Adjusting Top Thread Tension; Bobbin Tension; Changing Presser Foot - Singer 398054 Operation And Safety Notes

ADJUSTING TOP THREAD TENSION

Most of your sewing will be done with the tension
control set at "4".
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 sew-
ing. 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
commonly desirable for straight stitch sewing.
ZIGZAG AND DECORATIVE SEWING
For zigzag sewing and decorative stitch func-
tions, 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.

CHANGING PRESSER FOOT

Be sure needle is in the up position. Raise
presser foot lifter.
1. Push presser foot release button to remo-
ve the foot.
2. Place the desired foot on the needle plate
aligning the presser foot pin with the foot
holder.
3. Lower the presser foot lifter so that the
foot holder snaps on the foot.
