ELECTRICAL SAFETY
■
ALWAYS test the
POWER
switch on the equipment before
operating. The purpose of this switch is to shut down the
power.
■
NEVER use a extension cord that is frayed or damaged
where the insulation has been cut.
■
NEVER carry the equipment by its power cord or
disconnect it by yanking the cord from the power outlet.
■
ALWAYS make certain that the proper extension cord
has been selected for the job. See Extension Cord
Gauge Selection Table.
■
NEVER allow power cord to

while operating the equipment.
sure the receptacle circuit is connected to either a GFCI
receptacle or a receptacle protected by a 20 amp circuit
breaker.
■
When plugging the unit into a power receptacle, check
the nameplate for the correct operating voltage.
Operating the rebar bender at the wrong voltage will
damage the electrical components. ALWAYS read the
nameplate before applying power.
■
This unit is equipped with a 3-prong male power plug.
DO NOT use a 2-prong adapter when plugging into a
wall outlet. This will defeat the purpose of the ground
circuit. If the plug does not fit into the receptacle, contact
a qualified electrician to install a 3-conductor wall
receptacle (outlet).
■
Avoid body contact with grounded surfaces such as
pipes, radiators, ranges and refrigerators. There is an
increased risk of electrical shock if your body is
grounded.
■
DO NOT expose the hydraulic power unit to rain or wet
conditions. Water entering the power unit will increase
the risk of electrical shock.
■
When operating the unit outdoors, be sure to use the
appropriate outdoor extension cord. This type of
extension cord reduces the risk of electrical shock.
■
ALWAYS remove the AC power cord from the power
source before performing any service or maintenance
on the unit. This preventative safety measure reduces
the possibility of accidental starting.
When operating near an arc welder, it is important the
both the unit and the welding equipment be connected
to the same earth ground. If they are not, server damage
to the unit, particularly to the power cord could occur.
Personal injury may also occur.

GENERAL INFORMATION
GENERAL INFORMATION
The
MQ HBC19B/HBC25B Rebar Cutters
to be used as a portable on-site rebar cutter, capable of
cutting in-place rebar safely and efficiently with the squeeze
of a trigger. Labor time and injuries are greatly reduced
from manually cutting rebar. The cutter can virtually handle
any rebar cutting job, from slabs and masonry walls to large
buildings and bridges.
The rebar cutter contains a built-in hydraulic pump with
innovative magnetic particle filtering. All parts are machined
to tight tolerances for maximum performance.
are designed
At approximately 27 to 49 pounds, the cutter is easily carried around job sites. Even overhead work takes minimum
effort.
The cutting rod returns to the starting position when the
operating switch is released after the rod makes its full
cutting stroke. The cutting rod will not move if the cutting
stroke is not finished. The operating switched must be held
long enough for cutting rod to complete stroke.
The HC19B/HBC25B come with a return valve that allows
the cutter rod to return to the starting position when the
cutter blade jams and stops during cutting of a rebar.

OPERATION
CUTTING PROCEDURE
WARNING
Make sure that the bar is resting fully within the blades
and protector is in the upright position. If the rebar is
not properly set, the cutting piece or fragments of the
rebar may scatter as soon as rebar is cut and the cutter
can also be damaged.
1. Adjust the spacing bolt according to the diameter of
the rebar being cut. Bolt must allow rebar to be flush,
at 90° to the blades.
2. Connect the electric plug from the cutter to a proper
power source (115 volts, 60 Hz).
3. Place the rebar in the rebar holder. Rebar must rest
fully within the blades. See Figure 2. Position the
protector over the surface to be cut.
Figure 2. Rebar Placement
4. Tighten the spacing bolt and jam nut to hold the rebar
in place.
WARNING
Do not cut rebar when it is not properly supported by
the spacing bolt or if the spacing bolt is not properly
adjusted. When cutting, hold the rebar on the spacing
bolt side as shown below. If not, the cut piece may fly
off and cause serious injury to the operator or
bystanders.
NEVER use worn or damaged blades. Replace
immediately before using cutter again.
WARNING
Replace damaged (broken and cracked edge) or
deformed cutter as soon as possible. Damaged cutter
could cause the rebar to be get out of place or cracked
during cutting. This may cause a serious accident. Do
not cut rebar that is less than 8 inches (200 mm) in
length asthis may cause rebar to fly off and result to
personal injury.
CAUTION
5. Squeeze the ON/OFF switch to start cutting the rebar.
Keep holding the ON/OFF switch until the cuting rod
completes cutting cycle. Do not attempt to partially cut
through the diameter of the rebar. This will cause
damage to the blades and cause the rebar to fly out.
6. At the end of the cutting cycle, release the ON/OFF
switch. The cutter rod will retract automatically.
7. If cutter reaches 158° F or higher, stop cutting operation
and allow machine to cool before using again.
8. Periodically inspect oil level and electric motor brushes.
Refer to Maintenance section for details.
PAGE 10 — HBC19B/HBC25B REBAR CUTTER • OPERATION AND PARTS MANUAL — REV. #1 (03/07/12)
WARNING
Keep hands and face away from the blades
and other rotating or sliding parts during
operation.
RETURN VALVE OPERATION
The return valve is used when the cutter blade jams and
stops during cutting of the rebar.
1. Rotate the return valve half a turn in the
counterclockwise direction with the allen wrench (no. 4)
supplied with the unit. See Figure 3 for location.

MAINTENANCE
REPLACING OIL
The rebar cutter uses hydraulic action to operate. If there
is insufficient, dirty, or improper oil in the cutter, it will not
operate at full capacity. If unit is not operating properly,
check oil level and condition. If necessary, replace oil as
follows:
1. Loosen oil fill bolt with the supplied open-end wrench
Remove oil fill bolt and lay cutter to allow to oil to drain
out. See Figure 7.
