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
applyingpower.
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 transitthey canfall forward orbackward when coming to astop or whiletraveling onuneven

SETUP
TheModel 1760Prime Moverarrives from setupand readyfor service. Dependingon 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
drawingsin theSpray Star 1760Parts/Service Manual.
1. Removethe top and sides fromthe shippingcrate then removethe bandingfrom the SprayStar.
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 (87-100 Nm). Torque again after the first 10 hours and
every 200 hours thereafter.
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. Be sure battery (automotive type 24F-12 volt; 575 cold cranking
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
negative grounding system.
Connecting battery cables to the wrong post could
result in personal injury and/or damage to the electrical
system. Make sure battery and cables do not interfere 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.

SETUP (CONTINUED)
10. Checkbrake fluid inmaster cylinderby removing roundplug onfloorboard.Addbrake fluidif necessary.
DOT 3.
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-40 API Service SJ or higher motor oil if neces-
sary. 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 Lube API Service GL-5, GL-
4 so that the level is even or a little below the bottom of the fill hole.
13. Machine shouldbe greasedbefore starting,refer to SprayStar1760 Parts/ServiceManualfor location.
14. Attach the Spray Boom and any other Optional Equipment to the Prime Mover, in accordance with
instructions in the Spray Star 1760 Parts/Service Manual. The nozzles must be the correct distance
above the turf as described in Spraying Procedure of this manual. The spray boom must operate
properly and the outer sections must break away safely if an object is struck by them, they must then
return to normal operation position.
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. Check engine oil level. 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
faulty equipment 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. Check brake fluid in master cylinder by removing round plug on floorboard. Add DOT 3 brake fluid if
necessary.
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 Lube API Service GL-5, GL-4 so
that the level is even or a little below the bottom of the fill hole.
10. Inspect steering, throttle and shift linkages for good hookups and clear travel.
11. Check anti-vibration mounts on engine frame.
12. Check controls for smooth, proper working operation. Lubricate as needed.
