If the machine is equipped with proportional pressure control, the high pressure
adjustment is made from the Pressure Control Screen on the control panel. Refer to
Section 4, Operation, for additional information.
From the Run Screen, press the tool icon to go to the Main Menu. Select Pressure Control
to display the Pressure Control Screen. The dial on the right of the Pressure Control
Screen indicates the high pressure setting. Press the ▼ arrow to set the pressure to zero.

8. Check the motor rotation. Press the START button on the Run Screen and observe the
pressure gauge on the hydraulic manifold. If the motor rotation is correct, pressure will
begin to build in just a few seconds. If the rotation is not correct, the gauge will not move.
If the motor shaft is rotating in the wrong direction, press the STOP button and turn the
control power off by pressing the
EMERGENCY STOP button.
The electrical power phase must be reversed to any two motor leads. The leads can be
reversed at the disconnect/circuit breaker on the enclosure door, or at the main power
disconnect.
Do not allow the motor to run backward. Incorrect motor rotation will result in
damage to the hydraulic pump.
9. If the unit is equipped with an oil-to-air heat exchanger, check the fan motor rotation.
When viewed from the motor end, the fan should rotate clockwise. If the rotation is not
correct, the electrical power phase must be reversed to any two motor leads. The leads
can be reversed at the junction box on the fan motor or at the electrical enclosure.
10. Remove the cutting orifice and open the nozzle valve.
11. Activate the control power and press the
START button to start the motor. The dump valve
will open for a short time to allow trapped air to bleed from the high pressure cylinders.
Run the machine in low pressure for approximately five minutes with the orifice removed
to purge the system.
12. Check for any leaks in the plumbing, or around the high pressure cylinders. If leaks are
detected, stop the machine and correct any problems.
