OPERATION
OVERVIEW
The pumping system draws solution from the tank,
through the suction hose and into the pump. The
pump forces the solution under pressure through the
pump manifold, where it is directed to the spray wand
and (if equipped) the optional spray boom.
Regularly inspect the suction hose strainer inside
the tank. Flush with water to clear any accumulated
debris.

• Current weather and terrain conditions must be
considered when setting up the sprayer.

SPRAY APPLICATION
Spray Wand:
Maximum range 35'.
Accessory Spray Booms
PBA-22:
2-Nozzle Boom, 80" spray width.
PBA-77:
7-Nozzle Boom, 140" spray width.
For application rates, refer to the Accessory Spray
Boom Calibration section of this manual.
OPERATING PRESSURE
Optimal operating pressure is 40 psi. The pump has
a pressure switch that will shut off the pump when
pressure reaches 60 psi.
Typically the spray wand will be operated at between
20 and 40 psi. Refer to the Spray Boom Calibration
section for data on boom operating pressures.
To adjust the system pressure, make sure the wand
(and spray boom, if equipped) are turned OFF. Turn
the pump ON and adjust the BYPASS valve until the
gauge reads 40 psi. The pump will run continuously.
Once the spray wand or boom is activated, the
pressure will drop slightly.
CAUTION
Always use appropriate personal protective
equipment, including gloves and safety
goggles, when filling sprayer.
CAUTION
When using spray wand, never point it at
objects (i.e., humans, vehicles, etc.). Keep at
least 10 feet away from objects while using
the spray nozzle.
CAUTION
Read and adhere to manufacturer's
material package labeling,
including Safety Data Sheet
requirements.
