Singer 20U - Threading the Bobbin Case

THREADING THE BOBBIN CASE
1. Hold bobbin so that thread unwinds in the direc-
tion shown, and put bobbin in bobbin case.
2. Pull thread into notch A and draw it under tension
spring B.
3. Draw thread out from slot on end of spring and
pass it through bobbin case thread guard C. Allow
about 4 inches of thread to hang freely from
bobbin.
NOTE: When straight stitching, a better result can
be obtained if bobbin-thread is not threaded through
bobbin case thread guard C.
