The stitch length dial controls the length of

stitches. The numbers around the edge of. the
dial express stitch length in mm; the lower the
number, the shorter the stitch. Generally, shorter

stitches are best for lightweight fabric, longer
stitches for heavy fabric. The area from 0 to 1
is used for the adjustment of zig-zag satin
stitching (see page 22).

Setting the Dial

• Turn dial so that stitch length desired is posi­

tioned under ^ symbol.

• To shorten stitch length, turn dial to the left

toward a lower number.

• To lengthen stitch length, turn dial to the

right toward a higher number.

For reverse stitching, depress push button lo­

cated in centre of dial, hold in until reverse

stitching is completed, then release push but­


Note: Reverse stitching cannot be done when

using a stretch stitch pattern.


Correct tension is important because too much
or too little will weaken your seams or cause
your fabric to pucker. Make a test sample with
the fabric and the thread you plan to use and
examine it. A well balanced stitch, as shown in

illustration A, will have the needle and bobbin

threads locked between the two layers of fabric
with no loops on top or bottom and no pucker.
The tension dial regulates the degree of ten­

sion on your needle thread. Set it according to
the type of thread and fabric you use. The num­

bers on the dial eliminate guesswork.

If the fabric puckers B, decrease tension. If the

stitches in your test sample look loose C, in­
crease needle-thread tension.

• To decrease tension, turn dial to lower num­


• To increase tension, turn dial to higher num­
