1. Agitation control valve
Note: For agitation to work, the pump must be on
and the engine must be running above an idle. If you
stop the sprayer and need agitation on, place the range
selector in the Neutral position, set the parking brake,
press the accelerator pedal to the floor, turn the pump
On and turn the neutral engine speed lock On.
2. Pressure gauge
Pressure Gauge
The pressure gauge is located to the right of the tank
(Figure 19). This gauge shows the pressure of the fluid
in the system in psi and kPa. Use the gauge to adjust the
by-pass valves whenever you change nozzles.
Anti-siphon Fill Receptacle
To the front of the tank cover is a hose receptacle with a
threaded fitting, a 90 degree barbed fitting, and a short
hose which you can direct toward the tank opening. 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.
Important: Do not lengthen the hose to allow
contact with the tank fluids.
