THREAD TENSION DIAL TENSION
STANDARD
With the presser foot down and the thread tension dial set to position 4, when polyester thread (#60, green) is
pulled slowly down with the tension gauge, the reading should be 0.33-0.38 N (33-38 gf).
ADJUSTMENT
1. Set the thread tension dial position to position 4, put the polyester thread (#60, green) between the plate and
the plate, and lower the presser foot.
2. Loosen the screw securing the thread tension nut.
3. Pull the thread slowly with the tension gauge in the direction shown in the figure and adjust by turning the
thread tension adjustment screw so that the reading on the tension gauge is 0.33-0.38 N (33-38 g f).
4. Tighten the screw securing the thread tension nut.
Adjustment Point
3.
Adjust with the thread just passing the thread tension adjustment plates and not passing the upper thread
guide plate. For tension checking, use thread that is as new as possible. (If old thread is used, the
tension may not be measured accurately.)
