c Pull it in as far as possible.
→ Check to make sure thread is securely set between 
pre-tension disks.
 CAUTION
 If the thread spool and/or spool cap are set 
incorrectly, the thread may tangle on the spool 
pin and cause the needle to break.
 Use the spool cap (large, medium, or small)  that is closest in size to the thread spool. If a 
spool cap smaller than the thread spool is 
used, the thread may become caught in the slit 
on the end of the spool and cause the needle 
to break.
Memo
 When sewing with fine, cross-wound thread, use the small spool cap, and leave a small 
space between the cap and the thread 
spool.

jPress .
→Bobbin winding starts automatically. The bobbin 
stops rotating when bobbin winding is completed. 
The bobbin winding switch will automatically return 
to its original position.
 CAUTION
 Be sure to follow the process described. If the 
thread is not cut with the cutter, and the 
bobbin is wound, when the thread runs low it 
may tangle around the bobbin and cause the 
needle to break.
Memo
 Sliding the bobbin winding switch to the left switches the machine into bobbin winding 
mode.
Note
  changes to   while the bobbin 
is winding.
 Stay near the machine while winding the  bobbin to make sure the bobbin thread is 
being wound correctly. If the bobbin thread 
is wound incorrectly, press   immedi-
ately to stop the bobbin winding.
 The sound of winding the bobbin with stiff  thread, such as nylon thread for quilting, 
may be different from the one produced 
when winding normal thread; however, this 
is not a sign of a malfunction.
Memo
 You can change the winding speed by 
pressing   (to decrease) or   (to 
increase) in the bobbin winding window.
 Press   to minimize the bobbin winding  window. Then, you can perform other 
operations, such as selecting a stitch or 
adjusting the thread tension, while the 
bobbin is being wound.
 Press   (in top right of the LCD screen)  to display the bobbin winding window again.

■Using the Spool Pin
You can use the main spool pin to wind the bobbin 
before sewing. You cannot use this spool pin to 
wind the bobbin while sewing.
aTurn the main power to ON and open the 
top cover.
bAlign the groove in the bobbin with the 
spring on the bobbin winder shaft, and set 
the bobbin on the shaft.

Memo
 When removing the bobbin, do not pull on 
the bobbin winder seat. Doing so could 
loosen or remove the bobbin winder seat, 
and could result in damage to the machine.
 CAUTION
 Setting the bobbin improperly may cause the 
thread tension to loosen, breaking the needle 
and possibly resulting in injury.

■ Using the Spool Stand
To wind thread on the bobbin while the spool stand 
is installed, pass the thread from the spool through 
the thread guide on the telescopic thread guide, and 
then wind the bobbin according to steps 
e through 
k of “Using the Supplemental Spool Pin”on 
page 49 to page 51.
Memo
 See page 21 to assemble the spool stand.
 See page 63 to thread the machine using  the spool stand.
 CAUTION
 When winding thread on the bobbin, do not 
cross the bobbin winding thread with the 
upper thread in the thread guides.

■Untangling Thread from Beneath the 
Bobbin Winder Seat
If the bobbin winding starts when the thread is not 
passed through the pre-tension disk correctly, the 
thread may become tangled beneath the bobbin 
winder seat.
Wind off the thread according to the following 
procedure.
a Thread
b Bobbin winder seat
aIf the thread becomes tangled under the 
bobbin winder seat, press   once to 
stop the bobbin winding.
bCut the thread with scissors near the pre-
tension disk.
aPre-tension disk
cPush the bobbin winder switch to the right, 
and then raise the bobbin at least 10 cm 
(4 inches) from the shaft.
dCut the thread near the bobbin and hold the 
thread end with your left hand. Unwind the 
thread clockwise near the bobbin winder 
seat with your right hand as shown below.
eWind the bobbin again.
 CAUTION
 Do not remove the bobbin winder seat even if 
the thread becomes tangled under the bobbin 
winder seat. It may result in injuries.
Note
 Make sure that the thread passes through the pre-tension disk correctly (page 49).

the thread unwinds to the left.
fHold the bobbin lightly with your right 
hand, and then guide the thread with your 
left hand.
 CAUTION
 Use a bobbin thread that has been correctly 
wound. Otherwise, the needle may break or 
the thread tension will be incorrect.
 The included bobbin was designed specifically  for this sewing machine. If bobbins from other 
models are used, the machine will not operate 
correctly. Use only the included bobbin or 
bobbins of the same type (part code: SA156, 
(SFB: XA5539-151)).

sure to press   in the LCD, otherwise 
injuries may occur if the “Start/Stop” button 
or any other button is pressed and the 
machine starts sewing.

example, when making gathers, darts, or doing 
free motion quilting or embroidery.
aGuide the bobbin thread through the 
groove, following the arrow in the 
illustration.
* Do not cut the thread with the cutter.
* Do not replace the bobbin cover.

eGently pull the upper thread. A loop of the 
bobbin thread will come out of the hole in 
the needle plate.
Note
 If the thread is not correctly inserted through 
the tension spring of the bobbin case, it may 
cause incorrect thread tension. (see page 
79)

 CAUTION
 Be sure to hold down the bobbin with your 
finger and unwind the bobbin thread 
correctly. Otherwise, the thread may break or 
the thread tension will be incorrect.

 CAUTION
 Be sure to thread the machine properly. 
Improper threading can cause the thread to 
tangle and break the needle, leading to injury.
 When using the walking foot, the side cutter or  accessories not included with this machine, 
attach the accessory to the machine after 
threading the machine.
Memo
 The automatic threading function can be used with sewing machine needle sizes 75/
11 through 100/16.
 Thread such as transparent nylon monofila- ment thread and thread with a thickness of 
130/20 or thicker cannot be used with the 
automatic threading function. 
 The automatic threading function cannot be  used with the wing needle or the twin nee-
dle.
Memo
 This machine is equipped with an upper 
thread shutter, allowing you to check that 
the upper threading is performed correctly.
Note
 If you try to thread the needle automatically without raising the needle, the thread may 
not thread correctly.

pin and cause the needle to break.
 Use the spool cap (large, medium, or small)  that is closest in size to the thread spool. If a 
spool cap smaller than the thread spool is 
used, the thread may become caught in the slit 
on the end of the spool and cause the needle 
to break.
Memo
 When sewing with fine, cross-wound thread, use the small spool cap, and leave a small 
space between the cap and the thread 
spool.
