from front to back.
CAUTION
d
Raise the presser foot lever, pass the end of the
thread through the presser foot, and then pull
out about 5 cm (2 inches) of thread toward the
rear of the machine.
Using the twin needle
With the twin needle, you can sew two parallel lines
of the same stitch with two different threads. Both
upper threads should have the same thickness and
quality. Be sure to use the twin needle, the extra
spool pin and the spool cap.
For details on the stitches that can be sewn with the
twin needle, refer to “Stitch Settings” (page 138).
CAUTION
a
Install the twin needle.
• For details on installing a needle, refer to
“Replacing the needle” (page 39).
b
Thread the upper thread for the left needle
eye.
• For details, refer to steps
a
through
l
of
“Threading the upper thread” (page 28).
c
Manually thread the left needle with the upper
thread.
Pass the thread through the eye of the needle
from the front.
• The needle threader cannot be used with the
twin needle. If the needle threader is used
with the twin needle, the sewing machine
may be damaged.
● Do not touch the
(“Start/Stop” button),
(“Needle Position” button) or
(“Reverse/Reinforcement Stitch”
button). If one of the buttons is accidentally
pressed, the machine will begin sewing and
your finger may be pricked with the needle
or the needle may break.

● Only use the twin needle (part code:
X59296-151). Use of any other needle
may bend the needle or damage the
machine.
● Never use bent needles. Bent needles can
easily break, possibly resulting in injuries.
