5.0 OPERATION (continued)
5.4 START UP PROCEDURES
5.4.1 Procedure for First Time or Different Electrical Supply ONLY
Phase Monitor (Options H

J Only): Check that the phase monitor light on the
instrument panel is not illuminated. If the light is illuminated, change any two of the three
input leads at the plug. Once the phase monitor light is not illuminated with power
attached, check for proper motor rotation.
a. Remove the pump/motor coupling guard. Reference
Figure 5.4.1

Pump/Motor Coupling Access .
Rotating Parts! Keep hands, feet, hair, and clothing away from all
moving parts to prevent injury. Never operate the HPU with covers,
shrouds, or guards removed.
Electrical Shock!
Never touch electrical wires or components while
the HPU is attached to the power source. They can be sources of
electrical shock.
Do not operate HPU with cabinet panels removed.
b. Verify that the unit has been prepared for use by connecting electrical leads and servicing the reservoir. (Reference
section 3.0 Preparation Prior to First Use .)
c. Keeping hands clear of the pump/motor coupling area, momentarily press the start button and immediately press the stop
button.
d. Observe direction of rotation of the pump/motor coupling. When the Operator is facing the front panel, the pump/motor
coupling should be rotating in a clockwise direction.
e. If the pump/motor coupling is rotating in a counter-clockwise direction, change any two of the three leads at the plug.
Observe direction of rotation to verify that pump/motor is rotating in a clockwise direction.
f. Replace the pump/motor coupling guard.
5.4.2
Initial Start Up of the HPU
a. Unit must be prepared per section 3.0 Preparation Prior to First Use and section 5.4.1 First Time or Different Electrical
Supply ONLY before starting the HPU.
b. Operator must be familiar with this manual and be properly trained prior to starting the HPU.
c.
Connect quick disconnects to hose ends or cap the pressure and return hose ends.
d. Place the reservoir selector valve in "HPU Reservoir" position.
e. Place the bypass valve in the "Open" position.
f.
Press the start switch and adjust the flow control until approximately 10 gpm (38 lpm) is displayed on the flowmeter. (If no
flow displays on the flowmeter after adjusting the flow control, reference
Trouble Shooting 8.2 No Flow ).
g. Close the bypass valve, adjust the pressure control until 3,000 psi (206.84 bar) is displayed on the pressure gauge. (If no
pressure displays on the system pressure gauge after adjusting the pressure control, reference Trouble Shooting 8.4 No
Pressure or Reduced Pressure) .
h. Open the bypass valve; press the stop switch.
NOTE: Maintenance and Trouble Shooting are to be performed by a skilled and trained technician.

PRELIMINARY ADJUSTMENTS FOR OPERATION
The following are basic to the operation of the HPU and should be thoroughly understood. The pressure and flow controls
have lock nuts to prevent rotation of the control shaft during operation. These nuts should be moved away from the pump
during adjustment of flow or pressure in order to eliminate binding of the control shafts.
5.5.1
Flow Control Adjustment
a. Open bypass valve.
b. Select "Hydraulic Power Unit" position with reservoir selector valve.
c.
Start HPU.
d. Adjust flow control on pump for maximum desired flow. Observing the flowmeter, read flow in gallons (liters) per minute
directly from flowmeter. Be sure the control shaft lock nut is loose during adjustment. Tighten after adjustment to maintain
setting.
