Do not drop heavy objects on hose. A
sharp impact may cause internal damage
to hose wire strands. Applying pressure to
a damaged hose may cause it to rupture.
IMPORTANT: Do not lift hydraulic equipment
by the hoses or swivel couplers. Use the
carrying handle or other means of safe
transport.
CAUTION:
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:
PRESSURIZED 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, components can fail
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: Hydraulic equipment must
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.

withstand high loads.
3.0 INSTALLATION
1. Make hydraulic connections. For single-acting
cylinders (1) use a pump with a release valve (or
a 3-way valve) and one hose. For double-acting
cylinders (2) use a pump with a 4-way valve and
two hoses.
WARNING: On double-acting cylinders
be certain that hoses are connected at
BOTH couplers.
pressurize a double-acting cylinder if only
one hose is connected.
2. Fully hand-tighten all couplers. Loose coupler
connections will block the fl ow of oil between the
pump and the cylinder.
3. Remove air from the cylinder:
Single-acting cylinders: Position the cylinder so
that the plunger is pointed down and the cylinder
is lower than the pump. Fully extend and retract
the cylinder several times, until operation is
smooth.
Double-acting cylinders: Lay the cylinder on its
side so that the couplers are facing up. Fully
extend and retract the cylinder several times,
until operation is smooth.
4. Install adaptors and attachments as required.
NOTES:
• During adaptor installation, extend the plunger
and apply approximately 1500 to 2000 psi
[103 to 138 bar] of hydraulic pressure. This will
help keep the plunger from turning inside the
cylinder base.
