READ ALL INSTRUCTIONS AND SAVE
THIS DOCUMENT FOR REFERENCE.
1. Keep hands away from all moving parts and roll-
ers while operating.
2. Dress properly. Loose clothing or jewelry can
get caught in moving parts. Wear sturdy boots
with non-skid soles. Steel toed boots and safety
glasses are recommended.
3. Keep children and bystanders away. Distractions
can cause you to lose control.
4. Do not overreach. Keep proper footing and bal-
ance at all times. is enables better control of
the power tool in unexpected situations.
5. Stay alert. Watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the inuence of drugs or alcohol. A moment of
inattention while operating power tools may re-
sult in serious personal injury.
6. Do not exceed the maximum number of bars
that can be bent at one time. Please refer to the
Rebar Bender Roller Selection Chart
7. When positioning the bar between rollers, make
sure to lay it at on the machine surface. Failure
to do so may cause the rebar to y out.
8. Do not expose tool to rain or use in damp loca-
tions. Do not use tool in presence of ammable
liquids or gases. Keep work area well lit. If the
tool is used outdoors, keep it covered when not
in use and protect it from rain or water.
9. Do not try to bend materials harder than “Grade
60 or 600N/mm2” as they will either crack and
y out or cause machine failure.
10. Disconnect tool from receptacle when not in use.
Disconnect the tool when servicing or changing
rollers to prevent accidents.
11. Keep tool clean at all times for best and safest
performance. Follow instructions for lubricat-
ing and changing parts. Keep hands dry and
free of oil or grease. Inspect switches, tool cords
periodically and have them repaired or replaced
by an authorized service center if damaged.
Check moving parts for alignment and binding
as well as for breakage and improper mount-
ing. Damaged parts should be repaired or re-
placed by an authorized service facility unless
otherwise indicated in this instruction book.

bar. For #3, #4 and #5 stirrup hooks it’s only 4 times

CHANGING ROLLERS OR ACCESSORIES.
WARNING: ALWAYS UNPLUG TOOL
BEFORE CHANGING ROLLERS
1. Select and set the correct rollers for the bars to
be bent. See Rebar Bender Roller Selection
Chart
2. Plug the electrical power cord into an appropri-
ate outlet.
3. Lay the bar on the machine surface between
the center roller and bending roller. Adjust the
stopper so that the bar is parallel to the front
edge of the machine.
4. Turn the main switch on and check that the
pilot lamp has lit up.
5. Set the angle and make a test bend. If the bent
angle is not exact, adjust the angle setter slightly
to the right or le. Lock in the angle stoppers to
duplicate the same angle each time.
6. Push the operation button or foot switch. e
moving bending roller will automatically return
to the start position once the bend has been
completed.
7. If it is necessary to stop the machine in an
emergency, push the emergency stop button or
release your foot from the foot operated switch.
e bending roller will return to the start posi-
tion automatically.

before starting the operation.
2. Aer operation is completed, be sure to remove
metal dust, dirt, oil, etc… adhering to the ma-

3. In order to empty the metal dust from the
bender, remove side cover (DBD-25X and
DBD-32X models) then tilt the machine to one
side allowing the debris to fall out of the catch
pan. Be sure to blow out any remaining dirt
and dust with compressed air prior to using the
tool again (wear safety goggles to block blowing
debris).
