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.
