SYSTEM
4.1 Working Pressure
The factory preset system pressure for 60 ton is 6,000 psi, 100
ton is 9,700 psi, 150 ton is 10,200 psi, and 200 ton is 10,200 psi.
4.2 Adding Oil
The unit is shipped with the correct amount of oil. Verify oil level
before by removing the OIL FILLER CAP and add ENERPAC
HF hydraulic oil into reservoir if necessary. Oil level should not
exceed 1" from the reservoir top plate cover.
Oil Filler Cap
WARNING: Loose or improperly threaded fittings can
be potentially dangerous if pressurized, however,
severe over tightening can cause premature thread
failure. Fittings need to be tightened secure and leak free. Never
hold or stand directly in line with any hydraulic connections while
pressurizing. Never grab, touch or in any way come in contact
with a hydraulic pressure leak. Escaping oil can penetrate the
skin and a serious injury can result.
4.3 How to Use The Handle Assembly
1. Push lever (callout #1) to release
locking pin.
2. Raise handle assembly (callout #2)
upward and pull handle assembly
(callout #1) to engage lock pin into
desired hole setting.
3. Pow’r-Riser can now be pushed or
pulled (be mindful walking backwards)
to work area.
4. If necessary, the Pow’r-Riser should
be picked up by the lifting bar, or by
the eyebolt for higher ton models
(callout #3).
Never attempt to pick
jack up by handle assembly.
4.4 Using the Jack For The First Time
1. Locate the valve control and make sure it’s in the neutral
or center position (note: solenoid valves are in the center
or neutral position when the button(s) are not depressed on
pendant).
2. Connect an Air Source to the AIR SUPPLY VALVE
(callout #4).
3. Open the AIR SUPPLY VALVE (callout #4) on the unit to turn
the motor “on”. Check for any leaks, repair as needed.
Shift the control valve to the advance and retract position and
look for movement in cylinder. Check for any leaks, repair as
needed. For solenoid operation, use pendant control to operate
cylinder movement.
