• Thread tension too loose for straight stitch sewing. Turn
dial to hiQher number (B).
• Thread tension too tight for straight stitch sewing. Turn
dial to lower number (C).
• Normal thread tension for zig zag and decorative sewing
(D).
Please note:
• Proper setting of tension is important to good sewing.
• There is no single tension setting appropriate for all stitch
functions, thread on fabric.
• A balanced tension (identical stitches both top and
bottom) is usually only desireable for straight stitch
construction sewing.
• 90% of all sewing will be between 3 and 5 (4 is basic
setting).
• 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.
