Keep persons away from cutting area.
• Cutter surfaces can become very hot. To prevent
burns, avoid contact with cutter components and
wear appropriate personal protective equipment.
• Refer to additional safety precautions in Section 1.0
of this manual before using the cutter or performing
any maintenance or repair activities.
9.3 Trapped Air Removal
Before placing a new cutter into operation, cycle the
piston several times without load to remove any trapped
air in the hydraulic circuit.
Air is completely purged when the piston advances and
retracts smoothly in both directions, from fully advanced
to fully retracted.
This procedure should be performed after the oil in the
cutter is changed, and after any maintenance or repair
activity in which the oil is drained and replaced.
9.4 Locating and Positioning the Cutter
• Before inserting material to be cut inside the cutting
head, be certain that the cutter is placed on a solid
and stable work surface of sucient weight rating
capacity. Refer to Section 2.2 for cutter weight.
• Position the cutter as needed using the handle/grip
mounted at the top of the cutter. The handle/grip
can also be used for transporting the cutter short
distances.
NOTICE:
WARNING
Because the cutter components are very
heavy, there is a risk of cuts, crushing or broken bones. To
avoid accidents, use care when working with the cutter.
Serious personal injury may result if the cutter is not
properly supported and handled in an appropriate way.
9.5 Positioning Material Inside the Cutting Head
Be sure that the piston and moving blade are located in
the fully retracted “home” position before placing any
material inside the cutting head. See Figure 4.
Position the material to be cut between the cutter
blades, so that it is perpendicular to the piston axis, as
shown in Figure 6. This will provide the best quality cut
while placing the least amount of load on the cutter. If
possible, center the material vertically to help reduce
side-loading of the piston.
Adjust the support bolt as needed. The head of the
support bolt should just touch the surface of the material
to be cut, when the item is positioned against the fixed
blade of the cutter.
After adjusting the support bolt, be sure that the support
bolt retaining nut is snug tight against the support
bolt mounting ear. This will help prevent support bolt
movement during cutting.
NOTICE
Be certain that the maximum parameters of the
material to be cut are within allowable limits. Refer to
Section 2.1 of this manual for additional information.
Failure to observe this instruction may result in poor
cutting performance and/or damage to the cutter.
9.6 Cutting Procedure (typical)
1. Connect the cutter to the electrical outlet.
2. Be sure that the piston is in the “home” (fully retracted)
position. See Figure 4.
3. Be sure that the piston release lever is turned fully
clockwise to position 1. See Figure 5.
4. Place the material to be cut between the fixed and
moving blades. Refer to instructions in Section 9.5 for
additional information.
NOTICE
Position the item to be cut so that it is as
perpendicular as possible to the blades, as described in
Section 9.5. Positioning the material at an angle will
side-load the piston. Jamming and/or damage to the
cutter may result.
5. Be certain that hands, fingers or other body parts are
not inside the cutting head.
6. Press and hold the trigger to start the motor and begin
cutting.
7. After cutting is completed, wait until the piston
reaches the end of its stroke and then release the
trigger. Verify that the moving blade reverses direction
and moves fully into the “home” (fully retracted)
position.

10.0 MAINTENANCE
10.1 Preparation for Maintenance
All cutter maintenance procedures must be performed
under the following conditions:
• Material must be removed from the cutting head.
• The cutter must be disconnected from the AC power
supply.
• The cutter must be given time to cool to prevent burns.
• Procedures must be performed in a suitable work
environment in accordance with all current safety
regulations and/or laws in your country or region.
• The cutter must be cleaned thoroughly before
maintenance procedures are performed.
• Suitable personal protective equipment (PPE) must be
used and/or worn while performing any work.
10.2 Periodic Maintenance Chart
Refer to the Periodic Maintenance Chart (Table 1) for a
list of various routine checks and procedures.
10.3 Cleaning
• Clean the cutter using a dry cloth or compressed air.
For plastic surfaces, use a cloth slightly dampened
with water.
NOTICE:
CAUTION
To prevent possible injury, always wear
safety glasses or face mask when using compressed
air.
• Be sure there are no traces of oil, grease or corrosive
substances on the tool, especially on the grips.
• Use a damp cloth and soapy water to clean plastic
components.
• Do not use gasoline or thinner to clean the tool.
10.4 Fasteners
Periodically check all screws, nuts and other fasteners
for proper tightness. Tighten any loose fasteners.
Replace any worn or damaged fasteners. This should
be performed periodically or every day in the event of
frequent or prolonged cutter operation.
NOTICE
Failure to check and tighten fasteners as
required may result in serious damage to the cutter.
10.5 Cutter Hydraulic System
The cutter contains a small hydraulic pump and an oil
reservoir with a rubber diaphragm. The oil level must be
periodically checked and additional oil must be added if
the oil level is low. In addition, the oil must be completely
changed at the specified interval. Refer to the Periodic
Maintenance Chart (Table 1).

13
4. To prevent contamination, remove any built-up dust
and dirt from the oil reservoir cap and surrounding area.
NOTICE
A small amount of hydraulic oil may leak from
the drain/fill hole when cap is loosened in the next step.
Be prepared to catch this oil in a pan or with a clean rag.
Dispose of spilled oil in accordance with all applicable
laws and regulations.
5. Slowly loosen the oil reservoir cap while watching for
oil flow:
• If oil starts flowing from the oil drain/fill hole as the
cap is loosened, the reservoir is full. Tighten the
cap immediately. To avoid excessive oil spillage,
do not continue loosening the cap if oil flow
occurs. Skip steps 6 through 8 and go on to step 9.
• If no oil flow occurs when the cap is loosened,
fully loosen and remove the cap. Then, check
oil level and add oil (if needed) as described in
steps 6 through 8.
6. Check the oil level in the drain/fill hole. Oil level will be
up to the top of the hole when reservoir is full.
7. If oil level is low, slowly add new Enerpac HF oil
through the oil drain/fill hole, until the oil level is up to
the top of the hole.
8. Remove any residue or metal particles from the oil
reservoir cap (it is magnetic).
9. Install and securely tighten the oil reservoir cap.
10. Using a clean rag, wipe the cutter housing, grip and
motor so that these surfaces are free of oil residue.
11. Connect cutter to AC power supply. Cycle the
piston several times to test for proper operation
before placing the cutter back into service.
10.5.3 Changing the Oil
NOTICE
The oil change procedure is very detailed and
will take a considerable amount of time. It should only
be performed by a trained technician at an Enerpac
authorized service center. Failure to properly perform
the procedure may result in incomplete filling of the
cutter oil reservoir, which could lead to cavitation, air
entrainment, reduced performance, and pump damage.
Change the oil in the cutter reservoir as described in the
following steps. Refer to Figures 8A through 8E:
1. Fill a clean oil dispenser with new Enerpac HF oil. Put
the dispenser aside for later use.
2. Procure a thick, soft metal bar (about 1/4 inch
[6.4 mm] minimum thickness). Put the bar aside for
later use.
NOTICE
The bar selected should be easy to cut, but not
brittle. The bar material must be soft enough so that the
bar will not break into two pieces before it is fully cut.
Later in this procedure, the bar will be partially cut so
that it becomes lodged in between the jaws of the cutter
without being cut through completely, as the piston is
extended to slightly less than maximum travel.
10.5.1 Hydraulic System Maintenance Precautions
NOTICE:
WARNING
Always disconnect cutter from AC power supply
before performing hydraulic system maintenance.
Failure to observe this precaution could result in
accidental startup while maintenance procedures
are being performed. Serious personal injury and
damage to cutter may result.
Wait for cutter to cool before performing hydraulic
system maintenance. Hot oil can cause burns.
Be sure that oil reservoir cap is securely tightened
after checking oil level or changing the oil. Leaking
oil can cause short circuits, fire and explosions.
Additional Precautions:
• Do not check oil level or change the oil in dusty areas.
• Be sure that all tools (wrench, screwdriver, etc.) used
to perform maintenance procedures are clean.
• When adding oil and performing oil changes, take every
precaution to prevent impurities from contaminating
the oil or entering the cutter. Impurities can cause
permanent damage to the hydraulic components.
• The hydraulic reservoir contains a rubber diaphragm
that slightly pressurizes the oil. Some oil spillage may
occur when checking the oil level or when changing
the oil. Wear and/or use appropriate personal
protective equipment (PPE) to prevent exposure to
hydraulic oil.
• Use only new Enerpac HF hydraulic oil poured from a
clean container. Use of other oil brands and/or used
oil may damage the cutter and may void the Enerpac
product warranty.
10.5.2 Checking Oil Level and Adding Oil
NOTICE
The reservoir contains a flexible rubber
diaphragm that slightly pressurizes the oil. To help prevent
excessive oil leakage when the reservoir cap is removed,
be certain that the piston is advanced until there is a gap
of about 1/8 inch [3-4 mm] between the fixed and moving
blades (as described in step 1) before loosening the cap.
The gap between the blades should not be less than
1/8 inch [3-4 mm]. A smaller gap may result in the
piston retracting unexpectedly while the oil level is being
checked.
Refer to Figures 8A through 8E during the following steps:
1. Operate the cutter and advance the piston until
there is a 1/8-inch [3-4 mm] gap between the fixed
and moving blades (until just before the piston
automatically returns).
2. Disconnect the cutter from the AC power supply to
prevent accidental motor startup during the following
steps.
3. Place the cutter in the horizontal position, on a stable
and level work surface, with the oil reservoir cap
facing upwards. Place a pan or suitable container
under the cutter to catch any spilled oil.

3. Disconnect the cutter from the AC power supply to
prevent accidental motor start-up during the following
steps.
4. Place the cutter in an upright position, on a stable and
level work surface, with the handle facing upwards.
Place a pan or suitable container under the cutter to
catch any spilled oil.
5. To prevent contamination, remove any built-up dust
and dirt from the oil reservoir cap, diaphragm cover,
and surrounding area.
NOTICE
When the handle is removed the wires from the
trigger on-o switch will still be connected to the electric
motor. Take care not to pull or stretch the wires when
removing the handle or when performing the oil change
procedure.
6. Remove the screws holding the tool handle in place.
Carefully remove the tool handle to gain access to the
diaphragm cover. The tool handle wiring will still be
connected, so use caution to avoid damaging this
wiring.
NOTICE
A small amount of hydraulic oil leakage may
occur when the diaphragm cover is removed in the next
step. Be prepared to catch this oil in a pan or with a
clean rag. Dispose of spilled oil in accordance with all
applicable laws and regulations.
7. Remove the diaphragm cover by removing the six
screws securing it.
8. Remove the diaphragm from the diaphragm opening.
9. Completely drain all old oil from the cutter through the
diaphragm opening, turning it upside down and using
a suitable oil extraction system (used oil extraction
pump) if necessary, so that no oil remains in the cutter
reservoir.
NOTICE
Dispose of all used oil in accordance with all
applicable regulations and laws.
10. After all oil is evacuated, position the cutter with the
diaphragm opening facing up.
NOTICE
Use only new Enerpac HF oil in the following
step. Use of other oils may damage the cutter and may
invalidate the Enerpac product warranty.
11. Using the oil dispenser prepared in step 1, slowly
add new Enerpac HF oil through the diaphragm
opening until the diaphragm opening is nearly full.
NOTICE:
WARNING
To avoid serious personal injury, stay
clear of cutting head and blades during the following
procedures. Wear rubber gloves to prevent contact
with oil. Wear eye and face protection to avoid injury
due to splashing oil.
NOTICE:
WARNING In the following steps, the tool must be
operated with the handle separated from the tool
housing. Use extreme caution to prevent injury as
service procedures are being performed.
12. Connect the cutter to the AC power supply.
13. Cover the diaphragm opening with a rubber-gloved
hand to help prevent oil splashing.
14. Prime the pump by pressing and releasing the
trigger in short bursts. During this process, check
the oil level in the diaphragm opening and add oil
(as needed) to keep the reservoir filled. Failure to
keep reservoir full may result in cavitation and
pump failure. Pump is primed when piston starts
extending.
NOTICE
During priming, the oil may become entrained
with air and may develop a foamy appearance. This is
normal.
15. Continue pressing and releasing the trigger in short
bursts as the piston extends. During this part of the
process, do not add oil, but verify that the pump has
ample oil supply. Continue until piston is extended
to approximately half stroke.
NOTICE
During the following steps, refer to Figure 5 for
piston release lever positions.
16. While covering the diaphragm opening with a
rubber-gloved hand, retract the piston gently by
slowly moving the piston release lever to position 2.
17. Move the piston release lever back to position 1 and
tighten.
18. Place the soft metal bar (refer to step 2) into the
cutting head.
19. Press and release the trigger in short bursts until
the piston is extended as far as possible, but before
it makes a full cut and retracts. The moving blade
will become lodged in the bar, preventing the
piston from retracting. This procedure is necessary
because the cutter mechanism alone may fail to
hold the piston in the partially extended position as
oil is being added in the following steps.
NOTICE
If you cut completely through the bar, try again,
cutting as far as you can without making a full cut.
20. Disconnect the cutter from the AC power supply
to prevent accidental motor start-up during the
following steps.
21. Add oil through the diaphragm opening until the
diaphragm opening is nearly full.
22. Slowly install the diaphragm in the diaphragm
opening. This should result in some oil leakage from
around the diaphragm.
23. Install the diaphragm cover and securely tighten the
six screws securing it.
24. Reinstall the tool handle. Be certain that electrical
wires are not pinched between tool housing and
handle.
25. Move the piston release lever to position 2 to retract
the piston. If piston is stuck, use the bar to manually
push the piston back until it retracts.
26. Remove the soft metal bar from the cutting head.
Do not discard the bar. It will be used again later in
this procedure.

10.6 Cutter Blade Replacement
NOTICE:
WARNING
• Always disconnect cutter from AC power supply
before beginning blade replacement procedures.
Failure to observe this precaution could result in
accidental startup during blade replacement. Serious
personal injury could result.
• Use extreme caution when removing and installing
blades. Blades may be sharp even when worn. To
avoid hand injury, wear appropriate personal
protective equipment (PPE) and avoid contact with
blade cutting edges.
10.6.1 Blade Wear
The use of worn blades decreases the eectiveness of
the cutter and can also side load the cylinder, resulting
in possible damage to the tool. Motor overheating can
also occur.
Replace blades immediately if they are worn and/or
damaged or if there has been a noticeable decrease in
cutting performance.
NOTICE
Blades are not sharpenable and must be
replaced when worn. To help ensure optimum cutting
performance, replace both the fixed blade and the
moving blade at the same time.
27. Move the piston release lever to position 1 and
tighten.
28. Connect the cutter to the AC power supply.
NOTICE:
WARNING
To avoid serious personal injury, stay
clear of cutting head and blades during the following
procedures.
29. Start the cutter and cycle the piston through several
advance and return strokes. Ensure that piston is
fully retracted when done.
NOTICE
Orient the oil reservoir cap facing upwards at
this time, and keep it as such until the cap is installed for
the final time. Failure to do so may result in air remaining
in the reservoir. This may require special consideration
when the soft metal bar is used.
30. Do not operate cutter for several hours (preferably
overnight) to allow any remaining air to separate
from the oil.
31. Place the soft metal bar (refer to step 2) into the
cutting head.
32. Press and release the trigger in short bursts until
the piston is extended as far as possible, but before
it makes a full cut and retracts. The moving blade
will become lodged in the bar, preventing the
piston from retracting. This procedure is necessary
because the cutter mechanism alone may fail to
hold the piston in the partially extended position as
oil level is being checked.
NOTICE
If you cut completely through the bar, try again,
cutting as far as you can without making a full cut.
33. Disconnect the cutter from the AC power supply
to prevent accidental motor start-up during the
following steps.
34. Loosen and remove the oil reservoir cap. Check
the oil level in the oil drain/fill hole. If oil level has
dropped, add additional Enerpac HF oil until the oil
level is up to the top of the hole.
35. Install and securely tighten the oil reservoir cap.
36. Move the piston release lever to position 2 to retract
the piston. If piston is stuck, use the bar to manually
push the piston back until it retracts.
37. Using a clean rag, wipe the cutter housing, grip and
