Pressure Gauge
The pressure gauge ( Figure 14 ) is located on the
dash. This gauge shows the pressure of the fluid in
the spray system in psi and kPa.
Spray-Mode Switch
Use the spray-mode switch to change between the
application rate mode (closed loop) and the manual
mode (open loop).
Application-Rate Switch
The application-rate switch is located on the dash
to the right of the steering wheel (
Figure 14 ). Use
the application-rate switch to control the spray pump
speed when operating the sprayer in the manual
mode. Press and hold the switch forward to increase
the application rate (pressure), or press and hold it
rearward to decrease the application rate (pressure).
Spray-Pump Switch
The spray-pump switch is located on the center
console to the right of the seat (
Figure 14 ). Toggle this
switch forward to run the spray pump or rearward to
stop the pump. When the switch is turned on, a light
on the switch illuminates.
Important:
Engage the spray-pump switch only
when the engine is at
LOW IDLE
to avoid damaging
the pump drive.
Boom-Section Lift Switches
The boom-section lift switches are located on the
center console to the right of the seat and used to
raise or lower the left and right boom sections (
Figure
14 ).
Master Section Switch
The master section switch is located on the center
console of the machine. The switch allows you to
start or stop the spray operation. Press the switch to
enable or disable the spray system (
Figure 14 ).
Left, Center, and Right Section Switches
The 3 section switches are located on the center
console in the front of the armrest (
Figure 14 ). Toggle
each switch forward to turn the corresponding section
on and rearward to turn each off. When the switch is
in the O
N
position, an icon appears at the top of the
InfoCenter.
Note:
These switches affect the spray system only
when the master section switch is in the O
N
position.
Agitation Switch
The agitation switch is located on the center console
to the right of the seat (
Figure 14 ). Toggle this switch
forward to turn on the agitation in the tank or rearward
to stop the agitation. When the switch is turned on, a
light on the switch illuminates. To operate the agitation
function, you must run the sprayer system pump and
you must run the engine above low idle.
Agitation-Bypass Valve
The agitation-bypass valve redirects the flow of fluid
to the sprayer-system pump when you turn off the
agitation function (
Figure 15 ). The agitation-bypass
valve is located above the agitation valve. You can
adjust the bypass valve to ensure that the pressure
remains constant when cycling agitation on or off; refer
to
Calibrating the Agitation-Bypass Valve (page 39) .
