ADJUSTING STITCH LENGTH
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
