The presser foot pressure should be as weak as possible,
but strong enough so that the material does not slip.
1. Loosen the adjusting nut (1).
2. Turn the presser adjusting screw (2) to adjust the presser
foot pressure.
3. Tighten the adjusting nut (1).
At the time of thread trimming, the thread tension is
loosened and tension is applied by the pretension (1) only.
The standard trailing length for the upper thread is 35–40
mm.
If the tension of the pretension (1) is increased, the
lengths of the threads trailing from the needle tips will be
reduced; if the tension is reduced, the lengths will be
increased.
Adjust by turning the pretension (1).
