Note
• 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: XC3153-051 (green screw),
XC8167-051 (pink screw)), contact your
nearest authorized service center.
• Be sure that the bobbin case is correctly
installed. Otherwise, the needle may break.
• If the needle plate has been removed it is
especially important to reinstall the needle
plate and tighten the screws prior to install-
ing the bobbin case.
