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.
STRAIGHT STITCHING
The good looking 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 any 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 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.
