Never use a bobbin case that is scratched,
otherwise the upper thread may become
tangled, the needle may break or sewing
performance may suffer. For a new bobbin
case (part code: XC3153-221 (green
marking), XC8167-451(
no color on the

service center.
● Be sure that the bobbin case is correctly
installed, otherwise the needle may break.
