Lower thread tension (1)
Upper thread tension
Note:
To test the bobbin thread tension, remove the bobbin case and
bobbin and hold it by suspending it by the thread. Jerk it once or
twice. If the tension is correct, the thread will unwind by about
an inch or two.
If the tension is too tight, it does not unwind at all. If the tension
is too loose, it will drop too much. To adjust, turn the small
screw on the side of the bobbin case.
Basic thread tension setting: "4"
To increase the tension, turn the dial to the next number up.
To reduce the tension, turn the dial to the next number down.
