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.

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.
