IMPORTANT RECEIVING INSTRUCTIONS: Visually inspect all components for shipping damage. Shipping damage is not covered

by warranty. If shipping damage is found, notify carrier at once. The carrier is responsible for all repair and replacement costs resulting
from damage in shipment.

SAFETY FIRST

Carefully plan your system by selecting components designed to perform the intended operation and which will
adequately perform with existing equipment. Always check the product limitations regarding pressure ranges, load

capacities and set-up requirements. The system operating pressure must not exceed the pressure rating of the lowest
rated component in the system. Read all CAUTIONS, WARNINGS, and INSTRUCTIONS included with, or attached to, each product.
Follow all safety precautions to avoid personal injury or property damage during the system operation. ENERPAC CANNOT BE
RESPONSIBLE FOR DAMAGE OR INJURY RESULTING FROM UNSAFE USE OF PRODUCT, LACK OF MAINTENANCE, OR
INCORRECT PRODUCT AND SYSTEM APPLICATION. Contact Enerpac when in doubt as to safety precautions or applications.

DESCRIPTION

Enerpac cutters can be used for a variety of cutting operations.
The table below lists the size and type of material your tool is
capable of cutting.

Self-contained hydraulic cutters (WMC models) are extremely
portable. Hydraulic cutterheads (WHC & WHR models)
require 10,000 psi hydraulic pumps and are recommended for
applications where many cuts must be made in a short amount
of time.

OPERATION

PRELIMINARY INFORMATION: Be sure to observe safe operating procedures. Follow the warnings listed below and all
other safety information contained in this document or decals attached to cutter. Failure to do so will result in personal injury
and/or equipment damage.

WARNING

CUTTING HAZARD: Keep
hands away from cutter
blades. Only one person
should operate cutter. Do
not have one person working

WARNING

Never use the cutter on
electrically active or "hot" wire
or cable. Be sure power has
been turned o before working

on electrical wire or cable.
near the blades while another
person controls the pump.

1. WHC and WHR models: Couple pump hose to cutter. Turn
collar on coupler fi nger tight only. No tools are needed to make
this connection.

2. Select material to be cut. When cutting short pieces of wire
rope, clamp or tape it fi rst to help prevent wires from jamming
between the blade and head.

3. Inspect blade and cutting head. Cutting case hardened steel
will dent blades and cutting heads. The blades will eventually
fatigue and crack. Replace cracked blades immediately. DO
NOT operate tool with cracked or chipped blades.

4. Unlatch cutter head.

5. Place material between blade and head shear.

6. IMPORTANT: Securely latch the cutter head.

WARNING

When working with wire rope or
cable, wrap section being cut to
prevent pieces from fl ying loose
as they are cut.

Blade

9. If the material being cut (usually wire rope or soft cables)
seems to be cut but does not break free of the tool, the blade
is hung up on something and needs to be removed. See
"Troubleshooting" on page 3.

10. Lift release lever or shift pump to release position to retract
blade. If blade does not retract, see "Troubleshooting" on
page 3.

Lever

CAUTION

Most broken blades are the result of not latching the cutter
head. When the blade is advanced, it pushes on the cutter
head. As the cutter head is pushed open, a diagonal force
causes the blade to break, and, in some cases, the cutter
head may crack.

7. On self-contained units, push release lever in toward cutter
body. For hydraulic cutterheads, close or shift valve on pump to
advance position.

8. Operate handle or pump until blade is fully advanced. DO
NOT exceed maximum cutting limits printed on tool decal.

11. Return tool to carrying case to protect from dirt and
corrosion. Always keep a spare blade on hand.

NOTE: Do not operate an empty cutter. The new blade
and cutter head shear edges will "roll" slightly with the
fi rst material cut, creating a burr. This burr falls o as
the cut takes place. Extending the blade prior to the
fi rst material cut will also raise a burr on the blade. With
no material present to knock the burr o , the blade and
head shear edges may lock together and the cutter will
not retract. To correct this situation, the blade must be
removed. Remove blade screw and blade. Unlatch cutter
head.

Use a sharpening stone to remove burr from blade. Run
the stone across the blade on the fl at side (not the knife
edge side). Keep the stone fl at and parallel to the blade.
Take care not to create a gap between the blade and
head shear.

TROUBLESHOOTING

Problem

Blade will not advance.

Blade will not retract.

Unit leaks oil.

Cause

Low oil level.

Loose coupler
connection.
(WHC & WHR models)

Debris caught between
cutter head shear and
blade.

Fluid release lever not
working.

Seal damage caused by
overloading cutter or by
normal use of cutter
over a period of time.

Solution

Be sure reservoir is filled with Enerpac oil.

Be sure all coupler connections are complete. Loose
or incomplete coupler connections will cause complete
or partial blockage of oil flow.

Remove blade screw from piston to release pressure.
Remove cutter head latch pin or spring latch to free
blade.

Clean the blade and blade track. Hone the blade. See
Maintenance step 6 on page 4. Lubricate the blade
and track with silicone spray.

See illustration below. Place wooden wedge against
the release pin and lightly strike wedge with a
hammer. The lever should release forward to by-pass
and relieve pressure.

The blade should retract. If debris is caught between
the blade and cutter head, disassemble and clean as
described above.

Replace seals. Seals are available as part of the
Repair Kit for your cutter. An Authorized Enerpac
Service Center can perform the repairs for you.

Place wooden wedge
behind release lever.
Use wood or other
soft material to avoid
damaging cutter body.

MAINTENANCE

Perform maintenance regularly to keep your hydraulic cutter in good operating condition.

1. Clean dirt from cutter using grease solvent.

2. Lubricate the head and blade with silicone spray rather than
oil. Oil attracts dirt, silicone does not.

3. Keep reservoir full of clean oil. Drain all oil and refi ll with
clean Enerpac oil every 12 months. Change oil more often
under dirty environmental conditions.

Dispose of used oil properly.

4. If cutter has been used under water or in severe conditions,
wash the cutter and lubricate immediately. Remove and clean
the handle cylinder.

5. Repaint unit as necessary. If cutter is used in water regularly,
repaint it with light colored corrosive resistant paint.

6. Keep blade and cutter head shear sharp. Hone blade by
rubbing a sharpening stone across the blade on the fl at side
(not the knife edge side).

Keep the stone fl at and parallel to the blade. Keep back bevel
to a minimum, or blades will separate and break.

Discard cracked or chipped blades. New blades can be
purchased separately.

7. Fluid leakage is usually the result of overloading the cutter
and damaging the seals. Repair kits are available. Repair kits
include piston seals, latch spring or pin, and blade screws.
Contact your local Authorized Enerpac Service Center if your
cutter needs to be repaired.

TO PROTECT YOUR WARRANTY, USE ONLY ENERPAC HYDRAULIC OIL.
