Lower thread tension

The standard tension of the lower thread is

0.15~ 0.3N.

This tension may vary depending on the used

thread. In general, press the bobbin case to a

smooth vertical surface and hang the

designated number of coins. Turn the thread

tension screw so that the lower thread will come

out smoothly.

Note) Check that the bobbin is pushed out of the

bobbin case by about 0.5 mm. If not, the slip

prevention spring of the bobbin case does not

work. Adjust the spring in height or replace it

with a new one. (Refer to “Replacing Bob-

bin” on page 39.)
