3. When the booms need to be retracted, stop the sprayer
on level ground.
4. Use the boom lift switches to raise the booms. Raise
the booms until have moved completely into boom
transport cradle forming the "X" transport position
and the boom cylinders are fully retracted.
Important: To prevent damage to the boom
actuator cylinder, make sure the actuators are fully
retracted before transport.
The Boom Transport Cradle
The sprayer is equipped with a boom transport cradle that
has a unique safety feature. In the event of accidental boom
contact with a low overhead object while in the transport
position, the boom(s) can be pushed out of the transport
cradles. If this occurs, the booms will come to rest in a
near horizontal position to the rear of the vehicle. While
the booms will not be damaged due to this movement, they
should be immediately put back into the transport cradle.
Important: The booms can be damaged by transporting
them in any position other than the "X" transport
position using the boom transport cradle.
To put the booms back into the transport cradle, lower the
boom(s) to the spray position, and then raise the boom(s)
back into the transport position. Make sure the boom
cylinders are fully retracted to prevent actuator rod damage.

Spraying

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,
turn on the pump, and turn the neutral engine speed
lock On.
Note: This procedure assumes that the pump is on from the
Filling the Spray Tank procedure.
1. Lower the booms into position.
2. Set the master spray lever to the Off position.
3. Set the individual boom levers, as needed, to the On
positions.
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
achieve the desired rate. To do this:
Note: The boom by-pass valve must be properly
calibrated for the application rate to be accurate. Refer
to Calibrating the Boom By-Pass Valves.
A. Ensure the master spray lever is Off and the
pump is On.
B. With the brake pressed, select the desired gear
range then begin driving at maximum speed.
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 spray lever 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 (if compatible with the chemical you are
using).
7. When finished spraying, set the master spray lever to
the Off position to turn off all booms, then set the
pump switch to the Off position.

Spraying Tips

•
Do not overlap areas that you have previously sprayed.
•
Watch for plugged nozzles. Replace all worn or damaged
nozzles.
•
Use the master spray lever to stop the spray flow before
stopping the sprayer. Once stopped, place the range
selector in neutral and 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.
Clean the spray system after each spraying session. To
properly clean the spray system:
•
Use three separate rinses.
•
Use a minimum of 50 gallons for each rinse.
•
Use the cleaners and neutralizers as recommended by the
chemical manufacturers.
•
Use pure clean water (no cleaners or neutralizers) for the
last rinse.
The rinse tank is located at the front, right side of the
chemical tank (Figure 24). If you install the optional Rinse
Kit, you can fill this tank with fresh water and automatically
rinse the main tank, boom supply lines and nozzles.
