Threading of the right and left looper is
described on pages 8 and 9. The slide

The 3-thread overedge seam is sewn
with two looper threads and one needle
thread.
Seam width adjustments at adjustment
knob 26 (3 to 5 mm) only refer to the
right needle.
When the left needle is used, the set
value is increased by 2.2 mm (seam
width 5.2 to 7.2 mm).
