DANGER: To avoid personal
injury keep hands and feet
away from cylinder and
workpiece during operation.
WARNING: Stay clear of loads
supported by hydraulics. After the load
has been raised or lowered, it must always
be blocked mechanically.
WARNING: Never pressurize
uncoupled couplers. Only use hydraulic
equipment in a coupled system.
CAUTION: Avoid sharp bends and kinks
in the hose which may cause damage.
Also, bends and kinks lead to premature
hose failure.
4.0 OPERATION
IMPORTANT: It is mandatory that the
operator has a full understanding of all
instructions, safety regulations, cautions
and warnings, before starting to operate
any of this high force tool equipment. In case of
doubt, contact Enerpac.
4.1 Before lifting a load
The cylinder must be
securely attached in the
toe lift base. Keep the
contact surface between
the toe lift and the load
clean. The contact surface
must be free of oil and
grease to avoid the load
slipping off.
Before lifting a load make
sure that the contact
surface of the toe lift
completely support the
load to avoid bending of
the toe.
The chains with the lock pins must always be
positioned in the support feet before lifting to avoid
the support feet from accidentally be moved during
lifting.
4.2 Advancing and retracting the jack
For complete operating instructions refer to the
instruction sheet included with each pump.
Handpumps
On handpumps with release valves, close relief valve
and raise and lower the pump handle to advance the
jack. To retract the jack, open the release valve.
On handpumps with two position valves, shift valve to
advance position and raise and lower the pump
handle to advance. To retract, shift the valve to the
retract position.
IMPORTANT: Open the pump relief valve slowly in
order to lower the load slowly.
Power pumps
Shift the valve on the pump to the advance position
and run the pump to advance the jack. To retract the
jack, shift the valve to the retract position.
4.3 Air removal
Advance and retract the jack several times avoiding
pressure build-up. Air removal is complete when the
jack motion is smooth.
