OPERATION
CAUTION
Pull out battery before carrying out any adjustment,
servicing or maintenance.
When fi nished with a job, pull out the battery.
1. Switch operation
This product is equipped with a switch lock to prevent
inadvertent switch operations. (Fig. 7-a)
Pressing the switch lock in one of the indicated directions
and pulling the switch will activate the motor.
Once the switch is activated, it will remain on even after
releasing the switch lock as long as you are pulling on
the switch.
Releasing the switch within area Ⓐ will apply a brake
that will stop operation. (Fig. 7-b)
Releasing the switch within area Ⓑ will automatically
return the upper cutter and bending roller to their original
positions. (Fig. 7-b)
WARNING
The cutter also simultaneously activates, so please
close the cover. (Fig. 7-b)
2. Reverse-rotating the cutter and bending roller
Releasing the switch during operation could result in
the cutter and bending roller coming to a standstill to
sandwich the rebar and irremovably lock it in place.
(Fig. 8)
In this situation, the motor should be reverse-rotated to
return the cutter and bending roller back to their original
positions.
Below are the two methods for returning the cutter and
bending roller during operation.
● Set the setting dial on "RETURN" (Fig. 8-a)
(1) Align the setting dial on "RETURN".
(2) Pulling the switch again will activate reverse-rotation
mode.
When the tool begins returning, it will return to its original
position when the switch is released.
● Press the Manual Mode switch (Fig. 8-b)
(1) Press the Manual Mode switch.
(2) Pulling the switch again will activate reverse-rotation
mode.
The tool will return while the switch is pulled, and it will
stop when it returns to its original position.
(3) Once returned to the original position, press the Manual
Mode switch to return to "Normal Rotation Mode".
NOTE
The tool will not operate if left in Reverse-rotation mode,
so press the Manual Mode switch to cancel reverse
rotation.
HOW TO USE (CUTTING)
WARNING
○ 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 fl oor, ground, etc.
○ Never bring your hand close to the cutter during
operation.
○ Never bring your hand close to the reaction stoppers A
and B during operation.
1. Inspect the cutter and grip rubber
WARNING
○ Confi rm that the hexagon socket bolt attaching the cutter
is tight.
If the tool is used with the bolt loose, it could damage the
tool or the cutter and result in accident or injury.
○ 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 suffi ciently hold the rebar and gets broken down
with its parts fl ying around, etc.
If the grip rubber cannot hold the rebar much longer,
replace it with a new grip rubber. (For replacing the grip
rubber and repairing, ask the store where you purchased
it or the HiKOKI Authorized Service Center.)
(1) Position the tool as shown in Fig. 9.
(2) Attach battery and battery cover. (Fig. 10)
(3) Open the cover. (Fig. 12)
(4) Lower the upper cutter.
Lightly pull the switch and slowly move the upper cutter.
When the upper cutter comes outside the cam cover and
the hexagon socket bolt is fully visible, release the switch
to stop it in that position. (Fig. 13)
(5) Detach the battery cover and battery. (Fig. 11)
(6) Check for abnormalities such as wear, deformation or
breaks in the cutter. (Fig. 14)
If the cutter needs to be exchanged, see "3. Cutter
Replacement".
(7) Using the included hexagonal bar wrench, make sure
that the hexagon socket bolt is fully tightened. (Fig. 15)
(8) Make sure the grip rubber isn't worn down (Fig. 16)
(9) Make sure that the switch lock is in the lock position
(Fig. 17)
(10) Attach battery and battery cover (Fig. 10)
2. Cutting
WARNING
○ Do not cut any materials other than the rebars. If you
attempt to do so, the material can splinter into pieces
and scatter.
○ The bending roller moves even during cutting operation.
Never bring your hand close to the bending roller.
○ The cutter blade can get worn out by repeated cutting of
the rebar. Continued use of a worn-out cutter can result
in the damage and the broken pieces fl ying around.
Replace it with a new cutter after approximately 8000
times of cutting as a rough guide.
○ During cutting work, securely
hook the rebar to the reaction
stopper B. Furthermore, secure
enough length of the rebar to be
hooked to the reaction stopper B.
○ 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 fl ying around or the damage to the cutter and the
machine.
CAUTION
○ Do not simultaneously cut two rebars measuring
D16 mm or D13 mm.
Doing so may damage the tool.
○ A slip clutch is built in the machine to protect the
mechanism.
If you process the material with the diameter or quality
beyond the capacity, the slip clutch can sometimes
function. In such a case, stop processing immediately
and check the material.
When the slip clutch works, a big slip noise occurs, but
it's not a malfunction.
After following the steps for "1. Inspect the cutter and grip
rubber" (steps (1) through (10)), follow the instructions
below.
(1) Position the setting dial in the "CUT" position. (Fig. 18)
(2) Set the rebar to be cut above the lower cutter
Make sure that there is enough length for the rebar to
fully hook reaction stopper B. (Fig. 19)
(3) Press the switch lock in either direction to release the
lock, and pull the switch to cut the rebar. (Fig. 7)
After cutting the rebar, hold down the switch until the
motor completes its reverse-rotation and the upper
cutter begins its return.
