Memo
● When the sewing machine is started or the
handwheel is turned after winding the
thread around the bobbin, the machine will
make a clicking sound; this is not a
malfunction.
● The needle bar does not move when you
slide the bobbin winding shaft to the right.
Lower threading
Install the bobbin wound with thread.
• For more details on quick-set bobbin, see page 15.

the handwheel toward you (counterclockwise) or

c
Put the bobbin in so the thread comes out in
the direction shown by the arrow.
• Only use bobbins that were designed to be
used with this machine.
d
Hold the end of the thread, push the bobbin
down with your finger, and then pass the
thread through the slit, as shown.
• If the thread is not correctly inserted through
the tension-adjusting spring of the bobbin
case, it may cause incorrect thread tension
(page 29).
a Tension-adjusting spring
● Winding the bobbin improperly may cause the
thread tension to loosen, breaking the needle
and resulting in injury.
a Wound evenly
b Wound poorly
● The bobbin was designed specifically for this
sewing machine. If bobbins from other models
are used, the machine will not operate
correctly. Use only the enclosed bobbin or
bobbins of the same type (part code: SA156,
SFB: XA5539-151).
● Make sure you turn the power off while
threading the machine. If you accidentally
step on the foot controller and the machine
starts to sew, you could be injured.

unrolls in the right direction. If the thread unrolls
in the wrong direction, it may cause the thread
tension to be incorrect or break the needle.
