Caution: Risk of injury!
Turn off the main switch.
Check and set the thread regulator only when the machine is switched
off.
Standard checking
The position of the thread regulator 1 depends on the thickness of the
material to be sewn, the thread size and the chosen stitch length. It
has to be set so that the thread is guided around the hook and kept
under control.
In position "1" occurs the highest thread output, as needed with
particularly large stitch lengths and thick sewing threads.
–
Open the throat plate slide.
–
Thread in the needle and hook thread.
–
Insert the material.
–
Sew a few stitches.
–
Turn the handwheel slowly and observe how tight the thread is
guided around the hook.
Correction
–
Loosen screw 2.
–
Shift the thread regulator.
Thread regulator to the left = more thread.
Thread regulator to the right = less thread.
–
Tighten screw 2.
