ASSEMBLY INSTRUCTIONS FOR SINGLE AXLE WITH PISTON PUMP<br />
1. After the undercarriage is attached to the main frame,<br />
slide <strong>Axle</strong> (#2) into the Undercarriage (#1) so that your<br />
particular row spacing is achieved. (REFER to View A).<br />
Secure slide in axle tube using one 5/8" x 6" hex head bolt<br />
(#3), 5/8" x 7" hex head bolt (#4) and four 5/8" flat washers<br />
(#6), and two 5/8" nylon insert locknuts (#5).<br />
8. Attach the Piston Pump to the Left PP Mount using two<br />
3/8" x 1-1/4" hex head bolts (#39), 3/8" flatwashers (#40)<br />
and 3/8" nylon insert locknuts (#33). Then attach the Piston<br />
Pump and the Chain Tightener Bracket (#38) to the Right<br />
PP Mount using four 3/8" x 1-1/4" hex head bolts (#39),<br />
3/8" flatwashers (#40) and 3/8" nylon insert locknuts (#33).<br />
If you are attaching a Piston Pump to your single axle<br />
sprayer skip to step #4<br />
2. Attach the two Spindle Mounts (#7) to the two Slide-in-<br />
<strong>Axle</strong> Tube using Spindle Mount, twelve 5/8" x 2" hex head<br />
bolts (#8), and nylon insert locknuts (#5).<br />
3. Attach rim and tire assembly to the Hub (#20) using eight<br />
5/8" lug bolts (#21).<br />
4. Attach the Spindle Mount (#7) to the Right Side Slide-in-<br />
<strong>Axle</strong> Tube using, six 5/8" x 2" hex head bolts (#8), and<br />
nylon insert locknuts. Attach the Spindle Mount (#7) and<br />
the Bearing Mount Angle Plate (#10) to the Left Side Slidein-<strong>Axle</strong><br />
Tube using Spindle Mount, four 5/8" x 2" hex head<br />
bolts (#8), two 5/8" x 2-1/2" hex head bolts (#9),and six<br />
5/8" nylon insert locknuts (#5) .<br />
NOTE: Use 5/8" x 2-1/2" bolts in Holes A and B.<br />
5. When The Piston Pump is used remove the Hub (#20) by<br />
removing Hub Cap (#27), Cotter Pin (#25) and Castle Nut<br />
(#26). Slide the hub off the shaft. Do not drop bearing<br />
onto ground and do not cut or ruin seal. Bolt the<br />
Sprocket Mounting Plate (#14) to the back side of the Hub<br />
(#20) using four 1/2" x 1" fine thread bolts (#15) and 1/2"<br />
lockwasher (#16). Bolt the 50 tooth sprocket (#11) to the<br />
Sprocket Mounting Plate using five 3/8" x 3/4" bolts (#12)<br />
and 3/8" lockwashers (#13).<br />
6. Reinstall the hub onto the spindle making sure the inside<br />
bearing is seated properly into bearing race. Place ouside<br />
bearing onto shaft and into bearing race of hub. Install<br />
washer and nut. Torque nut to 25 - 30 foot-lbs. with out<br />
spinning the hub, loosen nut and spin nut back on so it is<br />
finger tight. Replace cotter pin and Hub Cap. Mount the<br />
rim and tire assembly using eight 5/8" x 1-1/2" fine thread<br />
lug bolts (#21).<br />
9. Attach the Idler Sprocket (#42) to the Chain Tightener<br />
Bracket using one 1/2" x 2-1/4" hex head bolt (#41), four<br />
1/2" flatwashers (#43) and one 1/2" nylon insert locknut<br />
(#43). Use flatwashers to align Idler Sprocket.<br />
10.Bolt the Bearing Channel Mount (#34) to the Under Carriage<br />
between the PP Mounts using two 3/8" x 6" hex head<br />
bolts (#36), two 3/8" nylon insert locknuts (#33), and one<br />
Bearing Channel Back Plate (#35).<br />
11.Attach the two Pillow Block Bearings (#45) to the Bearing<br />
Mount Angle Plate (#10) and the Bearing Channel Mount<br />
(#34), using four 7/16" x 1-1/2" hex head bolts (#46) and<br />
7/16" nylon insert locknut (#47) and eight 3/8" flatwashers<br />
(#40).<br />
12.Insert the shaft into the pillow block bearings making sure<br />
the bearing lock collars are on the inside of pillow block<br />
bearings. Do not lock collars at this time. Place the 18 tooth<br />
Sprocket toward the wheel and place the 24 tooth sprocket<br />
toward the PP with the hubs facing toward the pillow block<br />
bearing. Line up sprockets tighten set screws on sprockets<br />
and lock collars on pillow block bearings. Attach Wheel<br />
Drive Chain (#53). Tighten chain by sliding the bearing in<br />
the slots. If proper tension of the chain cannot be achieved<br />
insert the proper number of Bearing Shims between the<br />
pillow block bearings and Bearing Mount Angle Plate. Insert<br />
the same number of shims between the pillow block bearings<br />
and Bearing Channel Mount. Route the Idler Chain<br />
(#54) as shown and tighten by sliding in the slots on the<br />
chain tightener bracket. Make sure all fasteners are tight<br />
before using sprayer.<br />
7. When mounting a double piston pump to the under<br />
carriage attach the Right Piston Pump Mount (#29) to the<br />
Under Carriage (#1) 6-1/2" from edge of frame to the<br />
mount and mount the Left Piston Pump Mount 5-1/4"<br />
between brackets when mounting a single PP and<br />
10-1/2" when mounting a double PP using four 3/8" x<br />
8-1/2" bolts (#31), 3/8" nylon insert locknuts (#33), and<br />
two Piston Pump Mount Back Plates (#32).<br />

SPRAYER CHECKLIST:<br />
Downtime in the fields caused by field breakdowns is costly and time consuming. Many breakdowns can be eliminated<br />
by periodic equipment maintenance. By spending a little time reviewing this checklist before seasonal spraying<br />
application time and following proper after-season care, you can save time and money later on.<br />
Check Before Going To The Field:<br />
1. NOZZLES<br />
Check the tip for excessive wear by checking for grooves<br />
in or near the tip opening. Check the nozzle spacing by<br />
starting at center and working outwards. Check boom for<br />
proper height.<br />
2. HOSES<br />
Check all hoses for worn or soft spots. Be sure all hose<br />
clamps are tightened. Be sure no hoses are kinked or<br />
pinched. Check for leakage in any of the lines.<br />
3. TANK<br />
Remove and clean the agitator orifices. Check the orifices<br />
for excessive wear by checking for grooves in or<br />
near the orifice opening. Be sure the tank tie down bands<br />
are tight. Inspect fittings and gaskets to insure they are in<br />
good condition.<br />
4. CONTROLS<br />
Check for leakage, plugging, or wear on all valves,<br />
fittings, etc. Clean off any build up of foreign material. Be<br />
sure the pressure gauge is working properly. Clean the<br />
strainer and make sure the “O” ring is not cracked as this<br />
could cause leakage.<br />
After Season Care:<br />
1. After spraying chemicals, run water mixed with cleaners<br />
through the tank, pump and all hose hookups. If wettable<br />
powder dries out in the system, it is very difficult to put<br />
back into suspension and can cause malfunction, damage<br />
or injury.<br />
2. The tank, when cleaned, should have all openings closed<br />
or covered to keep dirt from blowing in.<br />
3. The pump should be flushed with soluble oil and the<br />
pump ports plugged to keep out moisture and air.<br />
4. Clean the strainer thoroughly.<br />
5. Disassemble the tips and rinse with water or cleaning<br />
solution. (Appropriate for chemical sprayed).<br />
6. Clean the tip opening with a wooden toothpick. Never use<br />
wire or a hard object that could distort the opening.<br />
7. Water rinse and dry the tips before storing.<br />
5. PUMP<br />
Check to be sure the pump turns freely. Be sure to prime<br />
the agitation pump before starting to prevent damage to<br />
the seals. Check the PTO shaft knuckles and be sure the<br />
set screw is tight and the drive pin is in place and grease<br />
PTO shaft.<br />
6. FRAME<br />
Be sure all bolts are tightened. Be sure to grease all<br />
grease fittings. Check sprayer tire pressure and grease<br />
the axle.<br />
7. SPRAYER<br />
Replace all worn or damaged parts.<br />
SAFETY FIRST<br />
To keep the sprayer from tipping backwards when unhitching<br />
from the tractor: For HPS, always lower the rear<br />
safety stand. For HPT, make sure weight transfer spring<br />
tension is correct for proper tongue weight.<br />
Keep the PTO Shaft as level as possible between the<br />
pump shaft and tractor PTO to minimize PTO jumping<br />
from an excessive angle which could result in pump or<br />
PTO damage.<br />
Take note after the sprayer is hitched to the tractor draw<br />
bar that the end of the PTO shaft that goes on the tractor<br />
PTO is at least 3 feet from the pump shaft. The pump shaft<br />
could be broken off when turning sharp corners if this is<br />
not done.<br />
KEEP HANDS, FEET, AND LOOSE CLOTHING AWAY FROM ROTATING PARTS.<br />
NOTE: DETHMERS MANUFACTURING COMPANY does not and will not make any recommendations concerning the<br />
application of various chemicals or solutions. These recommendations relate to either amount or procedure<br />
of materials applied.<br />
If you have any questions regarding the application of certain chemicals or solutions, contact your chemical<br />
supplier and follow chemical manufacturer recommendations.<br />
