1. Safety 1.1 Safety Precautions

Failure to observe and comply with the following

precautions could result in death or serious personal

injury. Property damage could also occur.

• Read and completely understand the safety

precautions and instructions in this manual before

operating the pump or preparing it for use. Always

follow all safety precautions and instructions,

including those that are contained within the

procedures of this manual.

• Operating procedures will vary, depending on

the system arrangement. Always read, follow,

and completely understand all manufacturer’s

instructions when operating the powerpack and

all other devices used with it. Follow all safety

precautions contained in the manufacturer’s

manuals.

• Always wear appropriate personal protective

equipment (P.P.E.) when operating hydraulic

equipment. Be sure to wear eye protection, work

gloves and protective clothing. Use of additional

P.P.E. safety items such as dust mask, non-skid

safety shoes, hard hat, and hearing protection

(used as appropriate for the conditions) will reduce

the chance of personal injuries. The use of these

items may also be required by local regulations or

laws.

• Do not handle pressurized hoses. Escaping oil

under pressure can penetrate the skin. If oil is

injected under the skin, see a doctor immediately.

• Do not pressurize disconnected couplers.

• Use hydraulic cylinders only in a coupled system.

Never use a cylinder with uncoupled couplers.

If the cylinder becomes extremely overloaded,

components can fail catastrophically causing

severe personal injury.

• Do not remove or disable the pump relief valve.

• Install pressure gauge(s) in the system to monitor

operating pressure. It is your window to see what

is happening in the system.

• Never set a relief valve to a higher pressure than

the maximum rated pressure of the pump and

cylinder. If ratings are different, relief valve setting

should not exceed the setting of the lowest rated

component (pump or cylinder). Higher settings

may result in equipment damage and/or personal

injury.

• Do not exceed equipment ratings. Never attempt

to lift a load weighing more than the rated capacity

of the cylinder. Overloading may cause equipment

failure and possible personal injury.

• Be sure setup is stable before moving load.

• Always perform a visual inspection of the equipment

before placing it into operation. If any problems are

found, do not use it. Have the equipment repaired

and tested by an Enerpac Authorized Service

Center before it is returned to service.

• Allow only trained and experienced personnel to

supervise and perform procedures.

• Use only rigid pieces to hold loads. Carefully select

steel or wood blocks that are capable of supporting

the load.

Read all instructions carefully. Follow all recommended

safety precautions to avoid personal injury as well

as damage to the product and / or damage to other

property. Enerpac cannot be responsible for any

damage or injury from unsafe use, lack of maintenance,

or incorrect operation. Do not remove warning labels,

tags, or decals. In the event that any questions or

concerns arise, contact Enerpac or a local Enerpac

distributor for clarification.

Save these instructions for future use.

If you have never been trained on high-pressure

hydraulic safety, consult your distributor or service

center for information about Enerpac Hydraulic Safety

Courses.

This manual follows a system of safety alert symbols,

signals, words, and safety messages to warn the user of

specific hazards. Failure to comply with these warnings

could result in death or serious personal injury, as well

as damage to the equipment or other property.

The Safety Alert Symbol appears throughout

this manual. It is used to alert you to potential

physical injury hazards. Pay close attention

NOTICE

4L4739_a

• Move only dead weight loads, avoid live weight

loads.

• Be especially careful when moving loads such as

partially filled storage tanks, in which the center

of gravity could move or shift during procedure.

Be aware that the distribution of some loads can

change quickly and without warning.

• Maintain communication with the operator at all

times during procedure to avoid accidents. Use

hand signals, two- way radios or other appropriate

forms of communication (as required by applicable

laws and regulations) if the load is not visible to the

operator.

• Operate pump and valve as required to ensure that

the load is moved evenly and at a controlled rate.

• Closely watch the load at all times during operation.

Stop work immediately if the load becomes

unstable or appears to be moving unevenly.

• Stay clear of loads supported only by hydraulics.

As required, follow the moved load with cribbing.

• Never allow persons to work under or near the load

while the load is being supported hydraulically.

• Always be certain that hydraulic pressure is fully

relieved and that the load is fully removed from the

cylinder(s) before disconnecting hydraulic hoses,

loosening hydraulic fittings, or performing any

cylinder disassembly or repair procedures.

• Do not use electric pumps in an explosive

atmosphere. Adhere to all local and national

electrical codes. A qualified electrician must do

installation and modification.

• Start the pump with the valve in the neutral position

to prevent accidental cylinder operation.

• These pumps have internal factory adjusted relief

valves, which must not be repaired or adjusted

except by an Authorized Enerpac Service Center.

• To prevent damage to pump electric motor, check

specifications. Use of incorrect power source will

damage the motor.

Failure to observe and comply with the following

precautions could result in minor or moderate

personal injury. Property damage could also occur.

• Be careful to avoid damaging hydraulic hoses.

Avoid sharp bends and kinks when routing hydraulic

hoses. Do not exceed the minimum bend radius

specified by the hose manufacturer. 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 hoses. A sharp

impact may cause internal damage to hose wire

strands. Applying pressure to a damaged hose

may cause it to rupture.

• Do not lift hydraulic equipment by the hoses

or couplers. Use the cylinder lifting eyes and

appropriately rated lifting equipment.

• 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.

CAUTION

• For optimum performance, do not expose hydraulic

equipment to temperatures of 150˚F [65˚C] or

higher. Protect all hydraulic equipment from weld

spatter.

• To prevent damage to pump electric motor, check

specifications. Use of incorrect power source will

damage the motor.

• Immediately replace worn or damaged parts with

genuine Enerpac parts. Enerpac parts are designed

to fit properly and to withstand high loads. Non-

Enerpac parts may break or cause the product to

malfunction.

• Hydraulic equipment must only be serviced by a

qualified hydraulic technician. For repair service,

contact the Enerpac Authorized Service Center in

your area.

• To help ensure proper operation and best

performance, use of Enerpac oil is strongly

recommended.

5.2 Hydraulic Oil Requirements

Use of Enerpac HF Series ISO 32 hydraulic oil is

recommended. Enerpac HF oil is available at your local

Enerpac Distributor or Authorized Service Center.

• Failure to use the correct oil type (high-quality ISO

32 hydraulic oil) may result in damage to cylinder

hydraulic components and will void the product

warranty.

• Be sure that the oil is clean. The oil cleanliness

should be maintained to a maximum level of

18/16/13 per the ISO4406 standard. If the oil

develops a milky, cloudy, or dark appearance, it

should be changed immediately.

• To avoid overfilling and possible equipment

damage, add oil to the pump reservoir only after

all cylinder plungers are completely retracted and

system pressure is released.

5.3 Hydraulic Connections

Be certain that all couplers are fully connected, so that

hydraulic flow is not blocked. All hoses, fittings and

other hydraulic components in the circuit must be rated
