SAFETY FIRST

2.0  GENERAL HYDRAULIC SAFETY PRECAUTIONS

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.

CAUTION

 is used to indicate correct operating or 

maintenance procedures and practices to prevent damage to, 
or destruction of equipment or other property.

WARNING

 indicates a potential danger that requires correct 

procedures or practices to avoid personal injury.

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:

 Do not exceed equipment ratings. 

Overloading causes equipment failure and possible 
personal injury. The nut splitter is designed for a 

maximum pressure of 700 bar [10,000 psi]. Do not connect the 
nut splitter 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 
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.

IMPORTANT:

 Hydraulic equipment must only be 

serviced by a qualifi ed hydraulic technician. For repair 
service, contact the Authorized ENERPAC Service 

Center in your area. To protect your warranty, use only ENERPAC 
oil.

WARNING:

 Immediately replace worn or damaged 

parts with genuine ENERPAC parts. Standard grade 
parts will break causing personal injury and property 

damage. ENERPAC parts are designed to fi t properly and 
withstand high loads.
