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 10,000 psi (700 bar). 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 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.
