INSTALLING 

Locate the machine on a solid foundation, allowing sufficient area all around for easy 

working and maintenance (see Foundation Plan). The Lathe may be used free-standing 

or bolted to the foundation. 

Free-standing: Position Lathe on foundation and adjust each of the six mounting feet to 

take equal share of the load. Then using an engineers precision level on the bedways 

(as in Figure 5), adjust the feet to level up machine. Periodically check bed level to 

ensure continued Lathe accuracy. 

Fixed installation: Position Lathe over six bolts (1/2 in. or 12 mm diam.) set into the 

foundation to correspond with holes in the mounting feet. Accurately level the machine 

as in Figure 5, then tighten hold-down bolts and recheck bed level.

CHUCKS AND CHUCK MOUNTING 

WARNING: GREY-IRON CHUCKS MUST NOT BE FITTED ON THIS HIGH-SPEED 

LATHE. USE ONLY DUCTILE IRON CHUCKS. 

When fitting chucks or faceplate, first ensure that spindle and chuck tapers are scrupulously 

clean and that all cams lock in the correct positions. See Figure 7, it may be 

necessary when mounting a new chuck to re-set the Camlock Studs (A) to do this. Remove 

the Cap-head Locking Screws (B) and set each stud so that the Scribed Ring (C) 

is flush with the rear face of the chuck-with the slit lining up with the locking screw hole 

(See Figure 7). 

Now mount the chuck or faceplate on the spindle nose and tighten the three cams in 

turn. It must be fully tightened. If any of the cams do not tighten fully remove the chuck 

or faceplate and re-adjust the stud. Fit and tighten the Locking Screw (B) at each stud 

before remounting the chuck for work. 

This will assist subsequent remounting. DO NOT INTERCHANGE CHUCKS OR FACE 

PLATES IF LATHE WITHOUT CHECKING UP CORRECT CAMLOCKING. 

IMPORTANT: Take note of speed limitations when using faceplate. 10 inch faceplates 

should not be run at speeds greater than 770 rev/min.

THREADING DIAL INDICATOR 

A. Whitworth Threads 

Located on right-hand side of the Apron on lathes having an English leadscrew. Engage the 

indicator pinion with the leadscrew and tighten the handnut to retain indicator in engagement. 

To cut threads of an even number per inch, close the leadscrew nut as ANY line on the dial 

passes the datum mark. To cut threads of odd number per inch, close the leadscrew nut at 

any NUMBERED line. Fractional threads of 1/2 or 1/4 T.P.I. may be cut by closing the nut at 

the SAME numbered line on each pass of the tool. This dial cannot be used with an English 

leadscrew to cut metric threads, or fractional threads. For these the leadscrew nut must be kept 

closed and the machine revered by use of the Change-over switch, after each cutting pass and 

tool with drawal. 

B. Metric Threads 

The thread dial used for cutting metric screw threads on lathes equipped with metric leadscrew. 

To provide for the various lathes equipped with metric leadscrew. To provide for the various 

pitches of metric threads, several gears have different numbers of teeth are mounted on the 

lower end of the shaft. The vertical position of the thread dial indicator is changed as required 

so that the correct gear for the pitch of the thread to be cut will mesh with the leadscrew. Each 

graduation on the dial is marked with a letter which indicates the points at which the halfnuts 

may be engaged for certain threads. A diagram is supplied with the thread dial to show which 

gear and which graduations must be used for each pitch of metric screw thread.

SERVICE & MAINTENANCE 

LATHE ALIGNMENT (PART 1) 

With the Lathe installed and running, we recommend a check on machine alignment 

before commencing work. Check leveling and machine alignment at regular periods to 

ensure continued Lathe accuracy. 

Headstock check: Take a light cut-with a keen tool over a 6 in. (150mm) length of 2 in. 

dia. (50mm) steel bar gripped in the chuck but not supported at the free end. Micrometer 

readings at each end of the turned length (at A and B of Figure 19) should be the 

same. 

To correct a difference in readings, slacken and release the four headstock hold-down 

screws (J) shown in Figure 19 and adjust the set-over pad (K) beneath the headstock. 

Then tighten all screws. After adjustment, repeat the test -cut/micrometer-reading until 

micrometer readings are identical so that machine cutting will be absolutely parallel.

LATHE ALIGNMENT (PART 2) 

Tailstock check: Using a 12 in. (305mm) ground steel bar fitted between centers of 

Headstock and Tailstock. Check the alignment by fitting a dial-test indicator to the 

topslide and traversing the center line of the bar. 

To correct error, release the Tailstock Clamp Lever and adjust the two set-over screws 

provided. Continuously check and correct until the alignment is perfect.

END GEAR TRAIN 

Drive from Headstock to Gear-box is transmitted 

through a gear train enclosed by the 

Headstock end-guard. Intermediate gears are 

carried on an Adjustable Swing Frame (M). 

HEADSTOCK 

Gears must be thoroughly cleaned before 

fitting and backlash maintained at .005 in. 

(.127mm). Lubricate gears regularly with thick 

oil or grease.

DRIVING BELTS 

PULLEY 

To alter belt tension, remove the coverplate in 

back of the Headstock Block and adjust the 

two Screws (X) on the hinged motor platform. 

Ensure that the motor is correctly aligned with 

the Lathe Axis. 

Light finger pressure at a point midway between 

Motor and Headstock Pulleys should 

produce about 3/4 in. (19mm) movement of 

each belt when under correct tension.

SLIDE WAYS ATTENTION 

Tapered gib strips are fitted to 

slideways of saddle cross-slide and top 

(compound) slides so that any slackness 

which may develop can be rectified. 

Ensure that slideways are thoughly 

cleaned and lubricated before 

attempting adjustment. Then reset the 

gibs by slackening the rear gib screw 

and tightening the front screw. Check 

constantly for smooth action throughout 

full slide travel. Avoid over-adjustment 

which can result in increased wear-rate 

and stiff or jerky action.

CROSS-SLIDE NUT 

This is adjustable for elimination of 

slackness which may develop in service. 

Reduce back-lash by the cap-head 

screw in the rear of the nut. Then make 

only small adjustment by the cap-head 

screw. Before operating the cross-slide, 

check several times by hand to be sure 

of smooth operation throughout travel.

LUBRICATION (PART 1) 

The headstock and gearbox are splash-lubricated from an internal reservoir of oil (Shell 

Tellus 27). Check the oil level constantly to the mark on the oil sight window in the 

front end face of the headstock and gearbox. A weekly check is recommended. The 

oil needs to be changed every year. Oil through a filler cap in the top of the headstock 

and gearbox is covered by the end-guard. Drain from a drain plug in the bottom of the 

headstock and gearbox. 

The Apron is lubricated from an internal reservior of oil. The oil sight window is in the 

front of the Apron. A filler cap is in the top of the Saddle. Refill the reservoir to the level 

of the oilsight with Shell Tonna oil 33. The Apron can be drained by unscrewing a hexheaded 

drain plug in the bottom.

LUBRICATION (PART 2) 

In addition, oil gun is provided for the Saddle, Cross-slide, Cross-slide Nut and Top- 

Slide (compound slide) to oil. Leadscrew using a oil gun can be oiled with light machine 

oil or way lubricant. 

On the Tailstock, oil points are provided for daily attention from a standard oil can. 

It is recommended that all slideways, leadscrew and feed shaft are cleaned off (a bristle 

paint brush is useful for this) and lightly oiled after each period of work. 

NOTE: Using incorrect grades of oil can cause damage.

Limited 1 year / 90 Day warranty 

Harbor Freight Tools Co. makes every effort to assure that its products meet high 

quality and durability standards, and warrants to the original purchaser that for a period 

of ninety days from date of purchase that the engine/motor, the belts (if so equipped), 

and the blades (if so equipped) are free of defects in materials and workmanship. Harbor 

Freight Tools also warrants to the original purchaser, for a period of one year from date 

of purchase, that all other parts and components of the product are free from defects in 

materials and workmanship (90 days if used by a professional contractor or if used as rental 

equipment). This warranty does not apply to damage due directly or indirectly, to misuse, 

abuse, negligence or accidents, repairs or alterations outside our facilities, normal wear and 

tear, or to lack of maintenance. We shall in no event be liable for death, injuries to persons 

or property, or for incidental, contingent, special or consequential damages arising from 

the use of our product. Some states do not allow the exclusion or limitation of incidental or 

consequential damages, so the above limitation of exclusion may not apply to you. This 

warranty is expressly in lieu of all other warranties, express or 

implied, including the warranties of merchantability and fitness. 

To take advantage of this warranty, the product or part must be returned to us with 

transportation charges prepaid. Proof of purchase date and an explanation of the complaint 

must accompany the merchandise. If our inspection verifies the defect, we will either 

repair or replace the product at our election or we may elect to refund the purchase price 

if we cannot readily and quickly provide you with a replacement. We will return repaired 

products at our expense, but if we determine there is no defect, or that the defect resulted 

from causes not within the scope of our warranty, then you must bear the cost of returning 

the product. 

This warranty gives you specific legal rights and you may also have other rights which 

vary from state to state.
