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.
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. 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.
