Introduction
OPERATING INSTRUCTIONS
(CONTINUED)
Before using the Spray Star, the operator or spray technician must familiarize themselves with all of the infor-
mation 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 proce-
dures are completed should chemical be added to the sprayer.
GROUND SPEED CONTROL
1. Select the gear to be used.
2. Place the Ground Speed Control lever to fast.
3. Push the foot accelerator fully to the floor.
4. While the foot accelerator is fully depressed, begin moving the Ground Speed Control lever towards slow
until the correct operating speed is attained.
5. The desired speed will be maintained as long as the foot accelerator is fully depressed.
6. 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.
7. 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
Park brake must be 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.
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°.
TOWING UNIT
When it is necessary to move the Spray Star 1600H without the engine running, the bypass valve built into
hydrostatic pump must be "open" by turning it counterclockwise. The valve is located on the bottom of the
pump. An "open" valve allows fluid to pass through the wheels freely. When normal driven operation is desired,
valve should be "closed" by turning it clockwise. Failure to "close" the valve with engine running means no
power to wheels.
