Adjusting the thread tension dials
Thread tension dial
Make sure that the threads are properly seated in the tension dials..
There is a thread tension dial for each needle thread, the lower looper thread and the upper looper thread. The correct thread tension may vary according to the type and thickness of the fabric and the type of thread used. Thread tension adjustments may be necessary for any change in sewing materials.
