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 fl ames and heat. Excessive
heat will soften packings and seals,
resulting in fl uid leaks. Heat also
weakens hose materials and packings. For optimum
