BOBBIN THREAD TENSION
CORRECT SETTING
Set the bobbin in the bobbin case and pass the thread (cotton size 50) through the tension
spring. The bobbin thread tension should be 45 - 55g when pulling the thread in the
direction of B. If the tension is out of the range, adjust it as follows:
To adjust
1. Turn the adjusting screw “C” in the direction of “D” when the bobbin thread tension is
too tight.
2. Turn the adjusting screw “C” in the direction of “E” when the bobbin thread tension is
too loose.
