3.0 PRODUCT DATA
®
Do not drop heavy objects on hose. A
sharp impact may cause internal damage
to hose wire strands. Applying pressure to
a damaged hose may cause it to rupture.
IMPORTANT: Do not lift hydraulic
equipment by the hoses or swivel couplers.
Use the carrying handle or other means of
safe transport.
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. Protect hoses and cylinders from weld
spatter.
DANGER: 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: Only use hydraulic cylinders in
a coupled system. Never use a cylinder with
unconnected couplers. If the cylinder
becomes extremely overloaded, components can fail
catastrophically causing severe personal injury.
IMPORTANT: Hydraulic equipment must
only be serviced by a qualified hydraulic
technician. For repair service, contact the
Authorized ENERPAC Service Center in your area. To
protect your warranty, use only ENERPAC oil.
WARNING: Immediately replace worn or
damaged parts with genuine ENERPAC
parts. Standard grade parts will break
causing personal injury and property damage.
ENERPAC parts are designed to fit properly and
withstand high loads.
