CAUTION: Avoid damaging
hydraulic hose. Avoid sharp bends
and kinks when routing hydraulic
hoses. 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 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 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.
Do not remove the protective cover
during operation. Personal injury
can occur if hands are pinched
between cyllinder body and
clamping jaw.
