Pinching risk of the workpiece

Note that there is a pinching risk between the ends 

of the workpiece, see figure.

Emergency stop

This machine is equipped with two emergency stop functions, i.e. one emergency stop on the electrical 

cabinet and one emergency wire running around the machine at foot height. This together with the fact 

that the machine is equipped with brake motor enables the machine to stop instantaneously in case of 

injury or risk of injury no matter where you are around the machine.

Service and maintenance

Before service and maintenance are carried out on the machine you must have had instructions from 

your foreman. You must also read and understand this instruction manual. Disconnect the main switch 

before the service job begins. If the machine must be dismantled, completely or partly, contact your 

foreman.

Protective clothing

Important! Never use gloves when bending, as this consider-

ably increases the risk of getting pinched between the rolls. 

For other handling of the workpieces use gloves. The operator 

must not carry belts, rings or necklaces.
Working shoes with steel inserts must be used.
Loose hanging clothes must not be used.
If the operator has long hair, this must not hang loose.

Deburring of the workpiece

Burrs and sharp edges must be removed from the workpiece before bending.

Jamming

If for some reason the machine stops while 

bending a workpiece, proceed as follows:
•  Crank down the bottom roll and possibly also the bending roll.
•  Remove the workpiece. Identify the trouble reason. If the motor protection is released, 

wait for some minutes before it is reset. The machine is then ready for use again.

•  If the trouble is mechanical or electrical: Cut the current and contact the supervisor.
