Rate Lockout Key Switch
The rate lockout key switch is located on the control
panel to the right of the seat (Figure 16). 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.
Regulating (Rate Control) Valve
This valve, located behind the tank (Figure 17), 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.

Flowmeter
The flowmeter measures the flow rate of the fluid for
use by the Spray Pro™ system (Figure 17).
Boom Valves
These valves turn the three booms on or off (Figure 17).
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 18). 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 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.
