UPPER THREAD TENSION DIAL
Correct setting
The upper thread tension should be 65 - 95g when pulling the thread (cotton thread Size
50) in the direction of B with setting the tension dial at “3”.
(Make sure the foot is lowered.)
If the tension is out of the standard range, adjust it as follows:
To adjust
1. Remove the front panel cover unit. (See page 4.)
2. Turn the adjusting nut C in the direction of D when the upper thread tension is too
tight.
Turn the adjusting nut C in the direction of E when the upper thread tension is too
loose.
3. Attach the front panel cover unit.
