HYDRAULIC SYSTEM
1. Remove the
RED Plug in the pump assembly and replace with the
supplied BLACK plug. This is the reservoir venting system
and damage or inoperability may result if not changed out.
2. Attach the hydraulic hose to the pump. Be sure to use a quality
thread sealer on both connections
3. Attach an air line fitting for your shop air to other end of the pump.
4. Push the pump foot pedal to the release position (TOE END) to
relieve all internal pressure.
5. Push the MALE hose end, from the pump, into the FEMALE
Cylinder fitting.
6. Thread the retainer collar hand tight. NOTE: This procedure will insure that the male & female fittings
positively seat against each other, eliminating any possibility of air locking. CAUTION Failing to follow
this procedure may cause the cylinder to not retract and / or leak.
BLEED THE CYLINDER
