-
Only use bobbins (part code: SA156, SFB) that have been designed for this sewing machine.
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.
Only use the bobbin that comes with this machine or bobbins of the same type (part code: SA156, SFB).

As shown, press down on the spool pin lever with your finger.
The spool pin swings up.
Do not grab the bar to raise the spool pin, otherwise, the spool pin may bend or break.
-
Remove the spool cap.

Be sure to raise the spool pin when winding the bobbin.
The thread may become tangled if the bobbin winder is used without raising the spool pin. -
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.
-
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.
- If the spool or the spool cap is not positioned correctly, the thread may become tangled around the spool pin or the machine may be damaged.
-
Three spool cap sizes are available, allowing you to choose a spool cap that best fits the size of spool being used.
If the spool cap is too small for the spool being used, the thread may catch on the slit in the spool or the machine may be damaged.
When sewing with fine, cross-wound thread, use the small spool cap, and leave a small space between the cap and the spool.

While holding the spool with your right hand, and then pass the thread under the thread guide.
(1) Thread guide
-
Pass the thread under the thread guide cover from the back to the front.
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 cover 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.

Make sure that the thread passes under the pretension disk.

(3) Pretension disk
(4) Pull it in as far as possible.
Make sure that the thread is pulled as far as possible into the pretension disk, otherwise the bobbin may not be wound cleanly.
-
Put the bobbin onto the bobbin winder shaft and slide the bobbin winder shaft to the right.
Turn the bobbin clockwise, by hand, until the spring on the shaft slides into the notch in the bobbin.
Make sure to pull out 7 to 10 cm (2-3/4 to 3-15/16 inches) of thread from the hole on the bobbin.

(3) 7-10 cm (2-3/4 – 3-15/16 inches)
Pull the thread taut and hold the end of the thread straight up. If the thread is too short, not pulled taut or held at an angle, injuries may occur when the thread is wound around the bobbin.
-
Turn on the sewing machine.
-
While holding the end of the thread, gently press the foot controller to wind the thread around the bobbin a few times.
Then stop the machine.
-
Trim the excess thread above the bobbin.
Make sure you follow the instructions carefully. If you do not cut the thread completely, and the bobbin is wound, when the thread runs low it may tangle around the bobbin and cause the needle to break. -
Press the foot controller.
-
When the bobbin seems full and begins spinning slowly, take your foot off the foot controller.
-
Cut the thread, slide the bobbin winder shaft to the left and remove the bobbin.
- 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.
Not winding the bobbin properly may cause the thread tension to loosen, and may break the needle.
