Balancing needle thread tension:

- The needletop thread and the bobbin thread should interlock in the
center of two layers of fabric in straight seams.
- Set the desired number of the thread tension dial at setting mark.
- Tighten the needle thread tension by moving the dial to a higher
number.
- Loosen the needle thread tension by moving the dial to a lower num-
ber.
- NOTE: In order to obtain better zigzag stitches, the upper thread
tension should be slightly weaker than the bobbin thread tension. That
means, the upper thread should appear slightly on the reverse side of
the fabric, but the bobbin thread cannot appear on the top side of the
fabric.
