To sew a seam, apply gentle tension to the fabric by holding
the seam lightly in front and back of the presser foot.
Note: If amount of "stretch" is not correctly set in relation to the
fabric being sewn, the fabric is apt to shift away from the
needle resulting in improperly sewn overedge seam. In
such case, reset differential feed adjusting dial closer to
the center mark, or adjust width dial slightly to a larger
number.
*Be sure to reset the differential feed adjusting dial to “N" for
normal overedge stitching.
Stretch overedge is ideal for sewing decorative collars, sleeves,
skirt hems, etc. on loosely knit and woven fabrics.
Set differential feed adjusting dial below setting "N".
