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.
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.
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.
