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 business 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.

of "Cleaning the race" (page 162).
b Using a piece of paper of adequate thickness
and sturdiness, slide the paper between the
tension plate base and the tension spring and
also slide the paper behind the notch of the
spring to remove any dirt or dust.
