INTRODUCTION
MG20B Portable Rebar bending machine is only intended for bending the rebar. The utilization of it for all
purposes is prohibited, except this purpose.
In order to operate your machine better, the machine should be placed so as to be operated easily and in the
position which allows operator to work more productively. For this reason, the place, where the machine is
operated, should be close to the area where the rebar is kept. In addition to it, it will be useful that the roof of the
place, where the machine operates, is covered with shed. We recommend you to place the workbenches in the
both sides of machine. The length of those workbenches should be at the longest length of rebar which will be
bent. Since the operator may work easily by those benches without rotation, lifting all rebar, it shall allow
operator to work more productively.
Important Warnings !!!
The maintenance and user’s manuals should certainly be read.
Just the persons, who are adequately informed on it, should work with the machine.
While the machine is checked, maintained, lubricated, etc., the power of the machine should be cut off.
All instructions in the maintenance and user’s manual should be observed.

2. MACHINE ASSEMBLY
Machine should be leveled on a solid ground.Figure 2
Electricity connection of the machine should be made by competent technicians
Electricity Connection
For main electricity connection plug should be connected to supply line with a 5x2,5 mm²
isolated cable and then plugged into power outlet. ( maximum 25 mt. )
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 burried into
the ground as much as deep.

3. MACHINE RUNNING PROCEDURES ORDER
3.1. Energise and Rotation Determining of the Direction of Rotation
Ensure that the machine is settled up properly according to assemblying rules.
Empty the bending Tools on the machine before starting to bend.
Start the machine by Plugging it to the energy (Figure:1 No:3) and open the electric panel cover
(Figure:1 No:8) and switch the main switch (Figure:3 No:14) from “0” to “1” . on digital models,
switch “ON-OFF” button to “ON” position on the control panel.
Ensure that the power lamp on manual models and control pabel lamps on the digital models are
lighting after the machine is started.
Determine the direction of the rotation by switching the MAN-AUTO button to MAN position on
the control panel and by pressing the foot pedal. (Figure:1 No:4)
Take the front side of the machine as Reference, and the clockwise rotation of bending disc on
Figure:1 No:9 should be right and counter clockwise rotation should be left. Manufacturer
recommends the right side bending. If the bending disc is turning to left side, the phases coming
from the main electric network should be reverse. This situation does not affect the working system
of the machine. In case of facing the same, if the machine is a digital model, change the LEFT-
RIGHT posisition from the control panel or if it is manual model, change the direction of phases by
an experienced electrician.
Start to the bending adjustments after determining the direction of rotation.

Place the suitable stirrup head for your rebar, the straight pin and the bending sleeve (Figure:1
No:10,11,12) to the related holes of the bending dics.
Locate the switch pins on the small holes around the bending disc to adjust the bending angle .
(Figure:3 No:13)
Select the bending shape from the buttons on the control panel. (Figure:4 No:16,17,18)
On stirrup bendings, switch the PROG. ON-OFF button to (Figure4: No:19) “ON” position and
max. 9 different bending is adjusted at once and the bending can be done in the adjusted order.
After the adjustment is finished, switch the MAN-AUTO button(Figure:4 No:20) to AUTO
poisition and start to serial bending.
In case of an emergency, machine can be stopped by pressing the ‘emergency stop button2 on
thecontrol panel. (Figure:4 No:22) When you start to bend machine will re-start from the latest
adjusted programme.

Place the suitable stirrup head for your rebar, the straight pin and the bending sleeve (Figure:1
No:10,11,12) to the related holes of the bending dics.
Locate the switch pins on the small holes around the bending disc to adjust the bending angle .
(Figure:3 No:13)
Select the bending shape from the buttons on the control panel. (Figure:5 No:24,25,26)
Adjust the machine’s speed by the Speed Controller (Figure:5 No:31) Once the speed of the
machine decreased, the bending disc’s rotation speed will reduce and machine’s power (bending
capacity) will increase. And when the speed is increased the bending disc’s rotation speed will
increase and the machine’s power ( bending capacity ) will decrease.
As soon as the speed decreases the bending capacity will increase, and the speed increases the
bending capacity decreases.
On stirrup bendings, switch the PROG. ON-OFF button to (Figure5: No:27) “ON” position and
max. 9 different bending is adjusted at once and the bending can be done in the adjusted order.
After the adjustment is finished, switch the MAN-AUTO button(Figure:5 No:28) to AUTO
poisition and start to serial bending.
In case of an emergency, machine can be stopped by pressing the ‘emergency stop button2 on
thecontrol panel. (Figure:5 No:30) When you start to bend machine will re-start from the latest
adjusted programme.

3.4.Operation of 380V Digital Machine:
Place the suitable stirrup head for your rebar, the straight pin and the bending sleeve (Figure:1
No:10,11,12) to the related holes of the bending dics.
Press to SET button on the control panel and than to PROG button and enter the intended data. Use
the UP and DOWN arrows (Figure:6 No:39) and enter the intended angle degree to the angle
indicator. (Figure:6 No:37) Press the right arrow and switch to unit indicator (Figure:6 No:38) and
enter the intended unit. Once angle and unit data is entered press to down arrow and switch to SET
line. Enter the data to set line and save it by pressing to PROG button. Maximum 9 value can be
entered for each set line indicator.
After the adjustment is finished switch to MAN-AUTO button (Figure:6 No:34) to AUTO position
and start to serial bending.
After the bending finishes due to various steel quality entered data and bended angle should differ,
in case of such situations press to UP arrow for 15 seconds period. “100” or machine’s factory
settting “35” will appear on SET3 line’s angle indicator. Use UP and DOWN arrows and change
the angle as much as the bended angle difference and renew the calibration process by pressing the
PROG button.
In case of an emergency, machine can be stopped by pressing the ‘emergency stop button2 on
thecontrol panel. (Figure:5 No:30) When you start to bend machine will re-start from the latest
adjusted programme.
