Adjusting Top Thread Tension; Top Thread, Bobbin Tension; Changing Presser Foot - Singer 8763 CURVY Manual

ADJUSTING TOP THREAD TENSION

90% of your sewing will be accomplished with the word "AUTO"
exposed on the tension control dial on top of the machine.
Helpful Hint: A slight adjustment to a higher number or a
lower number may improve sewing appearance.
STRAIGHT STITCHING
The correct appearance of your stitching is largely determined
by the balanced tension of both top and bobbin threads. The
tension is well balanced when these two threads 'lock' in the
middle of layers of the fabric you are sewing.
If, when you start to sew, you find that the stitching is irregular,
you will need to adjust the tension control.
Make all adjustments with presser foot 'down'.
A balanced tension (identical stitches both top and bottom) is
usually only desireable for straight stitch sewing.
ZIG ZAG and DECORATIVE SEWING
For zigzag sewing and decorative stitch functions, thread
tension should be less than for straight stitch sewing.
You will always obtain a nicer stitch and less puckering when
the upper thread appears slightly on the bottom side of your
fabric.
BOBBIN TENSION
The bobbin tension has been correctly set at the factory,
so you do not need to adjust it.
