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 350 bar [5,000 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.
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.
