Knob and remove knob.

1. Turn "Pressure Calibration" Trimpot adjustment on

electrical control board in the counter clockwise direction

at least 15 revolutions.

2. Connect 5000 psi glycerine pressure guage on outlet of

pump between fluid pump & airless hose to monitor Fluid

Pump Pressure.

3. Start engine and run at maximum RPM. Turn Prime

Valve to the open (Prime) position. Turn Pressure

Control Knob to maximum position (fully clockwise).

5. Using a 1/2" nutdriver or 1/2" deep socket, remove nut

will commence Priming. When pump is primed, turn

the Prime Valve to the Closed (Pressure) Position.

THE PUMP WILL BEGIN TO PRESSURIZE AND THE

CLUTCH WILL DISENGAGE AT A LOW PRESSURE.

CONTINUE TURNING THE TRIMPOT CLOCKWISE

TO INCREASE PRESSURE TO 3000 PSI.

5. Trigger gun. The pressure should drop approximately

350-400 psi, the clutch will engage and build

pressure to 3000 psi and disengage. Trigger gun

several times to ensure proper pressure setting.
