CAUTION
• 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: XE5342-101 (green marking
on the screw), XC8167-551 (no color on the
screw), XE8298-001 (gray, for bobbin work)),
contact your nearest authorized Brother
dealer.
• Make sure that you fit the bobbin case
properly, otherwise the needle may break.
Note
• If the needle plate has been removed it is
especially important to reinstall the needle
plate and tighten the screws prior to
installing the bobbin case.
