How do I install the bobbin wound with thread?
-
Winding the bobbin improperly may causethe thread tension to loosen, breaking the needle and resulting in injury.
-
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).

-
Put the bobbin in so the thread comes out in the direction shown by the arrow.
Make sure you set the bobbin so the thread 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.
-
Hold the end of the thread, push the bobbin down with your finger, and then pass the thread through the slit, as shown.
(1) Tension-adjusting spring
If the thread is not correctly inserted through the tension-adjusting spring of the bobbin case, it may cause incorrect thread tension.
-
Replace the bobbin cover.
Put the left tab in place (see arrow A), and then press lightly on the right side (see arrow B) until the cover clicks into place.
Replace the cover so that the end of the thread comes out from the left side of the cover (as shown by the line in the diagram).
