90% of your sewing will be done with the tension control dial (on top of the machine) set at “ 5 ” .
Helpful Hint: A slight adjustment to a higher number or a lower number may
improve sewing appearance.
ADJUSTING TOP THREAD TENSION
Under side
Top side
Well balanced
Top stitch too tight
Top stitch too loose
Increase tension
Decrease tension
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 nd 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 desirable 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.
