MOTORISED BACKROLL SAFETY SWITCH
The motorized back roll has a safety switch. When the roll is at its
lowest point the switch will stop the motor.

EXPLANATION FOR SAFETY SWITCH
The machine has been equipped with a security switch and wire for the operators safety When
the safety wire is pushed it pulls the below shown ring this act as emergency stop and stops all
machine activity
To restart pull the blue knob (shown by  in fig.1) while pulling the safety wire when engaged you
should see green (shown by  in fig.2) line under the blue knob. Now you can restart the machine
from control panel

ELECTRICAL CONNECTIONS
Warning :
All electrical connections must be performed and completed by a qualified electric
technician in order to minimize chance of personnel injury or damage caused by wrong connection.
The cable must be directly connected to the machine. No intermediates should be used. The
following pages contain the necessary diagram of electrical connections.
Ensure that the Electric Net is capable of loading up to V.Double-check the grounding for a
safe operation. ( look at electricity plan )
ROTATION OF MOTOR
After all the electrics have been completed, start the machine as below and check the
rotationary axis of the motor.
Bring Main Switch to Pos 1
Bring Key Switch to Pos 1
Push the foot pedal
Check the rotation direction axis of the motor
Reverse connect the electrics by qualified electric technician to achieve right rotation direction.
Note : When you push the button of up the roll on the commander control
panel, if rolls are moving up ( moving reverse position ) this means that motor is
moving the reverse position. We advise to change the electric cable connecting
points.

BENDING OPERATIONS
3 ROLL BENDING PRINCIPLES
Because of the heavy materials involved in bending, it must be done by qualified personnel
who have experience on such machines. Each step of the bending and pre-bending or conical
bending must be done very carefully. Remember that you can always make the radius tighter by
bending a little more but once you bend it too much there is no way of turning back.
Note: Before operating the machine, be sure that this manual is thoroughly read and
understood by the personnel who will directly operate the machine and others concerned with it.
PRE-BENDING OPERATION
Pre-bending is the operation where the edges of the material is bent to the same radius of the
end radius. This is used to get best results in full circle bending ( i.e. pipe making )or in operations
where there must not be any flat edges. According to the final radius to make the finished material
very good.
The pre-bending process is also different compared to 3 roll bending machines. The following
steps must be taken to make a pre-bending.
Before operation:
1. Clean the material and the rolls from dust, or grease
2. Make sure there are no chips or flame cutting left-over on the edges of the material
3. Keep in mind that if the material is cut by flame that side will be harder than the other side
4. Check the surface of the material carefully make sure its flat
5. It’s a good idea to have template of the required radius when making a bend. To make a template
cut a hard cardboard or cartoon piece with the necessary radius
6. Always work in the center of the rolls as shown below.
