Sonic Boom and Foam Marker Switch
Locations (Optional)
If you install the sonic boom and/or the foam marker kit, you
will add switches to the control panel for controlling their
operation. The sprayer comes with plastic plugs in these
locations.
Regulating (Rate Control) Valve
This valve, located behind the tank (Figure 34), controls the
amount of fluid that is routed to the booms by directing
fluid flow to the booms or the bypass hose to the agitation
valve. You can control this valve in two ways: the application
rate switch or manually. To control it manually, you need to
disconnect the wire connector on the valve, then you can
rotate the knob on top of the valve to manually obtain the
desired application rate.

Flowmeter
The flowmeter measures the flow rate of the fluid for use by
the Spray Pro™ system (Figure 34).
Boom Valves
These valves turn the three booms on or off (Figure 34). If
you do not have a boom installed or do not want a boom
to be able to be turned on, you can manually operate each
valve by disconnecting the wire connector in the valve, then
rotate the knob on the valve clockwise to turn the valve off or
counterclockwise to turn it on.
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
Calibrating the Boom Bypass Valves, in the Operation section.

Agitation Control Valve
This valve is located on the right side of the tank (Figure 35).
Turn the knob on the valve to the 9 o'clock position to turn
on the tank agitation and to the 3 o'clock position to turn
off the tank agitation.
1. Agitation control valve
Note: For agitation to work, the PTO and clutch must be
engaged, and the engine must be running above an idle. If
you stop the sprayer and need agitation on, place the range
shift lever in the Neutral position, let out the clutch, set the
parking brake, and set the hand throttle (if equipped).
Pressure Gauge
The pressure gauge is located to the right of the tank
(Figure 35). This gauge shows the pressure of the fluid in the
system in psi and bar.
Tank Drain Handle
The tank drain handle is located on top of the tank (Figure 36).
To open the tank drain, loosen the nut and pull upwards on
the T-handle until the desired drain flow is achieved.
Important: Pull the handle gently. Do not pull too hard
or you may damage the tank drain components.
Tighten the plastic nut lock at the base of the handle lock the
tank drain in the open position. When the tank has drained,
loosen the plastic nut and push the T-handle down until it
stops. Tighten the plastic nut to secure the tank drain in the
closed position.
Note: The plastic nut on the tank drain should be tightened
when not in use to prevent leaks at the drain handle.
