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.
a
Follow steps from “CARE AND MAINTENANCE” in the operation manual to remove the
bobbin case.
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.
