    • 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, contact your nearest Brother authorized service center.
    • Be sure that the bobbin case is correctly installed, otherwise the needle may break.
