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.
Distribute the load evenly across the entire saddle
surface. Always use a saddle to protect the plunger.
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 by 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.
