A copy of an EU Declaration of Conformity is
enclosed with each shipment of this product.
4.0 DESCRIPTION
The Enerpac model EBE22 is a fixed-head hydraulic
cutter designed to cut round, square or flat metal bars
and other similar items.
The cutter contains two blades, one fixed and one
moving. The moving blade is actuated by a hydraulic
cylinder.
Hydraulic force is provided by an AC powered electric
motor and an internal hydraulic pump. The pump
provides oil flow to the hydraulic cylinder, which
advances the cylinder piston and moving blade.
A hydraulic reservoir with built-in rubber diaphragm
provides a constant supply of oil to the pump, regardless
of tool orientation or the amount of piston extension.
A trigger style on-o switch, mounted on the cutter grip,
starts and stops the electric motor. The trigger must
remain pressed during the cutting process.
An automatic retract feature returns the piston to the
fully retracted “home” position when the piston reaches
its full stroke and the trigger is released.
A built-in blade safety guard provides protection from
splintered material during cutting and helps prevent
contact with the blades.
See Figure 1 for a description of cutter major features
and components. Refer to Sections 2.1 through
2.4 of this manual for maximum cutting capacities,
specifications and dimensions.

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.

10.2 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
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.
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, loosen the vent screw to provide
venting. Then, 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. Tighten the vent screw (if loosened).
11. Using a clean rag, wipe the cutter housing, grip and
motor so that these surfaces are free of oil residue.
12. 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.
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 8D 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 start-up during the following
steps.

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.
3. Disconnect the cutter from the AC power supply to
prevent accidental motor start-up during the following
steps.
4. 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.
5. To prevent contamination, remove any built-up dust
and dirt from the oil reservoir cap, diaphragm cover,
and surrounding area.
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.
6. Using an adjustable face spanner wrench, loosen and
remove the diaphragm cover.
7. Remove the diaphragm element from the diaphragm
opening.
8. Loosen and remove the oil reservoir cap.
9. Completely drain all old oil from the cutter, 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
oil reservoir cap facing up.
11. Loosen the vent screw to provide venting.
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.
12. Using the oil dispenser prepared in step 1, slowly
add new Enerpac HF oil through the oil drain/fill
hole and diaphragm opening until oil level is up to
the top of the drain/fill hole.
13. Install and securely tighten the oil reservoir cap.
Leave the diaphragm element and diaphragm cover
removed.
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.
14. Connect the cutter to the AC power supply.
15. Cover the diaphragm opening with a rubber-gloved
hand to help prevent oil splashing.
16. 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.
17. Continue pressing and releasing the trigger in short
bursts as the piston extends. During this 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 4 for
piston release screw details.
18. While covering the diaphragm opening with a
rubber-gloved hand, retract the piston gently by
slowly loosening the piston release screw.
19. Tighten the piston release screw.
20. Place the soft metal bar (refer to step 2) into the
cutting head.
21. 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.
22. Disconnect the cutter from the AC power supply
to prevent accidental motor start-up during the
following steps.
23. Add oil through the diaphragm opening until the
bladder opening is nearly full.
24. Slowly install the diaphragm element in the
diaphragm opening. This should result in some oil
leakage from the vent screw, as well as from around
the diaphragm element.
25. Tighten the vent screw.
26. Install and securely tighten the diaphragm cover.
27. Loosen the piston release screw to retract the
piston. If piston is stuck, use the bar to manually
push the piston back until it retracts.
28. Remove the soft metal bar from the cutting head.
Do not discard the bar. It will be used again later in
this procedure.
29. Tighten the piston release screw.
30. Connect the cutter to the AC power supply.

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.
NOTICE:
WARNING
To avoid serious personal injury, stay
clear of cutting head and blades during the following
procedures.
31. Start the cutter and cycle the piston through several
advance and return strokes. Ensure that piston is
fully retracted when done.
32. Be sure cutter is positioned so that the oil reservoir
cap is facing upwards. Do not operate cutter for
several hours (preferably overnight) to allow any
remaining air to separate from the oil.
33. Place the soft metal bar (refer to step 2) into the
cutting head.
34. 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 in step 35.
NOTICE
If you cut completely through the bar, try again,
cutting as far as you can without making a full cut.
35. Disconnect the cutter from the AC power supply
to prevent accidental motor start-up during the
following steps.
36. Loosen and remove the oil reservoir cap. Recheck
the oil level in the oil drain/fill hole. If oil level has
dropped, loosen vent screw and add additional
Enerpac HF oil until the oil level is up to the top of
the hole.
37. Install and securely tighten the oil reservoir cap.
38. Tighten the vent screw (if loosened).
39. Using a clean rag, wipe the cutter housing, grip and
motor so that surfaces are free of oil residue.
