13. This machine demands your attention. To prevent loss of control or tipping of the vehicle:
A. Use extra caution in backing up the vehicle. Ensure area is clear.
B. Do not stop or start suddenly on any slope.
C. Reduce speed on slopes and in sharp turns. Use caution when changing directions on slopes.
D. Stay alert for holes in the terrain and other hidden hazards.
14. Before leaving operator’s position:
A. Disengage all drives.
B. Set park brake.
C. Shut engine off and remove the ignition key.
D. If engine has to run to perform any maintenance keep hands, feet, clothing and all other parts of
body away from moving parts.
15. Keep hands, feet and clothing away from moving parts. Wait for all movement to stop before you clean,

insure the safety of themselves and others,
1. WEAR protective clothing including: gloves, hat, respirator, eye protection and skin covering suitable for
protection from chemicals being used.
2. BATHE thoroughly after any exposure to chemicals, giving particular attention to eyes, nose, ears and
mouth.
3. CLEAN equipment and materials in accordance with employer, municipal and state regulations. Use
only approved areas and drains.
4. DISPOSE of chemicals and rinse solutions by approved and legal means.
5. PROVIDE methods and materials for operators to wash eyes and hands immediately during the
spraying process.
6. PROVIDE methods and materials for control, safe dilution and neutralization of chemical spills during
preparation, spraying, transporting and cleanup.
7. Always check and follow the directions and safety warnings of the chemicals to be used.
8. Secure the discharge lines before starting the pump.An unsecured discharge line may whip.
9. Periodically inspect the pump and the system components.
10. Check hoses for weak or worn condition before each use. Make certain that all connections are tight
and secure.
11. Do not operate unit with leaks, frayed, kinked hoses or tubing. Repair or replace immediately.
12. Use only pipe, hose and fittings rated for maximum pressure or pressure at which pressure relief valve
is set at. When replacing pipe, hose or fittings, use new product.
13. Do not operate a gasoline engine in an enclosed area. Be sure the area is well ventilated.
14. Do not use these pumps for pumping water or other liquids for human or animal consumption.
15. Do not pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc.
Do not use in explosive atmospheres. The pump should be used only with liquids
compatible with the pump component materials.
16. Be sure all exposed moving parts are guarded and that all coupling devices are securely attached
before applying power.
17. Before servicing, disconnect all power, make sure all pressure in the system is relieved, drain all liquids
from the system and flush.
18. Protect pump from freezing conditions by draining liquid and pumping rust inhibiting antifreeze solution
through the system, coating the pump interior.
19. TRANSPORT - Machine must be stopped to raise or lower booms. Because of cam system, if booms
areraised in transit they canfallforwardor backward when coming to astoporwhile traveling on uneven

SETUP
TheModel1760 Prime Mover arrives from setup and ready for service. Depending on freightcondi-
tions the tires, wheels and steering wheel may need to be installed.
The spray system is normally shipped attached to the 1760 Prime Mover. If a spray system is to be retrofitted to
a 1760 Prime Mover by a dealer or owner, assemble and attach the components in accordance with the parts
drawingsinthe Spray Star 1760 Parts/Service Manual.
1. Removethetop and sides from the shippingcratethenremovethe banding from the Spray Star.
Banding is under tension.
2. Lift front end using a hydraulic jack, taking care that the jack is not placed in a
location that would damage any steering system components, install front
wheels and torque nuts to 64-74 ft/lb (87-100 Nm). Then raise rear axle using a
hydraulic jack and install rear wheels and tires, torque lug nuts to 64-74
ft/lb(87-100Nm).Torque again afterthe first 10 hours and every 200
hoursthereafter.
3. Set park brake.
4. Check the tire pressure. The front tires are 20 psi (1.4 bar) and the rear
tires are 18 psi (1.3 bar).
5. Remove the tape holding woodruff key (Ref B) to the shaft. Put steering
wheel (RefA) on the shaft of the steering mechanism (Ref C).Tighten nut
to 30-40 ft/lb (41 - 54 Nm). Do not over tighten.
6. Install the seat with the stud going through the engine cover and the flat washers, lock washers and nuts.
Use the front set of holes for shorter drivers and use the back set of holes for taller drivers.
7. Besurebattery(automotive type 24F-12 volt; 575 coldcranking
AMPS minimum; 10.25" (260 mm) long x 6.88" (175 mm) wide x
10" (254 mm) high maximum case) is installed in proper position
in the battery box, which is located on the left side of the engine
compartment. Battery posts should be to the rear. This is a
negativegroundingsystem.
Connecting battery cables to the wrong post could
result in personal injury and/or damage to the electri-
cal system. Make sure battery and cables do not inter-
fere or rub on any moving part. Connect red positive (+)
cable (A) to battery first. When disconnecting remove
black negative (-) cable (B) first.
8. Check the engine oil and add as necessary. The dip stick is located in cutout hole behind the seat on the
left side. Oil fill is located on top of valve cover, use SAE 10W-40API Service SJ or higher motor oil. DO
NOT OVERFILL.
9. Fill fuel tank, located on right side, with Unleaded 87 Octane gasoline (minimum).
Gasoline is flammable, caution must be used when storing or handling it. Do not fill fuel tank
while engine is running or an enclosed area, fumes are explosive and dangerous to inhale. DO
NOT SMOKE while filling the fuel tank. DO NOT OVERFILL.

10. Checkbrakefluidinmastercylinder by removing round plug onfloorboard.Add brakefluidifnecessary.
DOT3.
11. Check hydraulic fluid. The hydraulic power unit is located between the engine and the spray tank on the
left hand side. Remove breather plug and add SAE 10W-40API Service SJ or higher motor oil if necessary.
Fluid level should be about 1.5" (38 mm) below top of tank when cold.
12. Check the transmission fill plug on the right hand side of the transmission and check the rear axle fill plug
located on the back side. They should be filled with SAE 80W-90 Gear LubeAPI Service GL-5, GL-4 so
that the level is even or a little below the bottom of the fill hole.
13. Machine should be greased before starting,refertoSprayStar1760Parts/ServiceManualfor location.
14. Attach the Spray Boom and any other Optional Equipment to the Prime Mover, in accordance with instruc-
tions in the Spray Star 1760 Parts/Service Manual. The nozzles must be the correct distance above the
turf as described in SprayingProcedureof thismanual.Thesprayboom must operate properly andthe
outer sections must break away safely if an object is struck by them, they must then return to normal
operationposition.
15. Be sure to double check boom heights, nozzle spacing and displacement before spraying.
16. Fill tank with water and retighten the four bolts used to hold the tank in place.
17. Read operating instructions before starting.
Never allow pump to run dry! The valve on the suction side of the pump (between the pump
and tank) must be fully open whenever the pump is operated.
DAILYCHECKLIST
1. Check park brake adjustment.Adjust as required.
2. Checkengineoillevel.Add as needed. DO NOT OVERFILL.
3. Tire pressure should be 20 psi (1.4 bar) front and 18 psi (1.3 bar) rear maximum.
4. Inspect electrical system for loose connections or frayed wiring, including battery cables. Replace any
faultyequipment or tighten if loose.
5. Check hardware for loose or missing nuts, bolts, screws, etc., and tighten or replace as needed.
6. Inspect hydraulic lines for damage or leaks. Never use hands to inspect leaks.
7. Checkbrakefluidin master cylinder by removing roundplugonfloorboard.Add DOT3brakefluidif neces-
sary.
8. Check hydraulic fluid. The hydraulic power unit is located between the engine and the spray tank on the
left side. Remove breather plug and add SAE 10W-40API Service SJ or higher motor oil if necessary. Fluid
level should be about 1.5" (4 cm) below top of tank when cold.
9. Check the transmission fill plug on the right side of the transmission and check the rear axle fill plug
located on the back side. They should be filled with SAE 80W-90 Gear LubeAPI Service GL-5, GL-4 so
that the level is even or a little below the bottom of the fill hole.
