INTRODUCTION
B 36 Mechanic Iron Bending Machine is made only with the purpose of steel material bending.
Using other than the indicated purposes are prohibited. It is possible to mount various apparatuses on
the machine optionally for bending in different shapes.
In order to obtain the best yield from the machine it should be in a situation so that it can be worked
easily and in a position that more productivity might be obtained from the operator. Because of this the
location where the machine is operated should be close to the iron stocks. Besides, it shall be more
useful to cover top of the location where the machine is operated with a shelter. We suggest two
workbenches to be located on two sides of the machine. Length of these workbenches should be as
long as the longest iron that will be bent. Since the operator will be able to work without turning,
lifting any kind of iron, it will enable the operator to work more effectively.
Important Warning !!!
•User's and maintenance manuals must be read.
•Machine should be operated by instructed workers.
•When adjustments such as controlling, maintaining, lubing are being made electricity of the
machine must be cut off.
•All of the explanations given under user's and maintenance manual must be complied.

2. MACHINE ASSEMBLY
•Machine should be leveled on a solid ground. Figure 2
•Electricity connection of the machine should be made by competent technicians.
Explanation
Electricity Connection
For main electricity connection plug should be connected to supply line with a 5x4 mm²
isolated cable and then plugged into power outlet.
Grounding connection should be made for safety. Machine shouldn't be operated without
making grounding connection.
Connection of grounding line
The following procedures should be followed for this system.
Connect one end of the grounding to a copper wire (minimum 16 mm²) as it will enable
electrical conductivity. The other end should be either connected with a pipe that has a conductivity
capacity immerged into the ground (preferably into a humid ground) or the copper plate should be
buried into the ground as much as deep.

3. MACHINE RUNNING PROCEDURES ORDER
•Be sure that the machine is assembled in conformance with the Machine Assembly procedures.
•If there is any object on the machine (including the bending apparatus) they must be removed.
•LEFT-RIGHT switch on the control panel of the machine is turned to LEFT or RIGHT position,
MAN AUTO switch is turned to MAN position and machine turning direction is confirmed by
pressing on the foot pedal.
Explanation: Rotation direction is approved by taking the front of the machine as reference (Control
pane side) the clockwise as right and counter-clockwise as left. If the machine is rotating reverse of the
switch it means phases of the electricity supply are feeding reversely. This situation doesn't affect the
running system of the machine. In such case LEFT-RIGHT switch might be turned to the other side or
competent electricians might change the directions of the phases.
After fixing the direction of rotation bending adjustments should start.

11.2. Bent Bar Bending setting (45°):
Prog. Off Normal Bending Setting Systems:
Before starting angle setting, it should be ensured that there is no any material on the machine
other than the bending equipment.
The Switch button should be taken to OFF position and P1 button should be pressed. There are
3 Switch Pins with same heights on the bending disc. Rotation direction should be controlled by taking
the machine to MAN position. Appropriate bending angle for venting should be set by trying the
switch pin (P1) (Figure 1-3) throughout the holes on the bending disc (A and B directions). As long as
the switch pins (A and B) are taken closer to the measurement sensor (Figure 1-4) from both sides, the
bending angle decreases. Conversely as they are taken away from the measurement sensor the bending
angle increases.
NOTE: For P1 button Switch pin=1; For P2 button Switch pin=2; For P3 button Switch pin=3 are used
to set the angle.
After the setting procedure is completed the iron for bending and bending equipment must be
put on the machine and it should be available for bending as it is shown in Figure 4a-4b-4c-4d . It
should be mounted according to the diameter (if it is smaller than 16 mm the retainer and if it is bigger
than 16 mm the appropriate bending sleeve) of the iron to be bent (Figures 4a-4b-4c-4d). Lastly when
the bending disc returns after bending the iron it should be mounted on the bending plate on the front
side of the iron for safety to prevent any injury due to movement of the iron. (Figure 10). Setting
process should be completed by ensuring the iron to be bent (Figures 4a-4b-4c-4d) positioned parallel
by moving bending plates backward and forward with the help of the adjustment spanner. (Figures 4a-
4b-4c-4d)
For serial bending, machine should be taken to AUTO position and then bending should be
made.
NOTE: When the machine is at the MAN position the bending disk revolves, after bending is
completed and the machine is on the holding position it stops. When the machine is at the AUTO
position bending disk stops at holding position by completing the bending just pressing the Foot Pedal
only once. When the machine is at the AUTO position, the machine can be stopped by pressing the

foot pedal as the bending process is started. The stopped machine might be turned to the starting point
back manually by continuously pressing the Foot Pedal and it is ensured to be turned to the automatic
mode again. Furthermore when the machine is at the AUTO position, Bending Disc might be stopped
by holding the Foot Pedal pressed while returning, after the bending process is completed. When the
foot pedal is released the machine restarts moving on the direction it stopped and stops at the zero
point. The specifications indicated for dangerous cases are used for Emergency stop and it is ensured
to protect the operator from the danger.
To change settings, bending process of the machine should be completed (zero point) in the
cases where the setting change is required by pressing P1-P2-P3 buttons and then the button required
to change the settings should be pressed. Otherwise settings aren't changed when the buttons are
pressed.
WARNING!!!When bending the iron the iron should be bent on bending apparatus with 5
times larger than the diameter of the iron to be bent.

11.5. Stirrup Bending:
Stirrup Bending Mode:
Prog. On Stirrup Bending Setting Systems:
PROGRAM OFF-ON SWITCH BUTTON should be at program ON position. 90° angle which is
used in stirrup bending should be set to P2 button before the program is taken to ON position, the
SWITCH BUTTON should be turned to program non position (clockwise) after the stirrup tip bending
with 135° are set to P3 button. After turning the SWITCH BUTTON, P1 button should be pressed
once. Afterwards P1-P2-P3 buttons will blink only once. This warning indicates that the machine is
ready for programming. After this process, programming starts according to the required bending
angle. For example: Programming for performing stirrup bending shape is described below.
(Figure 9-

Programming the described shape:
a) Press P3 button for once for the 1st angle,
b) Press P2 button three times successively for 90° bending in 2nd, 3rd and 4th angles.
c) The programming process for the 5th angle made after pressing P3 button is saved to the memory by
pressing the foot pedal and programming process is completed. After the setting procedure is
completed (Figures 13a-13b-13c-13d-13e-13f-13h-13h) bending order is followed and Stirrup
Bending should be completed.
NOTE: When the program ON-OFF SWITCH BUTTON is turned to ON position program is
reset and it must be re-programmed. The button should be switched to OFF position as long as it is not
needed. In case it is turned, the program should be redone as it is shown in the example.
NOTE: Iron that will be stirred up should be bent on an appropriate Bending Sleeve, Pin, Stir-up
pin or straight pin with at least 5 times bigger than the bending iron's diameter.
