Board section.

PRESSURE CALIBRATION ON
ELECTRICAL BOARD

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 output of pump between
fluid pump and airless hose to
monitor Fluid Pump Pressure.

3. Start engine and run at maximum

RPM. Turn Prime/Pressure Relief
Valve to the open (Prime) position.
Turn Pressure Control Knob to
maximum position (fully clockwise).

4. Using an insulated screwdriver,

adjust "Pressure Calibration"
Trimpot by turning clockwise until
the clutch engages. When the
clutch engages the pump will
commence Priming. When pump is
primed, turn the Prime/Pressure
Relief 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
(when using a 3/8" hose), the clutch
will engage and build pressure to
3000 psi and disengage. Trigger
gun several times to ensure proper
pressure setting.

6.  Turn Pressure Control Knob to

minimum position. The clutch
