Brother support says accumulated lint around the bobbin case and race can impair sewing performance. Its steps apply to specified home sewing models; other mechanisms differ. Follow your own manual when removing needles, screws or covers and use a service center if unsure.

Stop sewing, raise the needle, switch off and unplug the machine before touching the needle area.
Consult the model manual for removal of presser foot, needle and needle-plate cover; keep any small screws safe.
If your model allows it, carefully remove the bobbin case and note its alignment marks and orientation.
Use the supplied small cleaning brush to lift lint from the race and surrounding area. Brother does not recommend canned compressed air for the referenced procedure.
Do not oil the bobbin case without manufacturer approval. If it is scratched or distorted, stop and ask about the correct replacement.
Align the case marks, securely refit the cover and screws, and only then reconnect power and perform a cautious test stitch.
