GETTING READY TO SEW – 25
Differential Feed Adjustment
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
the rear feed teeth it will “stretch” or “gather” the fabric.
Use the differential feed to prevent stretching of knit fab-
rics and puckering of lightweight fabrics.
For overlock stitching on normal fabric, set the differen-
tial feed adjusting dial (A) to 1.0. The differential 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
conditions should be set to “N” (A). Adjustments in some
instances may be necessary. Increase or decrease the pres-
sure until you are satisfied with the result. Always test
sew on a sample of your fabric before sewing on your gar-
ment.
Decrease the pressure by turning the adjustment dial to-
wards 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”.
