Winding the Bobbin

This section describes how to wind thread onto a bobbin. With this machine, you can use the supplemental spool pin to wind the bobbin while sewing using the main spool pin.

CAUTION

•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: XA5539-051).

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.
