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.
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.
IMPORTANT: Do not lift hydraulic
equipment by the hoses or swivel
couplers. Use the carrying handle or other
means of safe transport.

Summary

Important Receiving Instructions

Safety Issues and Warnings

Personal Protective Gear Warning

Wear appropriate protective gear when operating hydraulic equipment.

Load Support Warning

Stay clear of hydraulically supported loads; block loads mechanically after lifting/lowering.

Keep Clear During Operation Danger

Keep hands and feet away from cylinder and workpiece during operation.

Equipment Rating Warning

Do not exceed equipment ratings or connect to higher pressure pumps.

Relief Valve Setting Warning

Never set the relief valve higher than the pump's maximum rated pressure.

System Pressure Limit Warning

System operating pressure must not exceed the lowest rated component's pressure.

Safe Lifting and Transport

Do not lift hydraulic equipment by hoses; use carrying handle or safe transport means.

Operational Cautions and Dangers

Heat and Flame Caution

Keep hydraulic equipment away from flames and heat to prevent leaks and material weakening.

Pressurized Hose Danger

Do not handle pressurized hoses; escaping oil can penetrate skin causing serious injury.

Stable Setup Warning

Ensure setup is stable before lifting loads; use flat surfaces and cylinder bases.

Load Centering Warning

Avoid off-center loads on cylinder plungers to prevent strain, slipping, or falling.

Load Distribution and Saddle Use

Distribute load evenly and use a saddle to protect the plunger.

Qualified Service and Oil

Service hydraulic equipment only with genuine ENERPAC parts and qualified technicians.

Genuine Parts Warning

Replace worn/damaged parts with genuine ENERPAC parts to prevent failure and injury.
