General Safety

Never set the relief valve to a higher pressure than the maximum
rated pressure of the pump. Higher settings may result in equipment
damage or personal injury. Do not remove relief valve.

To avoid personal injury keep hands and feet away from cylinder and
work piece during operation.

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.

Do not pressurize disconnected couplers.

General Safety

Failure to comply with DANGER, WARNING or CAUTION statements
could cause equipment damage and personal injury.

Immediately replace worn or damaged parts with genuine ENERPAC
parts. Non genuine ENERPAC parts may break, causing personal injury
and property damage. ENERPAC parts are designed to fit properly and
withstand high loads.

Stay clear of loads supported by hydraulics.
A cylinder, when used as a load lifting device, should never be used as
a load holding device. After the load has been raised or lowered,
it must always be blocked mechanically.

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.

Use only rigid pieces to hold loads.
Carefully select steel or wood blocks that are capable of supporting the
load. Never use a hydraulic cylinder as a shim or spacer in any lifting or
pressing application.

Avoid situations where loads are not directly centered on the cylinder
plunger. O-center loads produce considerable strain on cylinders and
plungers. In addition, the load may slip or fall, causing potential danger.

The system operating pressure must not exceed the pressure rating of
the lowest rated component in the system. Install pressure gauge in the
system to monitor operating pressure. It is your window to see what is
happening in the system.

Do not exceed equipment ratings. Never attempt to lift a load weighing
more than the capacity of the cylinder. Overloading causes equipment
failure and possible personal injury. The cylinders are designed for a
max. pressure of 700 bar/10,000 psi/70 MPa. Do not connect a jack or
cylinder to a pump with a higher pressure rating.

Wear proper personal protective gear when operating hydraulic
equipment.

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 plate for added stability.
Do not weld or otherwise modify the cylinder to attach a base or other
support.

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.

Distribute the load evenly across the entire saddle surface.
Always use a saddle to protect the plunger.

Do not lift hydraulic equipment by the hoses or swivel couplers.
Use the carrying handle.

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 all hydraulic equipment from weld spatter.

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.

Do not exceed 25 percent duty cycle. Allow sucient time for the
pump to cool between operations.

Indicates a potential danger that requires correct procedures or
practices to avoid possible serious personal injury or death.

Is used to indicate correct operating or maintenance procedures
and practices to prevent minor or moderate injury or damage to /
destruction of equipment or other property.

WARNING CAUTION

Electrical Safety

Failure to comply with DANGER, WARNING or CAUTION statements
could cause equipment damage and personal injury.

Do not operate the pump in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. The pump creates sparks which may ignite the dust of fumes.

Do not expose the pump to rain or wet conditions. Water entering the pump will increase the risk of shock.

To avoid accidental starting, when carrying or moving the pump ensure the safety switch is in the locked position, and do not carry with hand or fingers on the trigger.

Do not operate pump if safety switch does not function. Seek repair assistance from an ENERPAC service center.

Remove battery pack from the pump before making any adjustments, performing maintenance or storing the pump.

Ensure the switch is in the locked position prior to inserting the battery pack.

Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create risk of fire when used with another battery pack.

Use the ENERPAC XC-Series pump only with MILWAUKEE ELECTRIC TOOL M28TM or V28TM Li-Ion battery packs. Use of any other battery packs may create risk of injury or fire.

When battery pack is not in use, keep it away from other metal objects like paperclips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to
another. Shorting the battery terminals together may cause burns or fire.

Under abusive conditions, liquid may be ejected from the battery. Avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected
from the battery can cause irritation or burns.

Read and understand the safety and operation instructions provided separately with the MILWAUKEE ELECTRIC TOOL battery and charger.
