Boom Bypass Valves
The boom bypass valves redirect the fluid flow for a boom
to the tank when you turn off the boom section. You can
adjust these valves to ensure that the boom pressure
remains constant no matter how many booms are on. Refer
to Adjusting the Boom Bypass Valves, page 20.
Pressure Gauge
The pressure gauge is located on the dash (Fig. 13). This
gauge shows the pressure of the fluid in the system in psi
and kPa.
Pump
The pump is located near the back of the tank on the left
side (Fig. 22).

Tank Cover
The tank cover is located in the center of the top of the tank
(Fig. 23). To open it, turn off the engine, then turn the front
half of the cover to the left and swing it open. You can
remove the strainer inside for cleaning. To seal the tank,
close the cover and rotate the front half toward the right.
Anti-siphon Fill Receptacle
To the front of the tank cover is a hose receptacle with a
threaded fitting and a 90 degree barbed fitting and tube
which you can direct toward the tank opening (Fig. 23).
This receptacle allows you to connect a water hose to it and
fill the tank with water without contaminating the hose with
the chemicals in the tank.
Adjusting the Boom Bypass
Valves
Important If you have the Pro Control
installed, the boom valves must be closed.
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. Move the throttle lever to the Spray position.
5. Set the pump switch to the On position to start the
pump.
