Enerpac PMU10022 Manuel D'instructions page 2

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:
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
overloaded, components can fail catastrophically causing
severe personal injury.
WARNING: BE SURE SETUP IS STABLE BEFORE
LIFTING LOAD. Cylinders should be placed on a
flat surface that can support the load. Where
applicable, use a cylinder base for added stability. Do
not weld or otherwise modify the cylinder to attach a base or
other support.
Avoid situations where loads are not directly centered
on the cylinder plunger. Off-center loads produce
considerable strain on cylinders and plungers. In
addition, the load may slip or fall, causing potentially
dangerous results.
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.
WARNING: Do not use hoses, fittings, or couplers with
pressure ratings below 11,600 psi [800 bar].
Equipment with inadequate pressure rating can fail
extremely
and cause personal injury or equipment damage.
CAUTION: To avoid personal injury, do not use electric
pumps in an explosive atmosphere. Adhere to all local
and national electrical codes.
To prevent damage to pump's electric motor, check
specifications and motor plate data.
To help prevent pump failure, check hydraulic
reservoir fluid level prior to pump operation.
If fluid level is low, add oil. Always be sure tools are
fully retracted before adding fluid to the reservoir.
