The sum of the selected fullness level and the stitch length must not exceed
4.5 because more than this lessens the stitch length.
When the left pedal is in resting position the machine sews with equal bottom
and top feed strokes. By activating the left pedal the level of fullness set on
adjustment wheel 1 is sewn into the top fabric layer (see chapter 7.03 Pedal).
