2 Wound poorly
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 (XA5539-151)).
Be sure to turn off the power. If you
accidentally step on the foot controller
and the machine begins to operate, injury
could result.
