The differential feed system consists of two sets of feed
teeth arranged one behind the other. Both feed teeth work
independently of each other to give perfect results when
sewing on speciality fabrics. When the amount of feed by
the front feed teeth is changed in relation to the feed by

Use the differential feed to prevent stretching of knit
fabrics and puckering of lightweight fabrics.
The differential feed is automatically set to 1.0 when
any of the coverlock™ 4.0 stitches is selected. This is the
setting for overlock stitching on normal fabric. To adjust
the differential feed, touch the differential feed icon. It
becomes surrounded by a black frame, showing that it is
selected. Touch - or + to adjust the differential feed.
Gathered overlock (stretch, knit fabrics)
When overedging stretch fabric, such as knits and jersey, adjust the differential feed to a value between 1.0 and 2.0. The
setting depends on the material being sewn as well as the desired amount of gathering. Test sew with different settings
before sewing on your garment.
Stretch overlock (lightweight fabrics)
When overedging light woven or loosely knit fabrics, such as silk and silky knitwear, adjust the differential feed to a
value between 0.6 and 1.0. When sewing, apply gentle tension to the fabric by holding the seam lightly in front and
back of the presser foot. The setting depends on the material being sewn as well as the desired amount of stretching.
Test sew with different settings before sewing on your garment.
