POWER UNIT INSTALLATION & START UP PROCEDURE
Fill the reservoir with automatic transmission fluid or any clean
hydraulic fluid having a viscosity index that is suitable for the
climatic conditions in which the unit will be operated. Recom-
mended operating temperature range is +20° F to +180° F.
GENERAL START UP INSTRUCTIONS
NOTE: The ports are marked on the casting ‘UP’ and ‘DN’.
When facing the power unit with the motor up, plug the right
hand, or ‘DN’ port. Jog the motor until oil flows from the left
hand, or ‘UP’ port. If oil does not flow from the ‘UP’ port, re-
verse the wire leads on the motor, and repeat. The pump is
now primed. Connect the hose (or tubing) to the ‘UP’ port and
tighten. Connect the other hose end to the blind end of a fully
retracted hydraulic cylinder. With the hose fitting loose, operate the power unit until oil (and
no air) bleeds from the fitting. Tighten the fitting. Refill the reservoir.
