut.<br />
11. Cut only stock that has a flat surface that rests securely on the table.<br />
12. Hold work or material firmly.<br />
13. Students should not change the saw blade or make any adjustments affecting the tracking<br />
of the blade.<br />
14. Report any mechanical defects or broken blade immediately to the instructor. A rhythmic<br />
click may mean a cracked or bent blade. Stop saw immediately and report to the<br />
instructor.<br />
15. No tilted table work should be done except under direct supervision of the instructor.<br />
16. Keep saw blade from twisting or binding when cutting curves.<br />
17. Machine must be at a complete stop before backing out of a cut to avoid pulling the blade<br />
off the wheels. Band saw has a foot brake (this may vary with different band saws).<br />
18. Keep waste from accumulating on the saw table. Machine should be at a stop when<br />
clearing scraps.<br />
19. Step away immediately if saw blade breaks or comes off wheels. Shut off power, if<br />
possible, without endangering self.<br />
20. Be sure the saw is completely stopped before walking away from it.<br />
21. All special set-ups need to be approved by the instructor.<br />
22. Do not attempt to cut cylindrical stock on the band saw.<br />
Methods of Operation:<br />
1. Allow saw to reach full speed before starting a cut.<br />
2. Plan sawing procedure so there may be a maximum forward feed with a minimum of<br />
backing out.<br />
3. Make relief cuts when necessary to cut a tight radius.<br />
4. Use “vee” block when cutting dowel.<br />
5. Clean band saw with a bench brush.<br />
10
Doweling (Horizontal Boring) Machine<br />
The Doweling Machine is used to<br />
accurately and consistently drill holes<br />
horizontally into the edges or ends of<br />
stock in preparation for accepting<br />
dowels for assembly. It consists of a<br />
table onto which the work is secured for<br />
drilling, a motor, which turns the drill<br />
bit, and a mechanism for feeding the<br />
drill bit into the stock. The brad point<br />
style drill bits vary is size from ¼” to<br />
½” in diameter, and are specialized with<br />
threaded ends so that they screw into the<br />
chuck of the machine. It is operated by<br />
securing the work with the cam style<br />
hold-down and feeding the bit into the<br />
work with the feed lever or foot pedal<br />
(some machines have pneumatic holddowns<br />
and power feed mechanisms).<br />
Setting a stop at the appropriate depth<br />
controls depth of the hole.<br />
Potential Hazards (and their Mitigation):<br />
• Injuring hand or fingers with the drill bit (Keep hands and fingers away from drill)<br />
• Catching of hair and clothing on rotating parts (Wear appropriate clothing; keep hair tied<br />
back)<br />
• Dust/debris in eyes (Wear eye protection)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the doweling machine.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
11
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers away from drill bit during operation.<br />
7. Feed drill bit into work, using foot pedal or handle, at a moderate rate of speed. Do not<br />
cause machine to slow down.<br />
8. Check bit to be sure it is properly fastened.<br />
9. Hold down must be adjusted so cam lock holds stock from moving during boring.<br />
10. Never use your finger to brush chips away from the reference line. Use a brush or blow it<br />
off.<br />
11. Make sure your hands are clear before engaging the foot pedal or feed lever.<br />
12. When finished operating doweling machine, turn off power and stand by until machine<br />
has stopped.<br />
Methods of Operation:<br />
1. Table must be adjusted so drill bit will enter wood at the proper place, usually in the<br />
middle of its thickness.<br />
2. Depth of cut must be adjusted prior to boring holes.<br />
3. Be sure drill bit size is correct for the dowels being used. All bit changes must be<br />
approved by the instructor.<br />
4. Clean doweling machine with a bench brush.<br />
12
Drill Press 18”<br />
The drill press is used primarily for drilling and<br />
boring holes in a controlled manner in a variety of<br />
materials. It can accommodate several bit types,<br />
from the common twist drill bit to hole saws and<br />
multi-spur bits. In addition to drilling, the drill<br />
press can be used for a variety of other operations<br />
including drum sanding, plug cutting, rotary<br />
rasping, buffing and polishing, to name a few. It<br />
consists of a column-mounted table to hold the<br />
work, a motor which drives the spindle, a chuck<br />
which holds the bit, and a base which secures it to<br />
the floor. The table is adjustable up and down the<br />
column by means of a crank on the right side of the<br />
table. In order for the table to move, the clamp on<br />
the left side on the table should be loosened.<br />
Potential Hazards (and their Mitigation):<br />
• Wood seized by bit and spinning (clamp wood to table or use drill press vise)<br />
• Fingers damaged by drill if holding a piece that is too small (use the drill press vise)<br />
• Hair/clothing caught in the spindle or bit (tie hair back, no loose clothing)<br />
• Wood chips flying into eyes (wear eye protection)<br />
• Fingers injured or severed by chuck key on chain (remove chuck key from chain)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the drill press.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
13
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Operate feed handle so that drill cuts evenly into work.<br />
7. Keep hands away from revolving spindle, chuck, etc.<br />
8. Tighten drill bit in chuck and remove chuck key immediately from chuck afterwards.<br />
Failure to do so could result in the key being thrown from the chuck.<br />
9. Use drill press vise or other clamping devices whenever working with small pieces.<br />
10. Work must be secured to the table with a clamping device when using a large bit. Failure<br />
to do so could cause the piece to be seized by the bit and spun around.<br />
11. The procedure for changing the spindle speed varies with each drill press type. Check<br />
with your instructor before attempting to change the speed.<br />
12. Be certain that the table of the drill press and the bit are secure.<br />
13. Select the proper drill bit for the job and avoid dull bits (see instructor if a bit is dull).<br />
14. Use the proper speed for the drill bit being used: Large Bits, Slow Speed; Small Bits,<br />
High Speed.<br />
15. Turn off power after using drill press and stand by until the machine has stopped before<br />
removing your work.<br />
16. Hold feed lever and work against table if it is seized by drill. Shut off power.<br />
Methods of Operation:<br />
1. Always place a wood support between table and project when drilling or boring. When<br />
drilling all the way through your work, to insure a clean exit hole, place your work<br />
over an un-drilled portion of the support block.<br />
2. When drilling to a specific depth, use the depth stop (depth stops vary on different<br />
machines).<br />
3. Ease up on feed handle when drill begins to break through material.<br />
4. Back drill out often to clear waste wood from the hole, especially when using multispur<br />
type drill bits.<br />
5. Clean off drill press table and surrounding area with bench brush and broom. Return<br />
cleaned drills, vise, sanding drums, plug cutter, etc. to designated place.<br />
6. Be sure to loosen the clamping device before attempting to raise or lower the table. Retighten<br />
the clamp to secure the table before drilling.<br />
14
Edge Sander 6” x 128”<br />
The Edge Sander is a machine that is designed to accurately sand the edges of stock, face frames,<br />
or glue-ups. It utilizes a 6” wide abrasive belt, which oscillates in an up and down motion to help<br />
distribute the heat build-up due to friction. Care must be taken when using the edge sander as it<br />
generates a considerable amount of friction and will take control of the work if it is not held<br />
securely. Edge sanders are capable of sanding with many different grits of abrasives.<br />
Potential Hazards (and their Mitigation):<br />
• Clothing getting caught by belt (no long sleeve clothing)<br />
• Sanding fingers or hands (keep hands away from abrasive belt)<br />
• Wood seized by abrasive belt, flies out of hands (hold work securely; rest work against<br />
fence)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the edge sander.<br />

3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep hands and fingers well away from abrasive belt; maintain a 4” margin of <strong>safety</strong>.<br />
7. Feed material into the belt deliberately and cautiously. Belt can easily seize the wood<br />
from your hand and cause a kickback.<br />
8. Keep guards in place.<br />
9. Edge sander is for sanding edge grain only, never face or end grain.<br />
10. If any breaks, tears, or looseness in the belt or loose parts are noticed, do not start the<br />
machine. Immediately notify the instructor.<br />
11. Minimum length for sanding is 12” unless approved by the instructor.<br />
12. Do not attempt to sand small pieces on the edge sander. The abrasive can easily injure<br />
your fingers.<br />
13. Hold work securely to avoid kick-back; hold work against fence if hands cannot control<br />
piece.<br />
14. Sand work lightly as abrasive generates a lot of friction and can take control of work.<br />
15. Keep dust collector vent open when in use.<br />
16. Turn off power and stand by until machine completely stops before leaving it.<br />
Methods of Operation:<br />
1. Move work from right to left, against direction of belt travel.<br />
2. With instructor’s approval, guards may be opened to accommodate longer stock.<br />
3. Table may be raised or lowered to take advantage of fresh abrasive on the belt.<br />
4. Clean edge sander with a bench brush.<br />
16
Jointer (Surfacer) 16”<br />
The Jointer, or Surfacer, is<br />
used to flatten the face of a<br />
board, straighten the edge of<br />
a board in preparation for<br />
joining it to another board<br />
(hence its name), rabbeting,<br />
beveling, and tapering. Its<br />
size is determined by the<br />
width of its cutterhead (and<br />
therefore the length of its<br />
cutters or knives) which<br />
indicates the widest board<br />
that can be surfaced. The<br />
jointer is operated by<br />
moving stock across the<br />
rapidly rotating knives from<br />
the infeed table to the outfeed table. Extreme caution must be exercised when using the jointer as<br />
its knives become exposed during operation. There is also the potential for kickback. Push blocks<br />
and push sticks must be used to keep the hands and fingers away from the cutters.<br />
17
Potential Hazards (and Their Mitigations):<br />
• Hand/finger contact with cutterhead (keep hands/fingers at least 4” from cutterhead, use<br />
push sticks, push block, be sure guard is functioning)<br />
• Clothing or jewelry caught in rotating cutterhead (avoid loose clothing or hanging<br />
jewelry)<br />
• Kick-back of work piece (observe minimum sizes, limit cut to 1/16” or less, use push<br />
block)<br />
• Wood chips/dust thrown at operator (wear eye protection)<br />
• Slipping and falling into cutterhead (balanced stance, no scraps on floor)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the jointer.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers a safe distance from the cutter head. Always maintain a 4” margin of <strong>safety</strong>.<br />
Use push sticks when necessary.<br />
7. Feed material into the machine at a moderate rate of speed.<br />
8. Be sure the cutterhead guard is in place and functioning.<br />
9. Jointer must be running at full speed before jointing stock.<br />
10. Limit depth of cut to 1/16” or less. Most cuts should be done at 1/32”.<br />
11. To avoid kickback, use only stock 12” or longer on the jointer.<br />
12. Check to be sure the fence is secure.<br />
13. Use only clean lumber, free of fasteners, checks, loose knots, sand, and paint.<br />
14. All special set-ups must be checked and approved by the instructor.<br />
15. Long pieces of stock need to be supported by a person tailing off.<br />
16. Push block must be used when jointing the face of a board; push sticks must be used<br />
when jointing the edge of stock under 4” wide.<br />
17. When jointing the face of a board, the concave or hollow face should be jointed first.<br />
18. Do not attempt to surface boards under ½” thick on the jointer.<br />
19. End grain must never be run over the jointer.<br />
20. Work should be held firmly against the table and fence.<br />
21. Push the stock far enough past the knives so that the guard will return before you pick up<br />
the stock.<br />
22. Never attempt to adjust the outfeed table, which must be set at the same level as the<br />
cutterhead knives.<br />
23. Turn off power after using jointer and stand by until machine has stopped.<br />
Methods of Operation:<br />
1. Consult instructor for doing specialized operations such as rabbeting or tapering.<br />
2. If stock is severely warped, cut stock (safely) into shorter lengths, if possible, before<br />
jointing. This will minimize the severity of the warp.<br />
3. Clean jointer with a bench brush.<br />
18
Lathe 16” x 42”<br />
The wood lathe is one of the few machines on which the operator can take a piece of rough stock<br />
and transform it into a finished work all on the same machine. Stock is mounted either on a face<br />
plate or between centers, and turned into various shapes by the operator using a variety of lathe<br />
chisels, controlled on the tool rest. Proper positioning of the tool rest and speed of the motor is<br />
essential to the safe operation of the wood lathe.<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection, face shield)<br />
• Getting hair/clothing caught in rotating parts or stock (Tie hair back, no loose clothing)<br />
• Being struck by stock flying off the lathe (Be sure stock is properly and securely mounted<br />
on the lathe)<br />
• Chisels being caught by work (Use proper spindle speed and tool rest placement; be sure<br />
chisels are sharp)<br />
Safety Rules:<br />
1. Wear eye protection. Students using the lathe must wear <strong>safety</strong> glasses and a face shield.<br />
2. Do not do any unauthorized operations on the lathe.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep your hands away from the stock and chucks when it is spinning.<br />
19
7. Feed chisels into the rotating stock cautiously and at a moderate rate of speed.<br />
8. Glued up stock must dry 24 hours before turning.<br />
9. All set-ups must be checked by instructor before turning on the lathe.<br />
10. Rotate work to be turned several times to be sure it clears tool rest and lathe bed.<br />
11. All stock over 4” square must have their corners chamfered before turning.<br />
12. Do not attempt to turn used wood or wood with knots, checks, cracks, and other defects.<br />
13. Rough and unbalanced stock must be turned to a round at a low speed. The lathe should<br />
not be allowed to vibrate. Unbalanced stock may become loose, vibrate and fly off the<br />
lathe.<br />
14. All centers must enter the wood at least 1/8”. Dead centers should be oiled or waxed<br />
before turning.<br />
15. Be sure faceplate screws are not so long as to enter into the portion of the wood being<br />
turned.<br />
16. All measuring of diameters with a caliper must be done while lathe is stopped.<br />
17. Turning tools must be held securely at tool rest and at extreme end of handle.<br />
18. Tail stock should be securely locked for all work between centers. Use tailstock center<br />
whenever possible, even when turning bowls.<br />
19. Remove push rod from spindle after knocking out live center.<br />
20. Centers must be removed while doing face-plate turning.<br />
21. Remove tool rest from lathe bed before sanding to avoid injury. Sanding should be done<br />
on the underside of the work.<br />
22. Lathe chisels must be kept sharp at all times. Dull tools are hard to control. Do not<br />
attempt to sharpen lathe chisels without proper instructions.<br />
23. When applying finish or polishing on the lathe, rag should be folded into a small pad, not<br />
wrapped around finger.<br />
24. Tool rest must be kept as close to the work as possible, and frequently re-adjusted as the<br />
work changes shape. Tool rest height should be approximately at centerline of work to be<br />
turned. Raise tool rest when using skew chisel; lower tool rest when using scrapers<br />
(square/round nose).<br />
25. Be sure the tool rest is firmly clamped to its holder and to the lathe bed.<br />
Methods of Operation:<br />
1. Spur centers are not to be forced into the work by means of tail stock spindle. USE A<br />
MALLET.<br />
2. All lathe equipment is color coded for each lathe. Keep all tools etc. with the appropriate<br />
lathe.<br />
3. Do not rest chisels on the lathe bed when making adjustments. They can easily fall and<br />
be damaged. Rather, place the chisel back in the tool rack.<br />
4. Cut faceplate stock round on the band saw before turning.<br />
5. Faceplates must be removed from wood stubs when finished with a turning.<br />
6. Stronghold chucks and jumbo jaws are to be removed from your work at the end of<br />
class.<br />
7. Used up sandpaper needs to be discarded. Usable sandpaper should be put in the<br />
appropriate place.<br />
8. Clean lathes with a bench brush.<br />
9. Students using the lathes are responsible for cleaning the lathes and the surrounding<br />
area. Mini lathes need to be vacuumed after use.<br />
20
Oscillating Spindle Sander ¾”<br />
The Oscillating Spindle<br />
Sander is used to sand<br />
concave (inside) curves.<br />
The spindle rotates in a<br />
counter-clockwise<br />
direction while<br />
simultaneously oscillating<br />
up and down. This action<br />
helps keep the abrasive<br />
sleeve from loading with<br />
sanding dust, wearing out,<br />
and overheating. Various<br />
spindle sizes can be used<br />
to accommodate different<br />
curves. The table also tilts<br />
to allow for sanding<br />
curves at different angles.<br />
Potential Hazards (and Their Mitigation):<br />
• Wood seized by sanding sleeve and thrown (hold work securely)<br />
• Wood seized by sanding sleeve and spun around on interior operation (maintain adequate<br />
clearance around spindle)<br />
• Dust inhalation (be sure dust collector is on)<br />
• Injuring fingers on abrasive (keep fingers clear of abrasive, do not sand small pieces, use<br />
correct sized throat plate)<br />
• Clothing/jewelry/hair seized by rotating spindle (avoid loose clothing, jewelry)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the spindle sander.<br />
21
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers a safe distance from the abrasive sleeve.<br />
7. Feed material into the machine at a moderate rate of speed.<br />
8. When changing spindles, turn off power at the disconnect box.<br />
9. Use the throat plate that leaves the smallest opening around the spindle.<br />
10. Hold stock securely when operating spindle sander.<br />
11. Always feed work into spindle drum from right to left direction against the direction of<br />
the spindle’s rotation.<br />
12. When sanding inside complete circles or other interior shapes, adequate clearance of 1<br />
inch must be maintained between sanding drum and stock.<br />
13. Do not sand small pieces on the spindle sander. Do not endanger your fingers.<br />
14. Do not reach under work or around sanding sleeve while spindle is rotating.<br />
15. Do not blow sanding dust off of sanding table.<br />
Methods of Operation:<br />
1. Spindle sanders should not be used to sand outside (convex) curves.<br />
2. Wrenches are to be used only for loosening spindles for removal. Hand-tighten spindles<br />
only. Using wrenches to tighten spindles will result in the spindle becoming stuck in the<br />
collet.<br />
3. For best results, always use the largest spindle possible for the curve you are sanding.<br />
4. Avoid excessive pressure on the spindle, which will result in excessive abrasive wear and<br />
poor results.<br />
5. Clean spindle sander with a bench brush.<br />
22
Panel Saw<br />
The Panel Saw is a<br />
machine designed<br />
to accurately<br />
dimension large<br />
sheets of panel<br />
goods, such as<br />
plywood and<br />
particle board. The<br />
material to be cut<br />
is placed on the<br />
stock support<br />
rollers, positioned<br />
by using the stop<br />
block, and cut by<br />
turning on the saw<br />
and sliding the<br />
saw and its<br />
carriage down the<br />
guide tubes. It can<br />
also be used for<br />
ripping sheet<br />
goods by rotating<br />
the saw on its<br />
carriage, fixing it<br />
at the appropriate<br />
height, and<br />
pushing the<br />
material through<br />
the saw on the<br />
stock support<br />
rollers.<br />
Potential Hazards (and their Mitigation):<br />
• Kerf closing during cut (Follow stock size restrictions)<br />
• Hands or fingers being injured by blade (Keep hands and fingers away from saw<br />
carriage)<br />
• Dust and/or debris in face or eyes (Wear eye protection)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the panel saw.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
23
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep hands and fingers well away from saw carriage; maintain a 4” margin of <strong>safety</strong>.<br />
7. Feed saw into material slowly and deliberately.<br />
8. Keep guards in place.<br />
9. Use only clean lumber, free of fasteners, checks, loose knots, sand, and paint.<br />
10. Once work is properly positioned, turn saw on, wait until it achieves its full RPMs, and<br />
push saw carriage slowly down to the bottom of its travel. Turn off saw after cut is<br />
completed.<br />
11. Wait for the blade to stop completely before raising the carriage to its resting position.<br />
12. Never cut a workpiece with a width smaller than that of the saw carriage.<br />
13. Do not place hands on or under saw carriage or in the path of the blade. Do not attempt to<br />
retrieve a piece of material while the blade is still turning.<br />
14. Do not force tool. Let the saw do the work.<br />
15. If the blade binds, stop carriage movement and turn off saw and wait for it to come to a<br />
complete stop. Notify instructor.<br />
Methods of Operation:<br />
1. Stop block can be attached to either side of the saw carriage for accurately dimensioned<br />
cuts.<br />
2. Load stock onto machine from right side if possible for ease of placement under holddowns.<br />
3. Saw will cut more cleanly on the back side of your workpiece. Plan accordingly.<br />
4. Clean panel saw with a bench brush.<br />
24
Planer 22”<br />
thickness.<br />
The Planer, or<br />
Thicknesser, is designed<br />
to surface the wood to a<br />
uniform thickness. The<br />
size of the planer is<br />
defined by the width of its<br />
cutterhead. For optimum<br />
results, rough lumber<br />
needs to be surfaced and<br />
flattened on one face on<br />
the jointer or surfacer,<br />
then put through the<br />
planer, smooth surface<br />
down on the infeed table.<br />
As the stock moves<br />
through the machine, fed<br />
by the infeed and outfeed<br />
rollers, a layer of wood is<br />
removed by the overhead<br />
rotating cutterhead. When<br />
properly adjusted, the<br />
lumber will then be<br />
surfaced on the opposite<br />
side and be of a uniform<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection, do not look into operating<br />
machine)<br />
• Getting hair/clothing caught on the moving wood (Tie hair back, no loose clothing)<br />
• Having fingers/hand pulled into machine (Keep hands from infeed roller and wood once<br />
it begins moving into machine)<br />
• Kickback (Machine should have anti-kickback fingers; stand to side of infeed table)<br />
Safety Rules:<br />
1) Wear eye protection.<br />
2) Do not do any unauthorized operations on the planer.<br />
3) Make adjustments only when the machine is at a dead stop (other than depth of cut).<br />
4) Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5) No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6) Keep fingers a safe distance from the infeed roller.<br />
7) Limit depth of cut to 1/16” or less.<br />
8) Use only stock 12” or longer, the distance between the infeed and outfeed rollers, on the<br />
planer.<br />
9) Use only clean lumber, free of fasteners, checks, loose knots, sand, and paint.<br />
25
10) Stock less than ¼” thick must not be planed unless supported by a heavier bearing board.<br />
11) Once stock is engaged in the machine, do not attempt to move it. Stay clear of stock to<br />
prevent clothing from being caught by machine.<br />
12) Do not stand directly behind stock when feeding it into the planer because of the possibility<br />
of a kickback.<br />
13) Never bend over to look at stock being planed. Chips can be thrown into your face.<br />
14) All special set-ups must be checked and approved by the instructor.<br />
15) Adjust the initial depth of cut to the thickest part of the board.<br />
16) Never change depth of cut after stock has been started through the planer.<br />
17) Always plane with the grain. Never plane across the grain; the planer will shred the wood.<br />
18) Wait for the machine to reach full speed before inserting wood.<br />
19) If the stock gets stuck in the planer, do the following, in this order:<br />
a) Gently push the stock into the planer; do not overly force the material.<br />
b) If that does not get the material moving, use a piece of scrap wood to shift the stock at a<br />
slight angle.<br />
c) If that does not work, lower table 1/8 of a turn of the adjustment wheel and repeat steps a<br />
and b until stock starts feeding again. Do not turn the wheel more than 1/8 turn at a time<br />
as the feed rollers may lose contact with the stock and a kickback could occur.<br />
Methods of Operation:<br />
1. Limit depth of cut to what machine can reasonably cut without bogging down, usually 1/16”.<br />
2. Plane pieces of varying thickness in progressive order, starting with the thickest first.<br />
3. Consider grain direction to avoid tear out; grain should be coming up toward the operator as<br />
it is being fed into the machine.<br />
4. Do not adjust the speed of the feed rollers. Only the instructor may do this.<br />
5. Long pieces of stock need to be supported by a person tailing off.<br />
6. Clean planer with a bench brush.<br />
26
Router Table<br />
The Router Table consists of a portable router mounted on the underside of a specially<br />
constructed table, collet side up, usually with a mechanism for raising and lowering the cutting<br />
bit. This arrangement allows for many special set-ups and for greater control of the cuts the<br />
router makes, as there is a fence along which to run the work, and a groove to control a miter<br />
gauge as well. Router tables are available in many styles, from the shop-made to elaborate<br />
commercial varieties.<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection)<br />
• Getting hair/clothing caught in the cutter (Tie hair back, no loose clothing)<br />
• Being injured by the cutter either when it is turning or stationary (Keep fingers away<br />
from cutters; use guards, hold-downs and feather boards)<br />
• Bit becomes loose in its collet (Be sure bit is tightened in the collet; bits that have a flare<br />
at the top of the shaft should be tightened below the flare)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the router table.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
27
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers a safe distance from the cutter. Always maintain a 4” margin of <strong>safety</strong>. Use<br />
push sticks, feather boards and hold-downs, or sliding fence when necessary.<br />
7. Feed material into the machine at a moderate rate of speed.<br />
8. Be sure all guards are in place.<br />
9. Use only clean lumber, free of checks, loose knots, sand, and paint.<br />
10. Be sure stock is clear of cutter before turning on router.<br />
11. Machine must be switched OFF and unplugged before any repair, cleaning, adjusting, or<br />
maintenance is done on it.<br />
12. Do not allow yourself to be distracted while work is in progress.<br />
13. Do not attempt to operate the router table if fatigued or otherwise unfit to perform the<br />
task at hand.<br />
14. Be sure vacuum is on before making any routs on stock. Vacuum turns on with the router.<br />
15. Clear all bit changes with the instructor.<br />
16. Use a slow speed for large cutters, and high speed for small cutters.<br />
17. Keep hands clear of the cutters.<br />
18. Hold wood firmly against the fence and feed slowly into the cutter from right to left.<br />
19. Use cutter guard and/or feather boards and hold-downs whenever possible.<br />
20. Never run stock between fence and cutter. Cutters should always be within the plane of<br />
the fence.<br />
Methods of Operation:<br />
1. Allow router to reach full speed before starting a cut.<br />
2. Make a test cut on a piece of scrap wood before routing work.<br />
3. To avoid unnecessary tear-out, always rout end grain first, then long grain.<br />
4. Do not attempt to make deep cuts in one pass. Begin with shallow cuts and increase the<br />
depth of cut incrementally.<br />
5. Do not allow a router bit to bottom out in the collet. It could come loose because of the<br />
flange on the shaft.<br />
6. Clean router table with a bench brush.<br />
28
Routers<br />
Routers are available in a great variety of sizes and configurations. Pictured above are just two of<br />
the most commonly used routers, a small Trim Router, capable of being operated with one hand,<br />
and a “D”-Handle Router, a larger and more versatile type. Plunge base routers are also common,<br />
allowing the operator to begin and end a cut in the middle of a board. Routers are used to apply<br />
decorative shapes to the edges of boards, rout rabbets and dados, and make specialty joints such<br />
as mortise & tenon, tongue & groove, and dovetails.<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection)<br />
• Getting hair/clothing caught in the rotating bit (Tie hair back, no loose clothing)<br />
• Being cut by the rotating bit (Keep fingers away from bit)<br />
• Bit becoming loose in its collet (Be sure bit is tightened in the collet; bits that have a flare<br />
at the top of the shaft should be tightened below the flare)<br />
• Stock kicking back (secure stock to workbench)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations with the router.<br />
3. Make adjustments only when the machine is at a dead stop, and unplugged from the<br />
power source.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers away from rotating cutting bits.<br />
29
7. Do not force router cutter into stock faster than necessary for clean cutting. Do not cause<br />
machine to reduce speed.<br />
8. Clear all cutting bit changes with instructor. Before changing bit, be sure router is<br />
unplugged. All bit changes must be inspected by instructor before use.<br />
9. Be sure on-off switch is in the off position before plugging cord in socket.<br />
10. Maintain a well-balanced position on both feet when handling the router.<br />
11. Hold router firmly when turning on switch. Some routers develop high torque suddenly<br />
when starting.<br />
12. Always check cutting depth adjustment of bits before turning on router.<br />
13. Work should be secured to the workbench when routing. Always keep both hands on the<br />
router.<br />
14. After turning off power, let router stop turning completely before setting machine down.<br />
15. Router should be moved in a counterclockwise direction around the outside edges of your<br />
work, and clockwise on interior (cut out) edges.<br />
Methods of Operation:<br />
1. Allow router to reach full speed before starting a cut.<br />
2. To avoid unnecessary tear-out, rout end grain first, then long grain.<br />
3. Make a test cut on scrap wood before routing your project, to be sure the bit is the<br />
appropriate one.<br />
4. Do not allow a router bit to bottom out in the collet. It could come loose because of the<br />
flange on the shaft.<br />
5. Do not attempt to make deep cuts in one pass. Begin with shallow cuts and increase the<br />
depth of cut incrementally.<br />
6. Secure cord before putting router away.<br />
30
Scroll Saw 24”<br />
The scroll saw is<br />
used for cutting<br />
tight radius curves<br />
and interior cuts in<br />
thin stock. Blades<br />
are typically 5”<br />
long and range is<br />
size from 1/32” to<br />
¼”. The smaller<br />
the blade size, the<br />
tighter the radius<br />
that can be cut.<br />
All scroll saws cut<br />
on the down<br />
stroke, pushing<br />
the work toward<br />
the table.<br />
However, there is<br />
considerable force<br />
acting on the<br />
wood during the<br />
up-stroke of the cycle so that the operator needs to hold the work firmly onto the table. This can<br />
be facilitated by making use of the “hold-down” that is designed for this purpose. Scroll saws are<br />
available in various types such as the fixed-arm, C-arm, and parallel-arm, pictured here. Scroll<br />
saws are not designed for heavy-duty cutting. Stock should be limited to ¾” thick for softwoods,<br />
and ½” thick for hardwoods.<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection)<br />
• Getting hair/clothing caught in the blade (Tie hair back, no loose clothing)<br />
• Being cut by the blade either when it is moving or stationary (Be aware of surroundings,<br />
keep fingers away from blade)<br />
• Blade bending and snapping (simplify complex curves; work slowly)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the scroll saw.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers a safe distance from the saw blade. Always maintain a 3” margin of <strong>safety</strong>.<br />
7. Feed material into the machine at a moderate rate of speed.<br />
8. Be sure all guards are in place. Guards may be removed with the instructor’s approval.<br />
9. For most operations, hold down must be adjusted so it rests on work.<br />
10. Never allow your hands to cross the line of cut.<br />
31
11. Cut only stock that has a flat surface that rests securely on the table.<br />
12. Turn machine by hand if possible to be sure all parts are clearing before turning on<br />
power.<br />
13. Hold work or material firmly.<br />
14. Machine must be at a complete stop before backing out of a cut.<br />
15. Keep waste from accumulating on the saw table. Machine should be at a stop when<br />
clearing scraps.<br />

Sliding Compound Miter Saw 12”<br />
The Sliding Compound Miter Saw, often referred to as a “Chop Saw,” is used for cross-cutting<br />
rough lumber to approximate length as well as cross-cutting dimensioned or finished stock to<br />
precise lengths and at various angles from 90° to ±45°. It is also capable of cutting compound<br />
angles. Its safe operation requires strict adherence to the <strong>safety</strong> and operating rules.<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece being thrown (Wear eye protection; use hold-down clamp)<br />
• Getting hair/clothing caught in the blade (Tie hair back, no loose clothing)<br />
• Being cut by the blade (Keep hands and fingers away from blade; maintain a 6” margin<br />
of <strong>safety</strong>)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the sliding compound miter saw.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers a safe distance from the saw blade. Always maintain a 6” margin of <strong>safety</strong>.<br />
Be sure to use the hold-down clamp and keep free hand behind your back<br />
33
7. Feed blade into the material at a moderate rate of speed.<br />
8. Stock dimension restrictions: 6” long minimum; 12 ½” wide maximum.<br />
9. Do not make any rip cuts on the sliding compound miter saw.<br />
10. Use only clean lumber, free of fasteners, checks, loose knots, sand, and paint.<br />
11. Work must be against the fence and secured to the saw table with the hold-down; free<br />
hand must be placed behind the back before making a cut.<br />
12. Be sure work is in contact with the fence at the point of the cut. Stock that bows away<br />
from the fence must be reversed before cutting. Failure to do so could cause the saw to<br />
kick back.<br />
13. When using the sliding compound miter saw to cut a wide piece of stock, blade must be<br />
fully extended (toward the operator) while in the up position, started and allowed to reach<br />
its full rpm’s, then slowly lowered and pushed through the stock until cut is completed.<br />
14. When cutting narrow stock, the blade may be left in its resting position, started, and<br />
pushed down through the work.<br />
15. Wait until saw blade has come to a complete stop before raising it to its resting position.<br />
16. When using the stop block, hold-down clamp must be on the same side of the blade as the<br />
stop block.<br />
17. When using the stop block to cut small pieces (6” minimum length), use the 10” spacer<br />
block and clamp your work, not the spacer block.<br />
18. Wait until the saw has come to a complete stop and remove all wood chips from saw<br />
table after using saw and before every cut.<br />
19. Cut only one piece at a time on the sliding compound miter saw.<br />
20. Never allow your hand to be in the line of cut.<br />
Methods of Operation:<br />
1. Test all miter set-ups on scrap wood before cutting project.<br />
2. Turn on vacuum switch before making any cuts.<br />
3. Clean miter saw with a bench brush. Vacuum must be emptied periodically.<br />
34
Table Saw 10”<br />
The Table Saw,<br />
as its name<br />
implies, consists<br />
of a table through<br />
which a circular<br />
blade can be<br />
elevated. It is<br />
used to accurately<br />
rip and crosscut<br />
lumber and sheet<br />
goods. It can also<br />
be used to create<br />
dadoes and<br />
rabbets, and, with<br />
the help of<br />
special jigs, joints<br />
such as tenons<br />
and box joints. In<br />
addition, the<br />
blade can be<br />
tilted for cutting<br />
chamfers, bevels,<br />
miters, and<br />
compound miters.<br />
Freehand cutting<br />
is strictly prohibited on the table saw. The size of the table saw is determined by the diameter of<br />
its blade.<br />
cross-cutting panels up to 36 inches.<br />
NOTE: The SawStop brand table saw illustrated here<br />
incorporates a digitally controlled start/stop<br />
mechanism, which works with the built-in blade<br />
braking system to add a layer of <strong>safety</strong> not available<br />
with other table saws. In order to operate the saw, the<br />
power needs to be turned on at the disconnect box, and<br />
switched on at the control panel. The saw blade is then<br />
started and stopped with the large red paddle by<br />
pulling it to start, and pushing it to stop. The paddle is<br />
situated so as to make it easy to stop the saw with<br />
one’s leg or knee, thus freeing both hands to maintain<br />
control of the work.<br />
Students need to be personally checked out on the<br />
table saw by the instructor at the beginning of each<br />
year regardless whether they have been previously<br />
checked out.<br />
The saw illustrated here also incorporates an<br />
aftermarket sliding table mechanism, which includes a<br />
miter fence and allows for accurate mitering, and<br />

Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection)<br />
• Kick-back of stock (Be sure anti-kick-back splitter and fingers are in place; stand to one<br />
side of the path of the blade)<br />
• Being cut by the blade (Be sure guard is in place; keep fingers away from blade; use push<br />
sticks; do not pick up scraps until blade has stopped turning)<br />
• Wood binds on the blade; blade is seized by the wood (When feeding stock into the<br />
blade, make sure to hold the wood firmly and pressed up against the fence)<br />
• Getting clothing caught in the blade (No loose clothing)<br />
Safety Rules:<br />
1. Wear eye protection.<br />
2. Do not do any unauthorized operations on the table saw.<br />
3. Make adjustments only when the machine is at a dead stop.<br />
4. Make sure that no one but the operator is inside the operator’s <strong>safety</strong> zone.<br />
5. No jewelry or long sleeve clothing. Long hair must be tied back.<br />
6. Keep fingers a safe distance from the saw blade. Always maintain a 4” margin of <strong>safety</strong>.<br />
Use push sticks when necessary.<br />
7. Feed material into the machine at a moderate rate of speed.<br />
8. Be sure all guards and the riving knife are in place. The guards and riving knife may be<br />
removed only when the instructor has authorized their removal for special set ups.<br />
9. Never allow your hands to cross the line of cut.<br />
10. Cut only stock that has a flat surface that rests securely on the table and against rip<br />
fence.<br />
11. Be sure to push the wood past the back edge of the blade and past the riving knife in<br />
order to avoid kickback.<br />
12. Hold work or material firmly.<br />
13. Keep waste from accumulating on the saw table. Blade should be stopped when clearing<br />
scraps.<br />
14. Limit saw blade height to one saw tooth above stock to be cut.<br />
15. Minimum length of stock when ripping is 12”. Minimum length for crosscutting is 8”.<br />
Minimum width for rip is 1 ½”. Instructor’s help must be obtained for exceptions to this<br />
rule.<br />
16. Use approved push sticks when ripping pieces narrower than 6 inches. Do not endanger<br />
fingers.<br />
17. Use only clean lumber, free of fasteners, checks, loose knots, sand, and paint.<br />
18. Be sure saw teeth point toward you as you stand on the operator side of the saw.<br />
19. Use ripping fence for ripping; use the miter gauge or sliding table fence for cross-cutting<br />
on the table saw. Never use both together.<br />
20. Use a clearance block clamped to the rip fence when cross cutting several identical<br />
pieces.<br />
21. Never free-hand cut on the table saw. It is dangerous and will result in a kickback.<br />
22. Be sure ripping fence is locked in place before ripping.<br />
23. Be sure the stock is not in contact with the blade before turning on machine.<br />
24. Always have a helper tailing off stock. Person tailing off should only support stock and<br />
not attempt to guide or pull it.<br />
25. Only operator should push the material, and only as fast as the saw will freely cut.<br />
36
26. Stand to one side of the line of the saw to avoid kickback danger and keep hands clear of<br />
the saw path.<br />
27. When ripping, set rip fence to the desired dimension. Scrap will be to the left side of the<br />
blade.<br />
28. Never reach behind the saw blade and attempt to pull stock through.<br />
29. Never reach over the saw blade or pass work over the blade while it is running. If the<br />
work is dropped it could result in a kickback.<br />
30. All special set-ups and dado heads must be inspected by the instructor before power is<br />
turned on. The guard must be removed for dado work.<br />
31. All blade changes must be checked by the instructor.<br />
32. Plunge cutting on the table saw (pushing material down onto a rotating blade) is strictly<br />
forbidden.<br />
33. No cylindrical or round stock is to be cut on the table saw.<br />
34. Do not be distracted when operating the table saw. Turn off saw, and move out of the<br />
operator’s <strong>safety</strong> zone before responding to anyone attracting your attention.<br />
35. Do not distract anyone operating the table saw<br />
36. Be sure the saw is completely stopped and blade is lowered below table before walking<br />
away from it.<br />
37. Never back wood away from a running blade. Doing so can result in a kickback.<br />
Methods of Operation:<br />
1. Allow saw to reach full speed before starting a cut.<br />
2. Dado heads must be removed after use.<br />
3. Be sure dust collector gate is open.<br />
4. Clean table saw with a bench brush.<br />

Vertical Belt and Disc Sander 6” – 12”<br />
The vertical belt/disc<br />
sander combination is a<br />
very versatile machine. It<br />
allows for sanding stock<br />
with precision and, with<br />
the use of a miter gauge<br />
and tilted table (up to 45<br />
degrees), at various<br />
angles and compound<br />
angles. The diameter of<br />
the disc and the width of<br />
the belt indicate the size<br />
of the machine, in this<br />
case 12” and 6”<br />
respectively.<br />

this may cause the wood to catch the edge of the belt and rip or cause it to come off.<br />
Methods of Operation:<br />
1. Allow sander to reach full speed before starting to sand.<br />
2. Use miter gauge whenever possible to assure accuracy.<br />
3. Keep stock moving from side to side when sanding to avoid abrasive wear and heat build<br />
up.<br />
4. Do not use the vertical belt or disc sander for joinery, squaring stock or similar<br />
operations. They do not have the precision required for such operations.<br />
5. Maximum length or width of stock to sand is 6 inches.<br />
6. Avoid sanding concave surfaces.<br />
7. Clean vertical belt sanders with a brush.<br />
39
Wide Belt Sander 15” (30”)<br />
The wide belt sander<br />
is used to sand the<br />
surface of stock or<br />
glue-ups up to 30”<br />
wide. It consists of a<br />
15” wide abrasive<br />
belt, and a conveyor<br />
belt feed table that<br />
guides the work<br />
through the machine.<br />
Because this is an<br />
open-ended sander,<br />
work up to 30” wide<br />
can be sanded by<br />
turning the work<br />
180° and putting it<br />
through a second<br />
time. The size of a<br />
wide belt sander is<br />
determined by the<br />
width of its feed<br />
table. They are<br />
available up to 60”<br />
wide.<br />
Potential Hazards (and their Mitigation):<br />
• Dust or debris/ work piece in the eyes (Wear eye protection)<br />
• Getting hair/clothing caught in the belt (Tie hair back, no loose clothing)<br />

30” wide double pass.<br />
8. Be sure the compressed air valve is open before setting up the machine.<br />
9. Be sure belt is fully on top roller before securing belt in place (with lever). This usually<br />
requires squeezing belt together to clear fittings when installing.<br />
10. Be sure dust collector is on and dust gate is open before operating machine.<br />
11. Do not operate machine with side access doors open.<br />
12. All set-ups must be inspected by the instructor before machine is turned on.<br />
13. Set feed table height so stock fits snugly under infeed roller.<br />
14. Do not jam workpiece into machine during operation. Ease workpiece into machine<br />
under front roller using light pressure.<br />
15. Do not sand any stock thinner than 1/8”. Do not sand stock any shorter than 12”.<br />
16. Do not attempt to sand thin stock by using a “dummy”, or backer board under<br />
workpiece.<br />
17. No used lumber. Use only clean lumber, free of fasteners, checks, loose knots, sand, and<br />
paint.<br />
18. Never sand more than one piece of stock at a time.<br />
19. Raise conveyor feed table 1/8 turn (1/64”) for each setting (like compass directions).<br />
20. Watch load gauge when feeding work. Needle should not go into red zone.<br />
21. Do not stand directly behind conveyor feed table when operating machine.<br />
22. Do not leave the machine running unattended.<br />
23. Be sure power is turned off before changing belt.<br />
24. Turn off power and air valve before leaving machine.<br />
Methods of Operation:<br />
1. Turn work 180° and feed through a second time before raising feed table again.<br />
2. Change sanding grits incrementally (80, 100, 150) for best results.<br />
3. If burn marks appear, sanding belt is dull and should be replaced.<br />
4. Clean wide belt sander with brush.<br />
41
Compressed Air Hoses<br />
The compressed air hoses are used to operate the finish spray equipment and the nail guns, both<br />
of which are to be used by Advanced Wood Technology students only (under instructor<br />
supervision). All Wood Technology students are allowed to use the compressed air to carefully<br />
blow dust off of their projects prior to applying a finish, and to clean their clothing at the end of<br />
class, after tool pick-up and shop clean-up have been completed, and subject to the following<br />
rules.<br />
1. Obtain permission from instructor before using compressed air.<br />
2. Always wear eye protection when using compressed air as dust and debris may blow<br />
back in your face.<br />
3. When using compressed air to clean off projects, be sure no other student is around<br />
you, and direct air in a downward direction.<br />
4. Do not blow compressed air in the direction of another person. Do not blow<br />
compressed air into your or anyone else’s ears, nose, or mouth.<br />

Appendix 2<br />
Instructions on How to Add and Label Your Own Machine Photographs<br />
In order to tailor this <strong>manual</strong> to your specific machinery, directions are given below on how to<br />
create and label photographs to replace those in the <strong>manual</strong>. The document is in Microsoft Word<br />
format, and all photographs are in jpg format. If you would like an electronic version of this<br />
<strong>manual</strong>, email Don Dupont: donaldupont@gmail.com<br />
All photographs are taken digitally in black and white mode and at relatively low resolution<br />
(1600 x 1200 pixels; approximately 374KB). This is done in order to keep the document size<br />
small enough to easily manipulate and send by email. When taking photographs to include in<br />
your <strong>manual</strong>, try to keep them at approximately this size. In some photos, I used some 1/8”<br />
plywood sheets as a backdrop to eliminate background clutter and distractions.<br />
Labeling is done is Adobe Photoshop or Photoshop Elements. For this information I am grateful<br />
to Tony Fortner the staff at the Cerritos College woodworking program.<br />
Begin by opening Photoshop or Photoshop Elements. Close the welcome screen and go to File<br />
and Open. This is where you locate and open your photo file. How you do this depends on what<br />
system you’re using. I use a Mac and iPhoto, and I need only type in the name of the photo file<br />
in the search window to bring it up on the screen. Ignore the Embedded Profile Mismatch<br />
window that asks how you want to proceed and discard the embedded profile and continue. Once<br />
you have your photo in Photoshop, you can then begin to label it. Labeling is done using the Text<br />
button (the button with the capital T). Click on this and it will allow you to select the size and<br />
color of the letters you will use. The labels in this document were created using regular Arial<br />
font, 40 pt., justified left, in black. All first letters of the words in the labels are capitalized. Once<br />
you have typed the label, you can then move it to an appropriate location by left clicking and<br />
dragging it. The labels are best located on a light background to be visible. Continue creating and<br />
locating all the labels. To create a second label, you will need to click on another button to<br />
“reset” the text button to make it activated for your next label. You can also click on any existing<br />
label to re-activate the move function and relocate the label.<br />
Once the labels are created, arrows must be added for clarity. This is done using he line tool,<br />
which looks like a backslash. Once you click on this, you can select the weight of the line (I used<br />
.06), and the add arrowheads by clicking on the down arrow at the right of the line tool toolbar<br />
and selecting “end of line” for the position of the arrowhead. Once you’ve done this, it is simply<br />
a matter of clicking and dragging in any direction to create the arrows. Of course, you can<br />
change the color if you wish, but in this document I have tried, for clarity, to be consistent, using<br />
black throughout.<br />
Once you have completed the labeling, save your photograph as a jpg file to an appropriate<br />
folder, giving it a recognizable name so you can then insert it into the document.<br />
To replace a photograph in the document, simply click on the photograph and delete it. Then you<br />
may insert your own replacement photograph by going to the Insert menu, selecting From File,<br />
and selecting your saved labeled photograph. Once you’ve inserted you own photograph,<br />
clicking on it will bring up the Formatting menu. Select Format Picture, Layout, and then Tight<br />
in order to have the text wrap around the photograph. You can also make the picture smaller by<br />
selecting Picture and cropping it for a better fit, or make the entire photograph smaller by<br />
shrinking it from a corner box. Once you become familiar with the processes, it takes very little<br />
time to make these changes. If you encounter any difficulties, your resident tech or digital<br />
photography instructor should be able to help.<br />
