chemical manufacturer.
3. Open the lid on the spray tank.

before adding it to the tank
9. Add the remaining water to the tank.
Applying Chemicals
Important In order to ensure that your solution remains
well mixed, use the agitation feature whenever you have
solution in the tank. For agitation to work, the pump must
be on and the engine must be running above an idle. If you
stop the vehicle and need agitation on, place the range
selector in the Neutral position, set the parking brake, press
the accelerator pedal to the floor, and turn the neutral
engine speed control on.
Note: This procedure assumes that the pump is on from the
Filling the Spray Tank procedure.
1. Swing the booms into position.
2. Set the master boom switch to the Off position. The
Spray Pro monitor will display “HOLD.”
3. Set the individual boom switches, as needed, to the On

4. Drive to the location where you will be spraying.
5. Turn the Spray Pro selection dial to the Application
Rate position and use the application rate switch to

Note: When the tank is nearly empty, the agitation may
cause foaming in the tank. In this case, turn the agitation
control valve to the 3 o’clock position to turn it off.
Alternatively, you can use an anti-foaming agent in the
tank.
7. When finished spraying, set the master boom switch to
the Off position to turn off all booms, then set the pump
switch to the Off position.
Operating Tips
• Do not overlap areas that you have previously sprayed.
• Watch for plugged nozzles. Replace all worn or
damaged nozzles.
• Use the master boom switch to stop the spray flow
before stopping the sprayer. Once stopped, use the
neutral engine speed control to hold the engine speed up
to keep the agitation running.
• You will obtain better results if the sprayer is moving
when you turn the booms on.
• Watch for changes in the application rate that may
indicate that your speed has changed beyond the range
of the nozzles or there is a problem with the spray
system.
Cleaning the Sprayer
Important You must always empty and clean the
sprayer immediately after each use. Failure to do so may
cause the chemicals to dry or thicken in the lines, clogging
the pump and other components.
Note: To automate this process, install the optional Rinse
Kit.
1. Stop the sprayer, set the parking brake, place the range
selector in the Neutral position, and turn off the engine.
2. Use the tank drain knob to drain any unused material
from the tank and dispose of it according to local codes
and the material manufacturer’s instructions.
3. Fill the tank with at least 50 US gallons (190 L) of clean
fresh water and close the cover.
Note: You can use a cleaning/neutralizing agent in the
water as needed. On the final rinse, use only clean, clear
water.
4. Start the engine.
5. With the range selector in the Neutral position, press the
accelerator pedal to the floor and set the neutral engine
speed control switch to the On position.
6. Ensure that the agitation control valve is in the On
position.
