Agitation Adjustment
The agitation valve is used to adjust the pressure to the
agitation nozzles in the tank. Refer to the agitation gauge,
and adjust the pressure to a desired rate. Different chem-
icals require different agitation pressures to keep the
chemical in suspension.
!
CAUTION!
If using liquid fertilizer or any other chemical that will corrode
brass, install a gauge protector under the brass agitation gauge
or plug the gauge hole. Failure to do so will eventually cause the
gauge to fail and chemical to be expelled from the gauge.
Agitation Adjustment with Tank Rinse
(Optional Equipment)
Refer to Figure 19
The agitation is adjusted the same way when the sprayer
has the Tank Flush option. The only difference is the
plumbing to adjust it. Rotate the agitation valve to achieve
the desired pressure on the agitation gauge.
Pressure Adjustments
(Manual Control System Only)
One of the most important areas of controlling the sprayer
accuracy is to have the proper pressure when spraying.
The pressure is determined when the sprayer is calibrat-
ed. Refer to Calibration Procedures in the Application
Guide.
The electric ball valve is used to adjust the pressure to the
booms. It is controlled with the pressure adjust switch on
the control box. The boom pressure is displayed by the
boom pressure gauge.
To adjust the pressure, hold the pressure adjust toggle
switch up for more pressure, down for less pressure.
As the tank level decreases, the boom pressure may
change. Check boom pressure gauge frequently and
make sure that the pressure doesn’t change. Generally,
the boom pressure will need to be adjusted up slightly
when the tank level decreases.

Refer to Figure 20
When the manual pressure adjustment valve is wide open,
the pressure adjust switch is very sensitive. To decrease
the sensitivity of the pressure adjust, set the manual pres-
sure adjustment valve. Refer to Manual Pressure Valve in
the “Operating Instructions” section on page 16.
