IDIUSTING UPPER THREAD TENSION

The correct stitch can usually be obtained by varying the upper thread tension

NOTE : TENSION ADJUSTMENT SHOULD BE MADE WITH THE

PRESSER FOOT DOWN.

To increase the tension, turn the tension dial clockwise (Fig. 20). To decrease

the tension, turn the tension dial counter clockwise (Fig. 20). When the tension

is properly adjusted, the upper and lower threads will cross in the center of
the material (Fig. 21-A).

When the upper thread tension is too tight, or the bobbin tension is too loose,
the lower thread will lay flat along the top of the material (Fig. 21-B).

When the upper thread tension is too loose or the bobbin tension too tiglii, the
upper thread will lay flat along the bottom of the material (Fig. 21-C).

The tension should be adjusted little by little until the desired tension is obtained.
