1.0 IMPORTANT RECEIVING INSTRUCTIONS

Visually inspect all components for shipping damage. Shipping
damage is not covered by warranty. If shipping damage is found,
notify carrier at once. The carrier is responsible for all repair and
replacement costs resulting from damage in shipment.

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.

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: Do not exceed equipment ratings. Never
attempt to lift a load weighing more than 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 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.

Distribute the load evenly across the entire saddle
surface. Always use a saddle to protect the plunger.

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.

area. To protect your warranty, use only ENERPAC oil.

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

IMPORTANT: Hydraulic equipment must only be serviced
by a qualified hydraulic technician. For repair service,
contact the Authorized ENERPAC Service Center in your

WARNING: Immediately replace worn or damaged parts
by genuine ENERPAC parts. Standard grade parts will
break causing personal injury and property damage.
