SAFETY FIRST
2.0 SAFETY ISSUES
Make sure to read the instructions, warnings and
precautions carefully. Follow any recommended
safety precautions to avoid personal injury or
damage to the unit. 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 Distributor for clarification.
The hydraulic system’s maximum working pressure is 10,000 PSI
(700kg/cm2).
If you have never been trained on high-pressure hydraulic safety,
consult your distributor 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: This jack is for lifting only!! Support the load
after completing the lift by other appropriate means.
Never get under a load supported by the jack.
Never exceed the rated capacity of the jack. Allow at least ten
percent margin of safety.
DANGER: To avoid personal injury, keep hands
and feet away from hydraulic unit and work-
piece during operation. 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.
WARNING: Never set the relief valve to a higher pressure
than the maximum rated pressure. Higher settings may
result in equipment damage and/or personal injury.
CAUTION: Fully retract the cylinder and protect the
entire unit from external damage. Keep Pow’r-Risers
clean, avoid weld splatter, and store in a clean dry area.
INSPECT ALL SYSTEM COMPONENTS BEFORE USE.
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.
WARNING: BE SURE SETUP IS STABLE BEFORE
LIFTING LOAD. Use jack only on solid surface
compatible of supporting the load and base of the
jack. Always center the load on the lifting saddle of the jack. If the
jack is not perpendicular to the load slipping or loss of load is
possible.
Distribute the load evenly when performing multiple lifts.
Use only ENERPAC HF hydraulic oil, or approved
equivalent. Failure to heed these warnings may cause
loss of load or failure of the jack resulting in property
damage or personal injury.
WARNING: The internal relief valve must not be repaired
adjusted except by an authorized service center.
