7.11 Adjusting the stitch width

• Needle position
• Cutting width

Changing the stitch width via the needle position

The stitch width can vary by the choice of needle position by 2 mm.
> To sew a wide stitch, insert the left needle.
> To sew a narrow stitch, insert right needle.

Changing the stitch width via the cutting width

The stitch width can vary by adjusting the knife position. The scale of the cutting width dial determines the
distance between the left overlock needle (LN) and the knife in mm. For the right overlock needle, the set
scale value is reduced by 2 mm.
> To adjust the stitch width, set the cutting width dial between 5 − 9 mm.
7.12 Adjusting the stitch length
The stitch length setting corresponds to the feed dog movement in mm.
The common stitch length for overlock stitches is 2.5 mm, for coverstitches 3.5 mm and for combo stitches 3
mm. Stitch lengths of approx. 1 mm are e.g. used for rolled hems, while stitch lengths of approx. 4 mm are
used for gathering or sewing on a elastic band. The stitch length can be infinitely adjusted between 0,8 – 4,5
mm while sewing.
> Tap on the stitch length icon on the sewing screen.
To enable a «blind operation», the setting range is displayed larger when the machine is running.
Optimizing the stitch lenght for cover stitches
The stitch lenght should be reduced in the smallest possible steps from the basic value.
A blue ribbon indicates that the set value is in the experimental range. In rare cases this may lead to
skipped stitches or problems with fabric feed occurs.
The stitch elasticity can also be increased by reducing the differential feed.
