CHANGING PRESSER FOOT

Be sure the needle is in the highest position. Raise presser
foot lifter.

1. Push presser foot release button to remove 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.

ADJUSTING TOP THREAD TENSION

90% of your sewing will be accomplished with the word “S”
exposed on the tension control dial on top of the machine.

STRAIGHT STITCHING

The correct appearance of your stitching is largely determined
by the balanced tension of both top and bobbin threads. The

middle of layers of the fabric you are sewing.

you will need to adjust the tension control. Do this, however,
only after you have determined that the machine is correctly
threaded (see page 7).

A balanced tension (identical stitches both top and bottom) is
usually only desirable for straight stitch sewing.

ZIGZAG, SATIN STITCH, DECORATIVE and
BUTTON HOLE SEWING

For zigzag sewing, satin stitch and decorative stitch functions,
thread tension should be less than that for straight stitch
sewing.

It is recommended for buttonholes to set thread tension at E.

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.

Helpful Hint: A slight adjustment to a higher number or a
lower number may improve sewing appearance.
