Select a stitch.

CAUTION
After selecting a stitch, slowly turn the
G
handwheel toward you
(counterclockwise) and check that the
needle does not touch the presser foot. If
the needle hits the presser foot, the
needle may bend or break.
The twin needle should only be used
G
with the Straight Stitch (Center Needle
Position) and the Zigzag Stitch (1.5 mm
(1/16 inch) width). Do not use the twin
needle with any other stitches.
Start sewing.

For details on starting to sew, refer to "Starting
sewing" on page 23.
Two lines of stitching are sewn parallel to
each other.
CAUTION
When changing the sewing direction, be
G
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
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
G We recommend that you do a test sample
on scrap of a fabric before you start to sew.
I Correct tension
Correct tension is important as too much or too little
tension will weaken your seams or cause puckers
on your fabric.
