8.2. Bending Adjustments
Turn the switch (MAN/AUTO) to the MAN position, close the shield and push the material to
the direction of arrow by pressing the foot pedal down. Make adjustments both in diameter and
in pitch by means of the adjustment bracket and the bending slope. Make the adjustment of
diameter by means of turning the adjustment bolt and moving the adjustment roller forward
and back (Figure 4) (Closer the adjustment roller to the fixed roller smaller the diameter (D) of
the material is, and vice versa). To adjust the pitch (t) among the spiral circles lift the bending
slope up and down by means of the bolt underneath (Figure 4). Lower the slope smaller the
pitch is, and vice versa. Following the adjustments required shift the machine in AUTO position
and start to make serial bending (Figure 6).
Note: The rollers of the machine continue to turn as long as the foot pedal is pressed down.
The rotation of rollers stop if the foot pedal is stopped pressing. The rollers start to turn if the
foot pedal is pressed one time whilst the machine is on AUTO position. Press one time again
onto the foot pedal to stop it again.
