Start sewing.
For details on starting to sew, refer to “Starting
sewing” on page 18.
X Two lines of stitching are sewn parallel to
each other.
CAUTION
Thread tension
The tension of the thread will affect the quality of your
stitches. You may need to adjust it when you change
fabric or thread.
Memo
● We recommend that you do a test sample
on scrap of a fabric before you start to sew.
■ Correct tension
Correct tension is important as too much or too little
tension will weaken your seams or cause puckers
on your fabric.
■ Upper tension is too tight
Loops will appear on the surface of the fabric.
Note
● If the bobbin thread was incorrectly
threaded, the upper thread may be too tight.
In this case, refer to “Lower threading” on
page 13 and rethread the bobbin thread.
Solution
Reduce the tension by turning the upper tension
control dial to a lower number.
■ Upper tension is too loose
Loops appear on the back of the fabric.
Note
● If the upper thread was incorrectly threaded,
the upper thread may be too loose. In this
case, refer to “Upper threading” on page 14
and rethread the upper thread.
Solution
Increase the tension by turning the upper tension
control dial to a higher number.
● When changing the sewing direction, be
sure to raise the needle from the fabric,
and then raise the presser foot lever and
turn the fabric. Otherwise the needle
may break or the machine may be
damaged.
