How do I clean the race?

If dust or bits of dirt collect in the race or bobbin case, the machine will not run well, and the bobbin thread detection function may not operate. Keep the machine clean for best results.
 

Unplug the power cord before cleaning the machine, otherwise injuries or an electric shock may occur.

    • 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.
