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 safety

precautions 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 the product

operating specifications. The cylinders

are designed for a maximum pressure of

70 bar [1000 psi]. Never adjust the circuit pressure

beyond the maximum operating pressure

recommendation for the clamp arm length.

Exceeding these specifications can cause equipment

failure and possible personal injury.

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.
