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
ton.
NEEDLE-THREAD TENSION
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
ber.
• To increase tension, turn dial to higher num­
ber.
BOBBIN-THREAD TENSION

tension, refer to page 13.
