1. Safety
1.1 Safety Precautions
Failure to observe and comply with the following
precautions could result in death or serious personal
injury. Property damage could also occur.
• Always wear protective head-wear, ear protectors,
footwear and gloves (at a minimum rigger type
gloves) suitable for safe operation of the tool.
The protective clothing must not interfere with
safe operation of the tool or restrict the ability to
communicate with co-workers.
• Be sure your workplace is safe. Follow the
instructions in your workplace’s standard
operating procedures and be sure to observe all
communicated safety precautions.
• V17 check valves are designed for a maximum
working pressure of 10,150 psi [700 bar]. Do not
exceed equipment ratings.
• The system operating pressure must not exceed
the pressure rating of the lowest rated component
in the system
• Make sure that all system components are
protected from external sources of damage, such
as excessive heat, flame, moving machine parts,
sharp edges, and corrosive chemicals.
• Always be sure that pump is stopped and all pressure
is fully relieved (0 psi/bar) before disconnecting
or connecting hydraulic hoses. The sudden and
uncontrolled release of pressurized oil could occur
if hoses are disconnected while under pressure.
• Never attempt to connect or disconnect hoses while
the pump is on and/or the system is pressurized.
• Be certain that all hose couplings are fully
connected at both the pump and cylinder couplers
before applying any hydraulic pressure. If the
couplings are not fully connected, oil flow will be
blocked, and the cylinder could be subjected to
excessive hydraulic pressures. Catastrophic failure
of cylinder could result.
• Always perform a visual inspection of the equipment
before placing it into operation. If any problems are
found, do not use it. Have the equipment repaired
and tested by an Enerpac Authorized Service
Center before it is returned to service.
• Never use a tool that is leaking oil. Do not use a
tool that is damaged, altered or in need of repair.
• Be sure the operator has completed safety induction
training, specific to the work surroundings. The
operator should be thoroughly familiar with the
controls and the proper use of the tool.
• The operator must be of at least the minimum age
required by applicable local regulations, laws and
the facility standard operating procedures.
• Take every precaution to prevent oil leaks from
occurring. High pressure oil leaks can penetrate
the skin, resulting in serious injury.
• Never strike the tool while it is pressurized or under
WARNING
Read all instructions carefully. Follow all recommended
safety precautions to avoid personal injury as well
as damage to the product 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 that any questions or
concerns arise, contact Enerpac or a local Enerpac
distributor for clarification.
Save these instructions for future use.
If you have never been trained on high-pressure
hydraulic safety, consult your distributor or service
center for information about Enerpac Hydraulic Safety
Courses.
This manual follows a system of safety alert symbols,
signals, 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 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 related
to property damage). Please note that the Safety Alert
Symbol will not be used with the signal word.

load. Components under tension may become
dislodged, allowing them to become dangerous
projectiles. Uncontrolled release of pressurized
hydraulic oil could also occur.
• Avoid striking the tool at any time, even when it is
not pressurized or under load. Striking the tool could
cause permanent damage to cylinder components
and may affect the cylinder calibration.
Failure to observe and comply with the following
precautions could result in minor or moderate
personal injury. Property damage could also occur.
• Be careful to avoid damaging hydraulic hoses.
Avoid sharp bends and kinks when routing hydraulic
hoses. Do not exceed the minimum bend radius
specified by the hose manufacturer. Using a bent
or kinked hose will cause severe backpressure.
Sharp bends and kinks will internally damage the
hose, leading to premature hose failure.
• 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 hydraulic
equipment to temperatures of 150˚F [65˚C] or
higher. 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 product to
malfunction.
Failure to observe and comply with the following
precautions could result in property damage and/or
void the product warranty.
• Always use Enerpac pumps and hoses.
• Hydraulic equipment must only be serviced by a
qualified hydraulic technician. For repair service,
contact the Enerpac Authorized Service Center in
your area.
• To help ensure proper operation and best
performance, use of Enerpac oil is strongly
recommended.
