Insert the bobbin case so that the projection
on the bobbin case aligns with the spring.
Insert the tabs on the needle plate cover
into the needle plate, and then slide the
cover back on.
• 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.
