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.
®
WARNING: BE SURE SETUP
IS STABLE BEFORE LIFTING
LOAD.
Cylinders should be
p l a c e d o n 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 10,000 psi [700 bar]. Equipment
with inadequate pressure rating can fail 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.
4.0 INSTALLATION
1. Check oil level in reservoir. Oil level should be 1 inch below
vent/fill plug opening. If necessary, add Enerpac hydraulic oil
to bring oil level up to 1 inch below the vent/fill opening.
NOTE:
Use only Enerpac hydraulic oil. Use of any other
oils and fluids may damage pump or seals and will void the
warranty on your pump.
