B. Thread tension too loose for straight stitch sewing. Turn dial to higher number.

C. Thread tension too tight for straight stitch sewing. Turn dial to lower number.

D. Normal thread tension for zig zag and decorative sewing. Correct thread tension is when a small amount of the upper thread appears on the bottom side of fabric.

Lower thread tension

The bobbin tension has been set correctly at the factory, so you do not need to adjust it.

Please note:

-Proper tension setting is important for strong seams.

-There is no single tension setting appropriate for all stitch functions, thread or fabric.

-A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing.

-90% of all sewing will be between "3" and "5".

-For zig zag and decorative sewing stitch functions, thread tension should generally be less than for straight stitch sewing.

-For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric.
