1.0 SAFETY & GENERAL INFORMATION

Read all instructions, warnings and
cautions carefully. Follow all safety
precautions to avoid personal injury or

property damage during s ystem operation.
Enerpac cannot be responsible for damage or injury
resulting from uns afe product us e, lack of m aintenance
or incorrect product and/or system operation. Contact
Enerpac when in doubt as to the safety precautions
and operations. If you have never been trained on
high-pressure h ydraulic safet y, consult your dist ributio n
or service center for a free Enerpac Hydraulic safety
course.

Failure to comply with the following cautions and
warnings could cause equi pment damage and personal
injury.

A CAUTION is used to indicate correct operating or
maintenance procedures and practices to prevent
damage to, or destruction of equipment or other
property.

A WARNING ind icates a potential danger that requires
correct procedures or practices to avoid personal

2.0 SAFETY PRECAUTIONS

WARNING: Stay clear of loads suppor ted by

hydraulics. A cylinder, wh en used as a load
lifting device, should ne ver be us e d as a loa d

holding device. After the load has been
raised or lowered, it must always be blocked
mechanically.

WARNING: use only rigid pieces to hold

loads. Carefully select steel or wood blocks

that are capable of supporting the load.
Never use a hydraul ic cylinder as a shim or spac er in
any lifting or pressing application.

WARNING: Wear proper personal protective

gear when operating hydraulic equ ipm ent .

DANGER: To avoid personal injury keep
hands and feet away from cylinder and
workpiece during operation.

WARNING: Do not exceed equipment
ratings. Never att empt to lift a lo ad weighing

more than the capacity of the cylinder.
Overloading causes equipment failure and possible
personal injury.

A DANGER is only used when your action or lack of
action may cause serious injury or even death.

CAUTION: Do not connect a jack or cylinder

to a pump with a higher pressure rating.

Never set the relief valve to a higher

pressure than the maximum rated pressure

of the pump. Higher settings may result in
equipment damage and/or personal injury.

WARNING: The system operatin g pressure
must not exceed the pressure rating of the

lowest rated component in the system.
Install pressure gauges in the system to monitor
operating pressure. It is your window to what is
happening in the system.

CAUTION: Avoid damaging hydraulic hose.
Avoid sharp bends and kinks when routing
hydraulic hoses. Us ing a bent or kinked hose
will cause severe backpressure. Sharp
bends and kinks will internally damage the
hose leading to premature hose failure.

CAUTION: Do not drop heavy objects on
hose. A sharp impact may cause internal
damage to hose wire strands. Applying
pressure to a damaged hos e 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 optim um performance do
not expose equipment to temperatures of
65°C [150°F] or higher. Protect hoses and
cylinders from weld spatter.

DANGER: Do not hand le pres surized h oses.
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 hydra ulic cylinders in a
coupled system. Never use a cylinder with
unconnected couplers. If the cylinder
becomes extrem ely overloaded, com ponents
can fail catastrophically causing severe
personal injury.

WARNING: be sure setup is stable before
lifting load. Cylin ders 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 otherw ise modif y the
cylinder to attach a base or other support.

CAUTION: Avo id situations where loads ar e
not directly center ed on the c ylinder plunger.
Off-center loads produce considerab le strain
on cylinders and plungers. In addition, the
load may slip or fall, causing potentially
dangerous results.

CAUTION: D istribute 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.

WARNING: In case of leakage contact
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 electric pum ps in an
explosive atmosphere. Adhere to all local
and national electrical codes. A qualified
electrician must do installation and
modification

WARNING: Start the pump with the valve in
the neutral position to prevent accidental
cylinder operation. Keep hands clear of
moving parts and pressurized hoses.

WARNING: These pumps have internal
factory adjusted rel ief valv es , which m ust not
be repaired or adjusted except by an
Authorized Enerpac Service Center.

CAUTION: To prevent damage to pump
electric motor, check specifications. Use of
incorrect power source will damage the
motor.

CAUTION: Check motor rotation dir ection to
prevent damage to hydraulic pump (See 4.0
installation)
