1.0 SAFETY ISSUES
Read all instructions, warnings and cautions
carefully. Follow all safety precautions to avoid
personal injury or property damage during system
operation. Enerpac cannot be responsible for damage or injury
resulting from unsafe product use, lack of maintenance or
incorrect product and/or system operation. Contact Enerpac
when in doubt as to the safety precautions and operations. If you
have never been trained on high-pressure hydraulic safety,
consult your distribution or service center for a free Enerpac
Hydraulic safety course.
Failure to comply with the following cautions and warnings could
cause equipment damage and personal injury.
A CAUTION is used to indicate correct operating or maintenance
procedures and practices to prevent damage to, or destruction
of equipment or other property.
A WARNING indicates a potential danger that requires correct
procedures or practices to avoid personal injury.
A DANGER is only used when your action or lack of action may
cause serious injury or even death.
WARNING: Wear proper personal protective gear when
operating hydraulic equipment.
WARNING: Stay clear of loads supported by
hydraulics. A cylinder, when used as a load lifting device,
should never be used as a load holding device. After the
load has been raised or lowered, it must always be blocked
mechanically.
WARNING: USE ONLY RIGID PIECES TO HOLD
LOADS. Carefully select steel or wood blocks that are
capable of supporting the load. Never use a hydraulic
cylinder as a shim or spacer in any lifting or pressing application.
DANGER: To avoid personal injury keep hands
and feet away from cylinder and workpiece
during operation.
WARNING: The system operating pressure must not
exceed the pressure rating of the lowest rated component
in the system. Install pressure gauges in the system to
monitor operating pressure. It is your window to what is happening
in the system.
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
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: 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 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.
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.
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 fi t properly and withstand high
loads.
WARNING: Do not use electric pumps in an explosive
atmosphere. Adhere to all local and national electrical
codes. A qualifi ed electrician must do installation and
modifi cation.
