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.
Important The boom bypass valves mus be adjusted
any time nozzles are changed or replaced
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. Place the range selector in the Neutral position.
5. Set the hand throttle.
6. Engage the PTO lever to start the pump.
7. Set all three boom switches and the master boom
switch to the On position.
8. 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
40-50 psi).
9. Record the reading on the pressure gauge.
10. Turn off one of the booms using the appropriate boom
switch.
11. Adjust the boom bypass valve (Fig. 31) 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 8.

the gauge should not change.

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.
Caution
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.
