6. BELT
It is possible that, after a certain period of use, the bar feeder will indicate that the belt (A) requires
tensioning, via an on-screen message.
During the intervention, the belt must remain tensioned. If the belt and the toothed wheels
are misaligned, the motor will lose its reference points. In this case, reload the motor's
original reference points (see chapter 7). The same procedure applies if the belt is
replaced.

2. Open the protection cover.
3. Insert a lever (C) into the opening between the pulleys and push it against the motor, using the
frame as support.
4. Whilst supporting the motor, undo the retaining screws (B) .
5. With the lever (C) , push the motor upwards and then tension the belt (A) .
6. Keep the motor in this position and tighten the retaining screws (B) .
7. Remove the lever and close the protection cover.
