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 (

Removing Material From
Under the Presser Foot
1�
Stop the machine after the take-up arm
(
B
) reaches its uppermost position
and then starts to descend�
2�
Raise the feet with the lift lever (

)�
3�
Remove the material from under the foot (

It may be helpful to rock the balance wheel
forward and back to free the thread�
4�
Cut the two threads to free the
material, leaving at least an 8-inch length
of thread coming out of the machine�
More than two threads? See p� 42�
