IMPORTANT:
equipment by the hoses or swivel couplers.
Use the carrying handle or other means of
safe transport.
CAUTION: Keep hydraulic equipment
away from fl ames and heat. Excessive
heat will soften packings and seals,
resulting in fl uid leaks. Heat also
weakens hose materials and packings. For optimum
performance do not expose equipment to temperatures
of 65°C [150°F] or higher. Protect hoses and cylinders
from weld spatter.
DANGER
hoses. Escaping oil under pressure can
penetrate the skin, causing serious injury.
If oil is injected under the skin, see a doctor
immediately.
WARNING
: Only use hydraulic cylinders in a
coupled system. Never use a cylinder with
unconnected couplers. If the cylinder becomes
extremely overloaded,
catastrophically causing severe personal injury.
WARNING: BE SURE SETUP IS
STABLE BEFORE LIFTING LOAD.
Cylinders should be placed on a fl at surface
that can support the load. Where applicable, use a
cylinder base for added stability. Do not weld or
otherwise modify the cylinder to attach a base or
other support.
Avoid
situations where loads are not
directly centered on the cylinder plunger.
Off-center loads produce considerable
strain on cylinders and plungers. In addition, the load
may slip or fall, causing potentially dangerous results.
Distribute the load evenly across the entire
saddle surface. Always use a saddle to
protect the plunger.
IMPORTANT
only be serviced by a qualifi ed hydraulic
technician. For repair service, contact the
Authorized ENERPAC Service Center in your
area. To protect your warranty, use only ENERPAC oil.
WARNING
: Immediately replace worn or
damaged parts by genuine ENERPAC parts.
Standard grade parts will break causing
personal injury
ENERPAC parts are designed to fi t properly and
withstand high loads.
3.0 INSTALLATION
1. Make hydraulic connections. Use a pump with a
release valve or a 3-way valve and one hose for
single-acting spring return Lifting Wedges.
IMPORTANT: Fully hand-tighten all couplers.
Loose coupler connections will block the fl ow of
oil between the pump and the Lifting Wedge.
Do not lift hydraulic
: Do not handle pressurized
components can
: Hydraulic equipment must
and property damage.
2. Remove air from the drive cylinder by holding
the Lifting Wedge by the handle, lift jaws
pointed downward and the drive cylinder is
lower than the pump. Fully extend and retract
the Lifting Wedge 2 or 3 times by pumping the
pump handle.
NOTE: The pump cap should be loosened to
provide an air vent through the system as the
Lifting Wedge is advanced. Failure to vent the
system will result in a vacuum and the Lifting
Wedge will not advance.

4.0 OPERATION
Operate the hydraulic pump to advance and retract
the Lifting Wedge. The Lifting Wedge drive cylinder is
single-acting, spring-return. The speed of retraction
is affected by the length of the hose and other
restrictions in the line.
WARNING: Never place fi ngers or hands
under a load being lifted.
WARNING: Lifting Wedge and/or Safety
Block must be fully inserted under load
until the heel of the lifting step resides
against the side of the load.
