CAUTION: Avoid damaging hydraulic hose. Avoid

sharp bends and kinks when routing hydraulic
hoses. Using a bent or kinked hose will cause severe

back-pressure. Sharp bends and kinks will internally damage
the hose leading to premature hose failure.

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: Keep hydraulic equipment away from

flames and heat. Excessive heat will soften
packings and seals, resulting in fluid 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: Do not handle 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

flat 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 qualified 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 and property

damage. ENERPAC parts are designed to fit properly and
withstand high loads.

WARNING: Do not use hoses, fittings, or couplers with
pressure ratings below 10,000 psi [700 bar].
Equipment with inadequate pressure rating can fail

and cause personal injury or equipment damage.

CAUTION: To avoid personal injury, do not use electric
pumps in an explosive atmosphere. Adhere to all local
and national electrical codes.

To prevent damage to pump's electric motor, check
specifications and motor plate data.

To help prevent pump failure, check hydraulic
reservoir fluid level prior to pump operation.

If fluid level is low, add oil. Always be sure tools are
fully retracted before adding fluid to the reservoir.

4.0 INSTALLATION

Check oil level in reservoir. Oil level should be 1 inch below
vent/fill plug opening. If necessary, add Enerpac hydraulic oil
to bring oil level up to 1 inch below the vent/fill opening.

NOTE: Use only Enerpac hydraulic oil. Use of any other oils
and fluids may damage pump or seals and will void the
warranty on your pump.
