Stretch overedge is ideal for sewing decorative
collars, sleeves, skirt hems, etc. on loosely knit and
woven fabrics.
Set differential feed adjusting lever knob above
setting "N".
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.
*Be sure to reset the differential feed
adjusting dial to graduation "N" for
normal overedge stitching.
