! ! ! ! Lower thread tension
W1251Q W1252Q
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.
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 Bobbin” on page 2-19.)
