INSTALLATION
Adding Fluid
a
WARNING
Before adding fluid, make sure the plunger is fully retracted, or the
system will contain more fluid than the reservoir can hold.
1. Use wrench end of jack handle to open release valve by turning counter-clockwise.
2. Place jack on its side with fill plug facing up. Remove fill plug.
3. Slowly add Enerpac hydraulic fluid. Do not fill reservoir completely. Fluid level
should be below fill plug when jack is upright.
4. Stand jack upright, allowing excess fluid to run out of fill plug hole. Replace fill plug.
Clean off excess fluid.
Removing Air
1. On 30 - 100 Ton models, open air vent.
2. Use wrench end of jack handle to open release valve by turning counter-clockwise.
3. Insert jack handle into jack pump beam and rapidly pump the handle.
4. Use wrench end of jack handle to close release valve by turning clockwise.
5. If jack operation is not smooth, repeat the air removal procedure.
