The upper (b) and lower (c) looper threads should
lock together on the rolled fabric edge. Adjust the
same as Overlock 3. See pages 50-52.
The fabric weight and fiber content may require
the SL (stitch length) to be adjusted. Stitch length
may be set from 1 to 4 (the higher the number,
the longer the length). Set a shorter stitch length
for lightweight or sheer fabrics. Set a longer stitch
length for heavyweight or bulky fabrics.

tighten lower looper thread tension (green).
