1.0 SAFETY
1.1 Important Safety Instructions
Read all instructions carefully. Follow all recommended safety
precautions to avoid personal injury as well as damage to the
pump and/or damage to other property. Enerpac cannot be
responsible for any damage or injury from unsafe use, lack of
maintenance or incorrect operation. Do not remove warning
labels, tags, or decals. In the event any questions or concerns
arise, contact Enerpac or a local Enerpac distributor for
clarification.
SAVE THIS INSTRUCTION SHEET FOR FUTURE USE
Appropriate training in the safe use of high pressure, high force
hydraulic tools is required prior to the operation of the pump.
If training is needed, contact your local Enerpac distributor or
authorized service center for information about an Enerpac
hydraulic safety training course.
This manual follows a system of safety alert symbols, signal
words and safety messages to warn the user of specific hazards.
Failure to comply with these warnings could result in death or
serious personal injury, as well as damage to the equipment or
other property.
The Safety Alert Symbol appears throughout this
manual. It is used to alert you to potential physical
injury hazards. Pay close attention to Safety Alert
Symbols and obey all safety messages that follow this symbol to
avoid the possibility of death or serious personal injury.
Safety Alert Symbols are used in conjunction with certain Signal
Words that call attention to safety messages or property damage
messages and designate a degree or level of hazard seriousness.
The Signal Words used in this manual are DANGER, WARNING,
CAUTION and NOTICE.
Indicates a hazardous situation that, if not
avoided, will result in death or serious personal
injury.
Indicates a hazardous situation that, if not
avoided, could result in death or serious
personal injury.
Indicates a hazardous situation that, if not
avoided, could result in minor or moderate
personal injury.
Indicates information considered important,
but not hazard related (e.g. messages relating
to property damage). Please note that the
Safety Alert Symbol will not be used with this
signal word.
1.2 General Hydraulic Safety Precautions
WARNING
Failure to observe and comply with the following precautions
could result in death or serious personal injury. Property
damage could also occur.
• Do not remove or disable the pressure relief valve.
• Never set the pressure relief valve to a higher pressure than
the maximum rated pressure of the pump.
• Stay clear of cylinders and tools while they are being
pressurized or in operation. To avoid personal injury, keep
hands and feet away from pinch point areas.
• Do not handle pressurized hydraulic hoses. Escaping oil under
pressure can penetrate the skin. If oil is injected under the
skin, see a doctor immediately.
• Do not pressurize disconnected couplers.
• Use only double-acting hydraulic cylinders or tools in a
coupled system. Never use a double-acting cylinder or tool
with uncoupled couplers. If the cylinder or tool becomes
extremely overloaded, components can fail catastrophically.
• Use only rigid pieces to hold loads. Carefully select steel or
wood blocks that are capable of supporting the load.
• Never use a hydraulic cylinder or tool as a shim or spacer in
any application.
• Avoid situations where loads are not directly centered on the
cylinder plunger. O-center loads produce considerable strain
on cylinders and plungers. In addition, the load may slip or fall.
• The system operating pressure must not exceed the pressure
rating of the lowest rated component in the system. Install
pressure gauge(s) in the system to monitor operating pressure.
It is your window to see what is happening in the system.
• 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.
• Wear personal protective equipment (P.P.E.) when operating
hydraulic equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
• Be sure setup is stable before lifting load. Cylinders should
be placed on a flat surface that can support the load. Where
applicable, use a cylinder base for added stability. Do not weld
or otherwise modify the cylinder to attach a base or other
support.
• Immediately replace worn or damaged parts with genuine
ENERPAC parts. Standard grade parts will break causing
personal injury and property damage.
CAUTION
Failure to observe and comply with the following precautions
could result in minor or moderate personal injury. Property
damage could also occur.
• Do not use or repair damaged hydraulic hoses. 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 hydraulic hoses. A sharp impact
may cause internal damage to hose wire strands. Applying
pressure to a damaged hose may cause it to rupture.
• Do not lift hydraulic equipment by the hoses or swivel couplers.
Use the carrying handle or strap.
• 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.
• Protect all hydraulic equipment from weld spatter.
• Immediately replace worn or damaged parts with genuine
Enerpac parts. Enerpac parts are designed to fit properly and
to withstand high loads. Non-Enerpac parts may break or
cause the pump to malfunction.
Hydraulic equipment must only be serviced by a
qualified hydraulic technician. For repair service, contact the
Enerpac Authorized Service Center in your area.
