SEWING
7Start sewing.
For details on starting to sew, refer to “Starting sewing” on page 25.
XTwo lines of stitching are sewn parallel to
each other.
Note
●When using the twin needle, the stitches may become bunched together, depending on the types of thread and fabric that are used. If this occurs, increase the stitch length. For details on adjusting the stitch length, refer to “Stitch length dial” on page 12.
CAUTION
●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.
Thread tension
■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 16 and rethread the bobbin thread.

■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 18 and rethread the upper thread.
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. |
