Using Handwash Tank
In the event of an accidental spill of chemicals on skin or in
eyes, use the Handwash Tank to flush away chemicals.
1. Open the tank valve and use the hose to direct the
clean water on all contaminated areas. Wash all con-
taminated areas of skin with soap and water. To flush
chemicals from eyes, point the hose and water stream
upward while lowering eyes into the stream of flowing
water.
2. Close the tank valve and refill the handwash tank with
fresh water when finished.
3. Periodically refill the handwash tank with fresh water.
ALWAYS keep the handwash tank clean.
Agitation
Refer to Figure 9
To adjust the agitation, adjust the Agitation Valve. Refer to
the agitation gauge to set a reference pressure for the ag-
itation.
Manual Pressure Valve
Refer to Figure 9
When the manual pressure valve is wide open, the pres-
sure adjustment can be very sensitive. If sprayer is
equipped with an automatic controller, the butterfly valve
will have to move more often causing additional wear. If
sprayer is equipped with manual controls plumbing, the
pressure adjustment switch on the control box will be more
sensitive and it will be hard to set the pressure. To de-
crease the sensitivity, set the manual pressure adjustment
valve as follows:
1. Open the control valve so that it is wide open and
there is full flow to the sprayer booms. On a sprayer
with manual controls, adjust the pressure switch. On
an automatic controller, open the butterfly valve until it
is full open.

2. Shut the manual pressure adjustment valve down so
the pressure is about 20 PSI greater than the pressure
you will spray at. The pressure the spray will be ap-
plied at is determined when calibrating sprayer. Refer
to the Application Guide.
With this valve set, it will decrease the flow through the
electric ball valve and reduce the sensitivity of the pres-
sure adjustment switch.
Operating Whirlfilter ®
There are two Whirlfilters ® on the Great Plains Sprayer.
One filters the water entering the tank and the other filters
the chemical solution being sprayed.
Refer to Figure 10
Clean-out the solution Whirlfilter ®
1. Fill the sprayer tank with water and turn the pump on.
2. With the pump running, slowly open the clean-out
valve and allow the grit to flow out into a bucket. Clean
out the solution Whirlfilter
® only when the sprayer tank
is filled with water and no chemical has been added.
3. Close the clean-out valve and turn off the pump.
4. Dispose of the grit and water in the same manner de-
scribed on the manufacturer’s label of the latest chem-
ical used in the sprayer.
Clean out the tank-fill Whirlfilter ®
1. Start with an empty sprayer tank.
2. Position a bucket under the plug in the sump of the
Whirlfilter
® and allow the grit to fall out.
3. Screw the plug back in using pipe thread sealant to
seal the plug.
4. Dispose of the grit and water in the same manner de-
scribed on the manufacturer’s label of the latest chem-
ical used in the sprayer.
