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.
