INITIAL STARTUP
7.
Hydraulic System.
The following procedure should be followed to ensure that the pump unit is not damaged during initial startup:
a. Fill tank to proper level as indicated on the oil level gauge. Disconnect tubing between the pump and
manifold and fill the pump with oil. Reconnect tubing.
b. Remove a plug from the front of a brake valve and install a 0-3000 psi pressure gage.
c. Check direction of motor shaft rotation by starting the motor long enough to determine the direction of
rotation. Ensure that motor rotation is in the same direction as the arrow on the pump. If the motor rotates in the wrong
direction, reverse two of-the motor leads to change the direction of rotation.
