• Do not expose the lifting wedge 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 lifting wedge with uncoupled couplers.
• Do not remove or disable the pump relief valve.
• Install pressure gauge(s) in the system to monitor operating
pressure. It is your window to see what is happening in the
system (LW-16 only).
CAUTION
Failure to observe and comply with the following
precautions could result in minor or moderate personal
injury. Property damage could also occur.
• To help ensure proper operation and best performance, use
only the Enerpac specified hydraulic oil for your Enerpac
product. 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 lifting eye (if equipped) or handle 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.
• To avoid personal injury keep hands and feet away from
lifting wedge, pressurized hose and load during operation.
NOTICE Ensure that any repairs are performed only by
trained, qualified and authorized personnel using original
equipment replacement parts. For repair service, contact the
Enerpac Authorized Service Center in your area.
