HYDRAULIC TOWER POWER UNIT
GENERAL START UP INSTRUCTIONS
NOTE: The ports are marked on the casing UP
and DN. When facing the power unit with the
motor up, plug the right hand, or DN port Jog
the motor until the 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 re-
peat. 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.
