Adjusting Presser Foot Tension

The amount of downward pressure put on the application by the presser foot is
controlled by the presser regulating thumbscrew (A). This screw compresses a
long coil spring above the presser foot.
For sewing heavy, hard-to-feed materials, it is best to have very high pressure
on the foot for optimum feeding. For these materials, tighten the screw until only
1/2 inch or less of the screw's threads are showing (40).
When sewing delicate or spongy materials, reduce the foot pressure. Turn the
thumbscrew until it comes free of the machine, and then rethread it about three
complete rotations for the lightest spring setting (41).
