Application Rate Switch
The application rate switch is located on the left side of
the control panel (Fig. 25). Press and hold the switch
upward to increase the spray system application rate, or
press and hold it downward to decrease application rate.
Rate Lockout Key Switch
The rate lockout key switch is located on the lower, left
corner of the control pane (Fig. 25). 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.
Boom Lift, Sonic Boom, and Foam
Marker Switch Locations
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 (Fig. 26), 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 (Fig. 26).
Boom Valves
These valves turn the three booms on or off (Fig. 26). 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 (Fig. 26) 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 Adjusting the Boom Bypass
Valves, page 26.
Agitation Control Valve
This valve is located on the right side of the tank
(Fig. 27). 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
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).
