How do I wind the bobbin?

Wind the bobbin

Only use the bobbin that comes with this machine or bobbins of the same type (part code: SA156, SFB: XA5539-151). Using other bobbins may cause damage to the machine.
We designed the bobbin that comes with this machine. If you use bobbins from other models, the machine will not work properly.

(1) This model
(2) Other models
(3) 11.5 mm (7/16 inch)

Place the bobbin on the bobbin winder shaft so that the spring on the shaft fitsinto the notch of the bobbin.

(2) Spring on the shaft
Slide the bobbin winder shaft to the rightuntil it snaps into place.
Swing up the spool pin, and then remove the spool cap.

(1) Spool pin
(2) Spool cap
Fully insert the spool of thread for the bobbin onto the spool pin.

Slide the spool onto the pin so that the spool is horizontal and the thread unwinds to the front at the bottom.

If the spool is not positioned so that the thread unwinds correctly, the thread may become tangled around the spool pin.
Slide the spool cap onto the spool pin.
- With the slightly rounded side of the spool cap positioned toward the left,slide the spool cap onto the spool pin as far as possible to the right so that the spool is moved to the right end of the spool pin.
- When sewing with fine, cross-wound thread, use the small spool cap, and leave a small space between the cap and the spool.

  (2) Spool (cross-wound thread)
  (3) Space
While holding the spool with your right hand, pull the thread with your left hand, and then pass the thread under the thread guide A.

(1) Thread guide "A"
Pass the thread under the thread guide cover from the back to the front.

(1) Thread guide "B"

Hold the thread with your right hand so that there is no slack in the thread that is pulled out, and then pass the thread under the thread guide B with your left hand.
Pull the thread to the right, pass it under the hook of the bobbin-winding thread guide, and then wind the thread counterclockwise between the discs, pulling it in as far as possible.

(1) Hook of the bobbin-winding thread guide
(2) Pre-tension disk
While using your left hand to hold the thread that was passed through the bobbin-winding thread guide, use your right hand to wind the end of the thread clockwise around the bobbin five or six times.
Pass the end of the thread through the slit in the bobbin winder seat, and then pull the thread to the right to cut it.

(1) Slit in bobbin winder seat (with built-in cutter)

Be sure to cut the thread as described. If the bobbin is wound without cutting the thread using the cutter built into the slit in the bobbin winder seat, the bobbin may not be wound correctly. In addition, the thread may become tangled in the bobbin or the needle may bend or break when the bobbin thread starts to run out.
Turn on the machine.

Do not turn on the machine while pressing down the foot controller. The machine may start unexpectedly and cause personal injury or damage to the machine.
Press the foot controller to start.
When the bobbin seems full and begins spinning slowly, take your foot off the foot controller.

When the bobbin winding becomesslow, stop the machine, otherwise thesewing machine may be damaged.
Cut the thread, slide the bobbin winder shaft to the left, and then remove the bobbin from the shaft.
- 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 winder shaft to the right.
