1. Knob (section-bypass
valve ) 2. Actuators (section valve)
Boom-Section-Bypass Valve
The boom bypass redirects the fluid flow for a boom section
to the tank when you turn off the boom section. You can
adjust the boom bypass to ensure that the boom pressure
remains constant no matter how many booms sections are on.
Refer to
Adjusting the Master-Boom-Bypass Valve (page 52) .
Agitation Valve
This valve is located on the rear of the tank ( Figure 105 ).
When agitation is on, the flow is directed through the
agitation nozzles in the tank. When agitation is off, the flow
is directed through the pump suction.
Agitation Throttle Valve
The agitation throttle valve is used to reduce the flow available
for the agitation circuit. It provides additional flow for the
boom sections.
Operation
Calibrating the
Boom-Section-Bypass Valves
Note:
Before using the sprayer for the first time, if you
change the nozzles, or as needed, calibrate the sprayer flow,
speed, and boom bypass.
Select an open flat area to perform this procedure.
1. Fill the spray tank halfway with clean water.
2. Lower the sprayer booms.
3. Move the range selector to the N
EUTRAL
position and
set the parking brake.
4. Set the 3 boom switches to the O
N
position, but leave
the master-boom switch off.
5. Set the pump switch to the O
N
position, and turn on
the agitation.
6. Press down on the accelerator pedal until you reach the
maximum engine speed, and toggle the throttle lock
switch to the O
N
position.
7. On the InfoCenter, navigate to the Calibration menu
and select Test Speed.
Note:
Selecting the Home Screen icon at any time
cancels calibrations.
8. Using the plus (+) and minus (-) symbols, enter a test
speed of 5.6 km/h (3.5 mph), then select the Home
icon.
9. Turn the supervisor (rate-lockout) switch to the
U
NLOCK
position, and turn the master-boom switch
to the O
N
position.
10. Using the application-rate switch, adjust the application
rate according to the table below.

11. Turn off the left boom and adjust the boom-bypass
knob (
Figure 107 ) until the pressure reading is at the
previously adjusted level (typically 2.75 bar or 40 psi).
Note:
The numbered indicators on the bypass knob
and needle are for reference only.
