If the supplementary thread tensioner is open, the state of the

sewing foot lift does not change.

If the machine is turned off, the supplementary thread tension

remains at its previously set state.

6.6 Adjusting the thread regulator

The thread regulator (2) is used to c ontrol the quantity of needle thread

required by the stitch formation.

The best sewing results can only be ensured when using a precisely

adjusted thread regulator.

–

Loosen the screw (1). Move the thread regulator (2). Then tighten

the screw (1).

–

For most sewing jobs, the thread regulator is best positioned when

the right edge of the regulator is aligned with the number 3.

–

The setting at position 4 is appropriate when using a thin sewing

material with a very short stitch.
