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 pump lifting/transport

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 150° F
[65° C] 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 with 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.

CAUTION: Always use the pump lifting/
transport handle to carry the pump.
Carrying the pump by the hose may

damage the hose and/or the pump.
