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.
Agitation Control Valve
This valve is located on the right side of the tank
(Figure 19). 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.
