OPERATING INSTRUCTIONS
Before operating the Spray Star 1600P, become familiar with all controls and functions. Also complete all maintenance requirements and read all safety warnings. Knowing the Spray Star 1600P thoroughly, how it operates, and by doing the prescribed maintenance steps, you can expect trouble free operation for years to come.
SAFETY
Safety needs to always be the concern of an operator of a moving vehicle or any machine with moving parts.
1. Keep all shields and guards in place.
2. Keep the parking brake engaged any time the operator is away from the vehicle or whenever service is performed.
3. Always wear the necessary protective clothing and equipment.
4. Turn engine off when refueling or performing maintenance not specifically requiring engine power.
STARTING THE ENGINE
1. Make sure the fuel flow valve is ‘On’. It is located on the fuel tank.
2. Make sure the spray pump is disengaged.
3. Depress the clutch pedal to activate the interlock switch.
4. Place shift lever in neutral.
5. The ignition switch is located to the right of the steering column. Insert the key (A) and turn clockwise until the engine starts (C). Release the key and it will return to the run position (B). Use the choke and hand throttle as necessary.
6. Allow engine to idle and warm up before selecting direction of travel.
7. Make sure the park brake is disengaged.
STOPPING THE ENGINE
If the engine has been running under high power, let it run at slow idle speed a few minutes to cool the engine down, before turning the ignition switch to the OFF position.
1. Disengage spray pump.
2. Move the throttle lever to “slow” and turn ignition key to the “off” position.
3. Remove the ignition key and engage the park brake.
Never leave the vehicle unattended with the engine running. Always bring the vehicle to a complete stop, engage park brake, turn key off and remove key.

OPERATING INSTRUCTIONS
(CONTINUED)
Before using the Spray Star, the operator or spray technician must familiarize themselves with all of the information on chemical spraying contained in Spraying Procedure of this manual.
All testing and calibration of sprayers is to be done with water, not chemicals. This insures the safety to all involved in performing the calibration operation. Only after all calibration procedures are completed should chemical be added to the sprayer.
OPERATION OF THE 3-SPEED TRANSMISSION
The transmission provides 3 forward speeds and reverse. The operator selects the speed (gear) in which he or she wishes to operate depending on the ground speed desired. The Spray Star can be started and operated in any speed. It is not necessary to start in low gear.

4-10 m.p.h. (6-16 kph)
0-3 m.p.h. (0-5 kph)
Select the gear desired by moving the shift lever located at the operator’s right side to the point indicated by the shift pattern found on the shift knob.
Spraying should be done in the lowest gear possible that will provide the desired ground speed. This will maximize pump performance and minimize ground speed variance due to uneven terrain.
GROUND SPEED CONTROL
1. Select the gear to be used.
2. Place the Ground Speed Control lever to fast.
3. Start the vehicle and engage the clutch to begin moving.
4. Push the foot accelerator fully to the floor.
5. While the foot accelerator is fully depressed, begin moving the Ground Speed Control lever towards slow until the correct operating speed is attained.
6. The desired speed will be maintained as long as the foot accelerator is fully depressed.
7. Vehicle will return to the established ground speed whenever the foot accelerator is fully depressed unless the Ground Speed Control lever has been moved to a different setting.
8. To operate the Spray Star at higher speed for transport, the Ground Speed Control lever should be returned to the fast position.
HAND THROTTLE CONTROL LEVER
Transmission must be in neutral and park brake set when engine throttle control is used.
To increase the engine speed without holding your foot pedal down, use the engine throttle control lever on the right hand control panel. Push the lever forward until the desired rpm is attained.
This procedure will set the RPM allowing the operator to use the remote hose and handgun. It will also permit the operator to check the operation of the spray boom by observing it from the rear of the vehicle.
To release throttle control, pull back on the Lever allowing the engine to return to idle.
Transmission must be in neutral and parking brake set when engine throttle control is in use.
Never drive vehicle with engine speed increased by engine throttle lever. Loss of vehicle control may result.
TOWING UNIT
While towing the Spray Star 1600P place shift lever in neutral and disengage park brake.
HILLSIDE OPERATION
Do NOT stop or start suddenly on any slope. Be especially cautious when changing direction. Do NOT operate vehicle on slopes greater than 20°.

SPRAYER VALVE SETTINGS AND SPRAY TANK AGITATION
The gate valve on the suction side of the pump, between the tank and the pump must be open before pump is engaged. Close this valve only when necessary to clean the filter with spray material in the spray tank.
There is one manual flow control valves on the discharge side of the spray system. This valve controls the agitator. This valve may be opened as much as necessary to provide hydraulic agitation through the quadrajet agitator in the tank bottom. This valve may be partially closed to prevent or reduce foam buildup from the spray materials inside the tank. When the liquid level in the spray tank reaches a certain level (usually 1-25 gallons
(3.8-95 Liters) depending on terrain and other conditions) it may be necessary to close the valve in the agitator line in order to prevent loss of suction prime.
If your Spray Star is fitted with a hose reel, there is a second ball valve on the discharge system to supply material to the hose reel.
The Quadrajet agitation system operates with four venturi jets in the tank bottom. These jets have replaceable orifice discs which discharge the following amounts of spay material.

You can change orifice disc sizes to enhance spray system performance. Smaller discs reduce amount of agitation (desirable in some foaming materials) and make more dischargeable liquid available for nozzles. Larger
(or none) discs increase amount of agitation and make less dischargeable liquid available for nozzles.
