• Always be certain that hydraulic pressure is fully
relieved before disconnecting hydraulic hoses,
loosening hydraulic fittings, or performing any tool
disassembly or repair procedures.
CAUTION
Failure to observe and comply with the
following precautions and instructions could result
in minor or moderate personal injury. Property
damage could also occur.
• To help ensure proper operation and best
performance, use only Enerpac HF hydraulic oil. Use
of any other oil may result in unsafe operation and /or
damage to tool. The Enerpac product warranty may
also be invalidated.
• 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 back-pressure. Sharp bends
and kinks will internally damage the hose, leading to
premature hose failure.
• Do not drop heavy objects on 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 couplers.
Use the equipment handle(s) or lifting eye(s) (if equipped)
and appropriately rated lifting equipment.
• 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.
1.4 Safety Symbols (on cutter)
WARNING
Failure to observe and comply with the
safety symbols affixed to the cutter housing could
result in death or serious personal injury.
WARNING Make sure the safety symbols (decals,
labels, etc.) are securely affixed to the tool and that
they are legible. If not, obtain replacements from
Enerpac. Refer to tool repair parts sheet for locations
and part numbers. Failure to maintain safety symbols
on tool could result in death or serious personal
injury.
The following safety symbols are affixed to the cutter
housing:
Crush hazard: Keep hands, fingers and other
body parts away from the cutting head during
operation.
Projectile hazard: Objects may be ejected
from the cutter during operation. Stay clear of
cutting area. Wear eye and face protection.
PPE Alert: Wear personal
protective equipment
(PPE) when using or
servicing equipment.
1.3 General Hydraulic Tool Safety Precautions
(Tools with external hydraulic pumps)
NOTICE:
WARNING Failure to observe and comply with the
following precautions and instructions could result
in death or serious personal injury. Property damage
could also occur.
• Always read, follow and completely understand
all manufacturer's instructions when operating
pumps, valves and all other devices used with the
tool. Follow all safety precautions contained in the
manufacturer's manuals.
• Use the tool only with a compatible Enerpac pump.
Use of a non-compatible pump may result in erratic
and/or unsafe operation.
• The tool is designed for a maximum working pressure
of 10,150 psi [700 bar]. Do not connect the tool to a
pump with a higher pressure rating. Be certain that all
hydraulic hoses and fittings are properly connected
and that they are rated at 10,150 psi [700 bar] or
higher.
• Never set a relief valve to a higher pressure than
the maximum rated pressure of the pump and tool.
If ratings are different, relief valve setting should not
exceed the setting of the lowest rated component
(pump or tool).
• Perform cleaning, maintenance and repair operations
only after disconnecting the tool from the hydraulic
pump.
• Wear suitable personal protective equipment (PPE)
such as goggles, gloves and protective clothing
when checking hoses and fittings.
• Do not leave the tool unattended in the workplace
when it is connected to the hydraulic pump.
• The tool is designed for noncontinuous use. Allow
sufficiently long pauses to allow the oil to cool.
Consult Enerpac if prolonged and/or interrupted use
is required.
• Do not expose tool to temperatures in excess of
158°F [70°C]. Allow tool to cool or remove heat
source.
• Be aware of hot metal components. Avoid contact
with these components to prevent burns.
• Do not handle pressurized 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.
• Never use a hydraulic cylinder or tool with uncoupled
couplers.
• Do not remove or disable the pump relief valve.
Do not remove or disable the tool relief valve (if
equipped).
• Monitor the system hydraulic pressure gauge (or
digital pressure readout). It is your window to see
what is happening in the system.
