the designated number of coins. Turn the
thread tension screw so that the lower thread
will come out smoothly.

the bobbin case by about 0.5 mm. I

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 2-14)
2. For adjusting the height, loosen the screw [1] and turn the tension spring bracket [2].
3. For adjusting the tension spring force, insert a driver tip in the groove of the thread tension bar [3]
and turn it.
