3.0 CONFORMANCE TO NATIONAL AND
INTERNATIONAL STANDARDS
Enerpac declares that this product has been
tested and conforms to applicable standards
and is compatible with all CE requirements.
A copy of an EU Declaration of Conformity is
enclosed with each shipment of this product.
4.0 DESCRIPTION
The Enerpac cordless bar cutters, models EBC20B and
EBC20E, are designed to cut round, square or flat metal
bars and other similar items.
These cutters contain two blades, one fixed and one
moving. The moving blade is actuated by a hydraulic
cylinder.
Power is supplied by an 18 or 20 volt lithium-ion battery
(varies by region). The battery powers a DC electric
motor, which drives a small hydraulic gear pump. The
pump provides oil flow to the hydraulic cylinder, which
advances the cylinder piston.
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 moves 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.
The rotatable cutting head can be turned 360 degrees,
allowing it to be positioned as needed for added
convenience.
See Figure 1 for a description of cutter major features
and components. Refer to Sections 2.1 through
2.6 of this manual for maximum cutting capacities,
specifications and dimensions.

Figure 11, Positioning Handle and Lifting Eye
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 8.
Position the material to be cut between the cutter
blades, so that it is perpendicular to the piston axis, as
shown in Figure 12. This will provide the best quality cut
while placing the least amount of load on the cutter.
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 hardness, tensile strength
and diameter of the material do not exceed any of the
stated maximum 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. Be certain that a battery is installed on the cutter and
that the battery has sucient charge to complete the
cutting operation.
2. Be sure that the piston is in the “home” (fully retracted)
position. See Figure 8.
3. Be sure that the piston release screw is turned fully
clockwise. See Figure 9.
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 on-o trigger to start the motor
and begin cutting.

10.5.1 Hydraulic System Maintenance Precautions
NOTICE:
WARNING
Always remove battery from cutter 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 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 Figure 14 and Figures 15A through 15C 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. Remove the battery to prevent accidental motor
startup during the following steps.
3. Place the cutter on a stable and level work surface,
with the oil reservoir cap facing straight up. Note that
the cap does not face straight up when the tool is
laid on a flat surface, so positioning aids are required.
Place a pan or suitable container under the cutter to
catch any spilled oil.
NOTICE
The oil reservoir cap is located just below the
on-o trigger when the cutter is positioned in the
inverted (upside-down) position. Be certain to remove
only this cap in the next step. DO NOT remove the relief
valve by mistake. See Figure 14.

Key:
1. Oil Reservoir Cap
2. Relief Valve
(DO NOT remove)
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).

10. Using a clean rag, wipe the cutter housing, grip and
motor so that these surfaces are free of oil residue.
11. Insert the battery. 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 Figure 14 and Figures 15A
through 15D:
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.

19
(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 9 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. Remove the battery to prevent accidental motor
startup during the following steps.
23. Add oil through the diaphragm opening until the
diaphragm opening is nearly full.
24. Slowly install the diaphragm in the diaphragm
opening. This should result in some oil leakage from
around the diaphragm.
25. Install and securely tighten the diaphragm cover.
26. 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.
27. Remove the soft metal bar from the cutting head.
Do not discard the bar. It will be used again later in
this procedure.
28. Tighten the piston release screw.
29. Insert the battery.
NOTICE:
WARNING To avoid serious personal injury, stay
clear of cutting head and blades during the following
procedures.
30. Start the cutter and cycle the piston through several
advance and return strokes. Ensure that piston is
fully retracted when done.
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. Ensure the piston is completely retracted.
4. Remove the battery to prevent accidental motor
startup during the following steps.
5. Place the cutter in the horizontal position, on a stable
and level work surface, with the oil reservoir cap
facing up. It is not critical that it face straight up, as
in the oil check procedure. Place a pan or suitable
container under the cutter to catch any spilled oil.
6. 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.
7. Loosen and remove the oil reservoir cap.
8. Using an adjustable face spanner wrench, loosen and
remove the diaphragm cover.
9. Remove the diaphragm from the diaphragm opening.
10. 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.
11. After all oil is evacuated, position the cutter with the
diaphragm opening facing up.
12. Install the oil reservoir cap.
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.
13. Using the oil dispenser prepared in step 1, slowly
add new Enerpac HF oil through the diaphragm
opening until oil level is up near the top.
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. Insert the battery.
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

20
31. Be sure cutter is positioned so that the oil reservoir
cap is facing straight up. Do not operate cutter for
several hours (preferably overnight) to allow any
remaining air to separate from the oil.
32. Place the soft metal bar (refer to step 2) into the
cutting head.
33. 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.
34. Remove the battery to prevent accidental motor
startup during the following steps.
35. Loosen and remove the oil reservoir cap. Recheck
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.
36. Install and securely tighten the oil reservoir cap.
37. Loosen the piston release screw to retract the
piston. If the piston is stuck, use the bar to manually
push the piston back until it retracts.
38. Using a clean rag, wipe the cutter housing, grip and
motor so that surfaces are free of oil residue.
39. Insert the battery. Cycle the piston several times to
test for proper operation before placing the cutter
back into service.
10.6 Cutter Blade Replacement
NOTICE:
WARNING
• Always remove battery from cutter 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.
