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. Recommended 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, reverse 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.
