REGULATING THE THREAD TENSION
Generally, should any tension adjustment be necessary, the adjustment can normally be made by regulating the upper
thread tension dial only. Bobbin thread tension has been adjusted at the factory and readjustment is seldom required except
for special instances, thread and fabric.
Bobbin thread tension is just right when you can pull the thread from bobbin case easily with a little resistance.
Thread tension may be adjusted by tightening or loosening the thread tension dial.
The needle thread and the bobbin thread
Should interlock in the center of two layers of fabric.

Remember the higher the number, the tighter the tension. Correctly balanced tension for one fabric may not be suitable for
another. The required tension depends upon the stiffness of fabric, thickness of the fabric, numbers of layers of fabric being
sewn, as well as the type of stitch you are making. It is better to test the stitching on a scrap of the fabric you are using
before starting to make a garment.
