3.3 Direction of rotation on machine

3.4 Motor drive using tooth belts
3.4.1 Tension of toothed belt (Fig. 1)
C A U T I O N ! Danger of injury!
Switch off the machine at the mains when checking the belt
tension. Do not operate the machine without belt guard.
Otherwise DANGER of crushing fingers, of injuries to the body or
of pulling in of part of clothing.
The toothed belt should not be tensioned too much. You should be able to push
through it with light thumb pressure by about 5 mm.
Too little or too tight toothed belt tensioning can impair the positioning of the machine
and therefore impair the function sequence.
Tensioning the toothed belt (Fig. 1):
- Release the upper and the bottom retaining screw (1), (2) at the upper part of
the machine.
- Pull out the Sewing drive slightly and tighten the bottom retaining screw (2)
slightly.
- Tension the toothed belt by swivelling the Sewing drive.
- Tighten the upper and the bottom retaining screw (1), (2) again.
