Pump Switch
The pump switch is located on the control panel
to the right of the seat (Figure 17). Toggle this
switch forward to run the pump or rearward to
stop the pump.
Important: Only engage the pump switch
when the engine is at low idle to avoid
damaging the pump drive.
Application Rate Switch
The application rate switch is located on the
control panel to the right of the seat Figure 17).
Press and hold the switch forward to increase
the spray system pressure, or press and hold it
rearward to decrease pressure.
Rate Lockout Key Switch
The rate lockout key switch is located on the
control panel to the right of the seat (Figure 17).
Turn the key counterclockwise to the locked
position to disable the application rate switch,
thereby keeping anyone from accidentally changing
the application rate. Turn the key clockwise to the
unlocked position to enable the application rate
switch.
Important: Do not attempt to move the
range selector while the rate lockout key is
engaged. Forcing the selector while moving
will damage lockout key components.
Boom Lift
The boom lift switches are used to raise the left
and right boom respectively.
Sonic Boom (Optional)
The Sonic Boom switch is a rocker switch used to
operate the Sonic Boom. Toggle switch forward
for automatic, rearward for manual and center for
Off.
Foam Marker Switch Locations
(Optional)
If you install the electric boom lift, sonic boom,
and foam marker kit, you will add switches to the
control panel for controlling their operation. The
sprayer comes with plastic plugs in these locations.
Rate Control Valve
This valve, located behind the tank (Figure 18),
controls the amount of fluid that is routed to the
booms by directing fluid flow to the booms or
the bypass hose to the tank. 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 pressure.

2. Flowmeter
Flowmeter
The flowmeter measures the flow rate of the fluid
for use by the Spray Pro™ system (Figure 18).
Boom Valves
These valves turn the three booms on or off
(Figure 18). 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.
