ADJUSTING TOP TENSIONS
Probably the most important control on your machine is this one that regulates your
top thread tension. It consists of discs between which the thread passes. The
pressure on these discs is regulated by turning the dial. The higher the number, the
tighter the tension.
There are many reasons for having to reset your tension. The best tension for one
fabric may not be correct for another. The required tension depends upon the
stiffness of the fabric, thickness of the fabric, numbers of layers of fabric being
sewn, as well as the type of stitch you are making.
it isbest to test the stitching on a scrap of the fabric you are using before starting to
make a garment as shown below. Use the straight stitch function.
