Tension is too tight

If the needle thread tension is too tight, the bobbin thread shows on the right side of the fabric. Reduce the tension by turning the tension dial to a lower number.

eBobbin thread

Tension is too loose

If the needle thread tension is too loose, the needle thread forms loops and the stitches look shaggy. Tighten the tension by turning the tension dial to a higher number.

Adjusting the bobbin thread tension

To tighten the bobbin thread tension, turn the adjusting screw clockwise.

To loosen the bobbin thread tension, turn the adjusting screw counterclockwise.

After the adjustment, test the tension by jerking the bobbin case with the thread end held by hand. The bobbin case should be falling slowly.

NOTE:

When adjusting the tension, turn the adjusting screw slightly since the adjustment is sensitive.
