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.
