Boom Bypass Valves
The boom bypass valves redirect the fluid flow for a boom
to the tank when you turn off the boom section. They are
located at the bottom of each boom valve 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 on page 23.
Note: If you use the Pro Control, you must shut all the
bypass valves.
Pressure Gauge
The pressure gauge is located on the dash (Fig. 11). 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. 24).

Tank Cover
The tank cover is located in the center of the top of the tank
(Fig. 25). 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° barbed fitting and tube which you
can direct toward the tank opening (Fig. 26). 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.
