11.1 Adjusting the needle thread regulator

The needle thread regulator determines the tension applied to guide
the needle thread around the hook. The required tension depends on
the thickness of the sewing material, thread strength, and stitch length.
Proper setting
The loop of the needle thread slides at low tension over the thickest point
of the hook, without forming loops or snagging.
