The force of the clamping spring 6 is, dependent on the thickness of
the underthread used, to be set so that the thread can be pulled under
it without hindrance. The underthread must, however, be held so tight
that a secure and drawn tight seam beginning is achieved.
The gimp must let itself be drawn unhindered under the clamping
spring 3. Thereby it should, however, be only very slightly clamped.
The deflector 1 is attached above the fixed knife 2. It prevents the
underthread end from entering between knife 2 and the back of the
thread catchers 7. It is instead guided next or in to the thread catcher.
If this does not occur the knife can be pressed down and not cut.
Caution Risk of Injury !
Pull the mains plug before adjusting.
