SAFETY FIRST
2.0 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.
ACAUTION is used to indicate correct operating or
maintenance procedures and practices to prevent damage
to, or destruction of equipment or other property.
AWARNING indicates a potential danger that requires
correct procedures or practices to avoid personal injury.
ADANGER 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. Acylinder, 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 ONLYRIGID 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: Do not exceed equipment ratings. Never
attempt to lift a load weighing morethan
the capacity of the cylinder. Overloading causes
equipment failure and possible personal injury. The cylinders
are designed for a max. pressure of 700 bar [10,000 psi]. Do
not connect a jack or cylinder to a pump with a higher
pressure rating.
Never set the relief valve to a higher pressure than
the maximum rated pressure of the pump. Higher
settings may result in equipment damage and/or
personal injury.
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
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
of65°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 entiresaddle
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.
Disconnect air supply when pump is not in use.
NEVER remove swivel air connector while air line is
pressurized.
The pump is equipped with an overload valve, preset
for maximum operating pressure. DO NOT attempt to
adjust the overload valve. If adjustment is required,
contact an Enerpac Service Center.Adjustment by other than
qualified personnel may cause malfunction, damage to the
system, and/or personal injury.

overfill the reservoir will cause
the reservoir to become
pressurized. If the reservoir is subjected
to high pressure, the casing may
rupture, causing personal injuryand/or
equipment damage.
3. Replace the fill plug and finger
tighten.
CAUTION: DO NOT use a wrench. Over-tightening
will tear the reservoir bladder.
4. Tip the pump and check for leakage. If leakage occurs,
remove the plug and check the plug seal for cuts or
nicks. Replace the seal if necessary.
5. Replace the fill plug making sure the seal is centered
properly on the plug. If leakage still occurs, remove oil
and take pump to your nearest Enerpac Service Center.
