wound without cutting the thread using the cutter built
into the slit in the bobbin winder seat, the thread may
become tangled in the bobbin or the needle may bend
or break when the bobbin thread starts to run out.
CAUTION
● Not winding the bobbin properly may cause the
thread tension to loosen, and may break the needle.
