5.4.2 Setting of the knife position (turning) in
the sewing direction
When sewing models with big curves, the knife is to be set in
such a way, so that the trimming corner (B) in its front dead
centre is at the level of the needle when it enters into the
throat plate (standard setting).
When sewing models with corners and narrow inner curves,
the trimming knife is to be set behind the needle in such a
way, so that in the moment when the needle leaves the throat
plate and the trimming corner of the knife (B) is in its front
dead centre, there is a distance A between the needle and
the cutting corner of the knife , that is the width of the trimmed
edge.
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
Standard setting
-
Turn the shaft of the trimming drive using the ring (1), until
the trimming corner of the knife (B) gets the front dead centre.
-
Turn the hand wheel until the needle enters the throat plate.
-
Loosen the screws (2) and (3) and adjust the knife with the
holder (4) and the sleeve (5) as required.
-
Tighten the screws (2) and (3).
Setting for models with inner curves
-
Turn the shaft of the trimming drive by means of the ring (1)
until the trimming corner of the knife (B) gets into the front
dead centre.

Caution:
With any change of the knife position in the sewing direction,
we recommend to recheck the distance between the knife and
the throat plate insert, to correct eventually the distance in
accordance with 5.4.1.
5.4.3 Height setting of the knife
The bottom side (surface) of the knife (1) is to be set above
the sewn material in such a way, so that it enables a tight
passing above the material.
Caution! Danger of injury!

setting operation, wait until the motor stops!
