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.

ZW4-5 Pallet De-Coupling Pumps
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.
DANGER: 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. Do not remove relief valve.
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.
