Cleaning the Bobbin Case
Thread wax and dust easily collect around the notch in the
tension spring on the bobbin case, resulting in an incorrect
thread tension. Therefore, the bobbin case should be cleaned
as necessary should tension problems arise.
When cleaning the bobbin case, use card stock or another
type of paper of similar thickness and sturdiness in order to
prevent pieces of paper tearing off and getting lodged in the
bobbin case.
