Setting range 0:
General sewing
Setting range 1:
2.2 mm
Setting range 2:
• Does not operate during the first sewing cycle. Only applies to second and subsequent cycles (during underlay
sewing and overlap sewing).
This is used in cases such as when the rough edges of the material after cutting are hemmed by the buttonhole
stitches.
The cutter operates before the left zigzag stitch of the last cycle is sewn.
Setting range 3:
• Does not operate during the first sewing cycle. Only applies to second and subsequent cycles (during underlay
sewing and overlap sewing).
This is used in cases such as when the rough edges of the material after cutting are hemmed by the buttonhole
stitches.
It can also be used if the rough edges of the material block the buttonhole after the left and right zigzag stitches have
been sewn.
• The cutter operates immediately before the left zigzag stitch of the last cycle is sewn, and it operates again when the
front tack of the last cycle is sewn.

Operates immediately
is before the left zigzag stitch
of the last cycle is sewn.
Because the needle and knife positions are separated
by 2.2 mm as shown in the illustration, the distance
between the edge of the front tack and the edge of the
buttonhole cannot be set to less than 2.2 mm.
For example, if the knife Y space (A) is set to 0.5 mm,
the front tack length (B) will not go below 1.7 mm. At
such times, the front tack length can be set to less
than 1.7 mm when using cutting after sewing.
Once sewing is finished and material feeding has
finished, the cutter will operate.
