GETTING READY TO SEW – 25
Dierential Feed Adjustment
The differential feed system consists of two sets of feed
teeth arranged one behind the other. Both feed teeth work in-
dependently of each other to give perfect results when sew-
ing on speciality fabrics. When the amount of feed by the
front feed teeth is changed in relation to the feed by the rear
feed teeth it will “stretch” or “gather” the fabric.
Use the dierential feed to prevent stretching of knit fabrics
and puckering of lightweight fabrics.
For overlock stitching on normal fabric, set the differen-
tial feed adjusting dial (A) to 1.0. The dierential feed dial
clicks when you turn the dial at 1.0.
If the sewn fabric stretches (B), turn the dial counterclock-
wise (toward 2.0).
If the sewn fabric is gathered (C), turn the dial clockwise
(toward 0.5).
Presser Foot Pressure Adjustment
The presser foot pressure for sewing based on normal condi-
tions should be set to “N” (A). Adjustments in some instanc-
es may be necessary. Increase or decrease the pressure until
you are satised with the result. Always test sew on a sample
of your fabric before sewing on your garment.
Decrease the pressure by turning the adjustment dial towards
you.
Increase the pressure by turning the adjustment dial away
from you.
Back to standard setting: Turn the adjustment dial until the
mark is set to ”N”.
