15.
When the distance value is displayed, use the [+] or [–]
buttons to change it to 500 feet.
16.
When the display begins alternating again, the speed
calibration value will have changed; write this number
down and save it. This is the calibration value for your
sprayer.
17.
Press [CAL] until the red light turns off. You can also
exit calibration mode by driving the sprayer.
Resetting an OFL Condition
If the monitor reads “OFL,” it indicates that you have
exceeded the monitor screen dimensions. Press and hold
[RESET] to set the display to 0.
Adjusting the Boom Bypass
Valves
After you install your booms and nozzles and before using
the sprayer for the first time, adjust the boom bypass valves
so that the pressure and application rate remains the same
for all booms when you turn one or more booms off.
Select an open flat area to perform this procedure.
1.
Fill the spray tank with clean water.
2.
Put the extension booms down, if installed.
3.
Set the parking brake and start the engine .
4.
Set the dial on the Spray Pro monitor to Application
Rate.
5.
Place the range selector in the Neutral position.
6.
Press the accelerator to the floor and set the neutral
engine speed control switch to the On position.
7.
Set the pump switch to the On position to start the
pump.
8.
Set all three boom switches and the master boom switch
to the On position.
9.
Use the application rate switch to adjust the pressure as
read on the pressure gauge until it is in the range for the
nozzles you installed on the booms (typically 50 psi).
10.
Record the reading on the pressure gauge.
11.
Turn off one of the booms using the appropriate boom
switch.
12.
Adjust the boom bypass valve (Fig. 28) under the boom
control valve for the boom you turned off until the
pressure reading on the gauge is the same as it was in
step 9.

13.
Turn the boom on.
14.
Repeat steps 11 through 13 for the other booms.
15.
Drive the sprayer at the desired speed while spraying
and turn each boom off individually. The pressure on
the gauge should not change much.
Operating the Sprayer
To operate the sprayer you first fill the spray tank, then
apply the solution to the work area, and finally clean the
tank. It is important that you complete all three of these
steps in succession to avoid damaging the sprayer. For
example, do not mix and add chemicals in the spray tank at
night and then spray in the morning. This would lead to
separation of the chemicals and possible damage to the
sprayer components.
Chemicals are hazardous and can cause personal
injury.
•
Read the directions on the chemical labels
before handling the chemicals and follow all
manufacturer recommendations and
precautions.
•
Keep chemicals away from your skin. Should
contact occur, wash the affected area thoroughly
with soap and clean water.
•
Wear goggles and any other protective
equipment recommended by the chemical
manufacturer.
Caution
Filling the Spray Tank
Important
Ensure that the chemicals you will be using
are compatible for use with Viton (see the manufacturer’s
label; it should indicate if it is not compatible). Using a
chemical that is not compatible with Viton will degrade the
o-rings in the sprayer, causing leaks.
