5. Turn the Spray Pro selection dial to the Application
Rate position and use the application rate switch to
achieve the desired rate. To do this:
A. Ensure the pump is On.
B. Select the desired gear range and begin driving.
C. Verify the monitor displays the correct application
rate. If needed, manipulate the application rate
switch is until the monitor displays the desired
application rate.
D. Return to the location where spraying is to begin.
6. Set the master boom switch to the On position to
begin spraying.
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 disengage
the PTO lever.

Spraying 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 lock 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.
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 handle to drain any unused material
from the tank and dispose of it according to local codes
and the material manufacturer's instructions.
The tank drain handle is located on top of the tank
(Figure 41).

Using the Tank Drain Handle
A. Loosen the plastic nut at the base of the handle.
B. Pull up on the T-handle until the desired drain
flow is achieved.
Important: Pull the handle gently. Do not
pull too hard or you may damage the tank
drain components.
C. Tighten the plastic nut lock at the base of the
handle lock the tank drain in the open position.
D. When the tank has drained, loosen the plastic nut
and push the T-handle down until it stops.
E. Tighten the plastic nut to secure the tank drain
in the closed position.
Note: The plastic nut on the tank drain should
be tightened when not in use to prevent leaks at
the drain handle.
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 shift lever in the Neutral position, engage the
PTO, and set the hand throttle.
6. Ensure that the agitation control valve is in the On
position.
7. Set the master boom switch and boom control switches
to the On positions to begin spraying.
8. Allow all of the water in the tank to spray out though
the nozzles.
9. Check the nozzles to ensure that they are all spraying
correctly.
10. Set the master boom switch to the Off position,
disengage the PTO, and stop the engine.
11. Repeat steps 3 through 10 at least 2 more times to
ensure that the spray system is fully cleaned.
