MAINTENANCE
Cleaning Tank and Spray Gun
When spraying is finished rinse the tank with clean water and pump the contents out
through the spray gun. A triple rinse is recommended. The tank may also be drained
by removing the drain plug at the lid end.
Filter Maintenance
After each use or when the tank has been emptied (whichever comes first) it is
recommended that the suction filter located under the white nut at the tank outlet be
removed and cleaned.
Pressure Switch Adjustments
Adjustment should not be necessary under normal operating conditions. Increasing
the pressure setting will not increase pump flow but may reduce pump life. To adjust
the switch, remove the cover from the end of the pump beneath the power switch
and rotate the adjustment screw. Replace the cover after adjustment.

Operate the spray gun to release air from the pump.
