Differential Feed Adjustment

The differential feed system consists of two sets of feed teeth

arranged one behind the other. Both feed teeth work inde-

pendently 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 fabrics

and puckering of lightweight fabrics.
For overlock stitching on normal fabric, set the differential

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 counterclockwise

(toward 2.0).
If the sewn fabric is gathered (C), turn the dial clockwise (to

-

ward 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 instances

may be necessary. Increase or decrease the pressure until you

are satisfied 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”.
