● The cutter blade can get worn out by repeated rebar
cutting. Continued use of a worn-out cutter can
result in the damage and the broken pieces flying
around. Replace it with a new cutter after no more
than 5,000 times of cutting.
● The machine is so designed that the upper cutter
and the grip rubber can support a rebar.
If the grip rubber gets worn out, there is a fear that
it cannot sufficiently hold the rebar and gets broken
down with its parts flying around, etc.
If the grip rubber cannot hold the rebar much longer,
replace it with a new grip rubber. Also replace the
worn grip rubber with new one when replacing the
cutter.
● During cutting work, securely hook the rebar to the
reaction stopper B. Furthermore, secure enough
length of a rebar to be hooked to the reaction
stopper B.
● Avoid bringing your hand near to the reaction
stopper B during operation. If you do so, you may
get your finger caught in or may run the hazard of
other injuries.
● Set the rebar in the center or the recess of the cutter
during cutting work. Any cutting work with the
rebar set on corners or ends of the cutter can result
in the pieces of broken rebar flying around or the
damage to the cutter and the machine.
● If you bend the rebar with a large angle while placing
your hand onto it, there is a fear of getting your
hand caught in by the fold-back reaction of the rebar.
Never place your hand onto the position where the
rebar may fold back.
English

HOW TO USE (CUTTING)
1. Normal cutting (Fig. 5)
(1) Turn the lever in the direction of the arrow mark
and open the cover.
(2) Set the setting dial at the “cut” position. (Turn
the setting dial all the way clockwise.) (Fig. 6)
(3) Set the unit in the position shown in Fig. 5.
(4) Set the rebar to be cut on the lower cutter.
(5) When the rebar is set, make sure that the reaction
stopper B is hooked to the rebar.
(6) Pull the switch trigger and cut the rebar.
WARNING:
䡬 While turning switches, never put your hand close
to the cutter, reaction stopper, or bending roller.
䡬 Bringing your hand close to these components can
result in serious injury.
䡬 Do not cut any rebar exceeding the maximum
capacities of the unit described in the specifications.
䡬 Never cut any hard materials such as PC(Precast
concrete) steel. Materials of this type are likely to
scatter into pieces and cause injuries.
䡬 The rebar you are cutting may have a hard spot in
it. Quality may vary within each rebar. Do not
attempt to cut NON-GRADE rebar.
䡬 Replace the worn grip rubber with new one when
replacing the cutter.
䡬 Note that the unit is not a hand held tool. Be absolutely sure to use the unit only after
placing it on stable spots such as floor, ground, etc.
CAUTION:
Even after the cutting has been completed, continue pulling the switch trigger until the
motor starts to run in the reverse direction and the cutter starts to return. If the switch
trigger is released too early, the cutter will not return and the trigger will have to be
pulled again.
2. Removing the rebar during cutting operation.
(Fig. 7)
If the switch trigger is released in the middle of
cutting, the cutter can come to a stop at a halfway
position, jumming the rebar in the unit.

SERVICE LIFE AND REPLACEMENT OF THE CUTTER
1. Service life of cutter (Fig. 9)
Repeated cutting of the rebar can result in the
"wear and tear", "deformation", "nicked edges",
etc. Using the cutter under such circumstances will
not only damage the machine but also there will be
a fear of the broken cutter fragments flying around.
Replace it with a new cutter after cutting no more
than 5,000 pieces of rebar.
2. Before removing the cutter
(1) Pull the switch lightly and let the upper cutter
move slowly. When the hexagon socket bolt
that fixes the upper cutter comes out of the cam
cover, turn the switch OFF and stop the motor.
(2) Unplug the power cord from the receptacle.
3. Removal
䡬 If you remove the hexagon socket bolt using the
provided Allen key, you can remove the cutter.
(Pushing the cutter guard up in the direction of
the arrow shown in Fig. 10, facilitates removal
of the upper cutter.)
䡬 Removal of the lower cutter can be easily made
if the lower cutter is wrenched with a Phillips
head screwdriver as shown in the following
diagram. (Fig. 11)
WARNING:
䡬 To prevent accidents, always be sure to turn the
switch OFF and unplug the power cord from the
receptacle.
䡬 If you remove the hexagon socket bolt using the

CAUTION:
䡬 Install the cutter and accessories securely according to the instruction manual. If you fail
to install them properly, they may come off and cause an injury.
䡬 Be sure to unplug the power cord from the receptacle when the cutter is checked,
cleaned, and replaced. Failure to do so can result in a serious injury.
HOW TO USE (BENDING)
1. Setting bending angles by setting dial.
The bar can be bent according to the angles indicated on the setting dial, as shown in Fig.
12.
In bending the rebar of #3(3/8"), #4(1/2"), and #5(5/
8") diameters, a difference takes place in the bending
angle even in the same dial position depending
upon the difference of rebar's thickness. Slightly
change a position of the setting dial depending
upon the rebar's diameter even with the same
bending angle as shown in Fig. 13.
NOTE
Even at the same dial setting position, the bending angle can sometimes differ if the diameter
or hardness of the rebar is different. Use the angle marks merely as a rough guideline.

2. Ordinary bending.
(1) Set the unit in the position with the turntable up
as shown in Fig. 14.
(2) Make sure that the cover is closed.
(3) Set the setting dial at the desired angle. (Fig. 13)
(4) Place the rebar on the center plate and set it
correctly as shown in Fig. 14.
(5) Pull the switch trigger and bent the rebar.
(6) Continue pulling the switch trigger untill the
motor makes reverse rotation and the bending
roller starts to return. (Once the bending roller
starts to return, it will automatically return all
the way to the home position even if the switch
trigger is released.)(Fig. 15)
WARNING:
䡬 Make absolutely sure that the cutter cover is closed
when you don’t carry out the cutting work. If the
cover is kept open, the cutter can jam on foreign
objects and cause serious accidents. (Fig. 16)
䡬 Never bring your hand close to the bending roller
during operation.
䡬 If you bend the rebar with a large angle while
placing your hand onto it, there is a fear of getting
your hand caught in by the fold-back reaction of
the rebar. Never place your hand onto the position
where the rebar may fold back.
䡬 Do not bend any rebar exceeding the maximum
capacities of the unit described in the specifications.
Never bend any hard materials such as PC(Precast
concrete) steel. Materials of this type are likely to
scatter into pieces and cause injuries.
䡬 The rebar you are bending may have a hard spot in
it. Quality may vary within each bar. Do not attempt
to bend NON-GRADE Rebar.
䡬 Never place your hand onto the bending side of the
rebar. If you do so, your hand may be caught in the
mechanical parts.
䡬 Install the deflection guard for operation with the bending length of a rebar 20" (inside
dimension of the deflection guard) or less to protect the persons around the rebar cutter/
bender in case rebar splinters into pieces and deflects during bending. (Fig. 20)
䡬 Remove the deflection guard when bending a rebar whose bending length and the fixed
length are more than 20" to prevent damage to the deflection guard.
䡬 Replace the deflection guard with new one if it is damaged. Damaged deflection guard
cannot protect the persons around the rebar cutter/bender in case a rebar splinters into
pieces and deflects during bending.
䡬 Note that the unit is not a hand-held tool. Be absolutely sure to use the unit only after
placing it on a stable spots such as floor, ground, etc.

If the bending length is not long enough, the rebar
can come off during bending operation, or it can
break into fragments and scatter dangerously.
(Fig. 14)
䡬 Be sure to set the rebar in the roller correctly. If it
protrudes from the roller, the rebar can come off
during bending operation and scatter into pieces.
䡬 Bend less than every 3 pieces of rebar with a #3(3/
8") diameter, less than every 2 pieces with a #4(1/
2") diameter, and every 1 piece with a #5(5/8")
diameter.
䡬 Remember that the cutter moves even during the
bending operation, thereby, close the cutter cover
without fail.
3. How to install deflection guard
The deflection guard is provided to protect the persons around the rebar cutter/bender
in case a rebar splinters into pieces and deflects during bending. Install the deflection
guard to the VB16Y for operation with the bending length of a rebar 20" (inside dimension
of the deflection guard) or less.
(1) Insert the base of the deflection guard into the slot of the rebar cutter/bender. (Fig. 17)
(2) Open the guard fully by pulling the arms as shown below until a click is heard. (Fig.
18)
4. How to remove deflection guard
䡬 Reverse the installation procedure to remove the deflection guard.
5. How to use deflection guard
(1) Be sure to install the deflection guard when bending a rebar whose bending length
and the fixed length are 20" (inside dimensin of deflection guard) or less (Fig. 19)
(2) Be sure to install the deflection guard when bending a rebar whose bending length
is 20" (inside dimensin of diflection guard) or less and the fixed length is more than
20". In this case, move the arm at the fixed end. (Fig. 20)

(3) Remove the deflection guard when bending a rebar whose bending length and the
fixed length are more than 20" (inside dimension of the deflection guard).
CAUTION:
䡬 Set a rebar on the rebar cutter/bender so that the bending length is equal to or shorter
than the fixed length.
6. Bending by eye measurement.
Since the unit uses a variable-speed switch, you can bend the rebar to your desired angle
by eye measurement in addition to the dial setting.
(1) Set the setting dial to a larger angle than you
desire.
(2) Pull the switch trigger lightly and bend the rebar
slowly.
(3) When the rebar is bent to the desired angle,
stop pulling the switch. If the bar is still small of
the desired angle, pull the switch again.
(4) Remove the rebar after bending has been
finished. Then, pull the switch once more and
return the bending roller to the home position.
(Continue pulling the switch until the bending
roller begins reverse rotation.)
7. Removing rebar during bending operation
When bending out at a low speed in “bending by
eye measurement”, the rebar can sometimes get
caught in the bending roller due to its own flexure.
If this occurs, you can return the bending roller to
the home position by pulling the switch again after
setting the setting dial to the “return” position.
This is the same method used to remove the rebar
when it gets caught during cutting operation. (Fig.
21)
8. Using hole to fix unit in place.
A hole is provided at the center of the unit to fix and
stabilize it. This hole comes in quite handy when
used in the following manner. (Fig. 22)
䡬 For bending operation when the unit is fixed to
a work bench.
This hole will prove very convenient when the
unit is bolted to a suitable work bench.
(Bolt size M10, less than W3/8.)
