Cleaning the bobbin case

Thread wax and dust easily collect around the hole
in the tension-adjusting spring on the bobbin case,
resulting in an incorrect thread tension. Therefore,
it should be cleaned each time when the bobbin is
changed.
Use a piece of paper with the thickness of a
business card.
1 Open the hook cover, remove the bobbin
case, and then remove the bobbin. (Refer to
page 36.)
2 Slide the paper under the tension-adjusting
spring to remove any dust.
Use a corner of the paper to remove any dust
from around the hole.
1 Tension-adjusting spring
2 Hole
3 Paper
