Top tension control
Probably the most important control on your machine is the 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 on the front of the control. The higher the number, the tighter the tension.
There are many reasons for having to reset your attention. 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, number of layers of fabric being sewn, as well as type of stitch you are making.
It is best to test the stitching on a scrap of fabric you are using before starting to make a garment.
A perfect stitch will have the threads locked between the two layers of fabric with no loops on the top or bottom
If loops appear on top of fabric, upper tension is too tight. Decrease tension knob dial.
If loops appear on the bottom of fabric, tension is too loose. Increase tension knob dial.
Bobbin tension requires adjusting less frequently than the upper thread tension.
If the Stitch is satisfactory but the seam is puckered, it may be necessary to loosen the tension on both the top and bottom threads. Be sure to balance them evenly.
Adjusting bobbin tension
When adjusting the tension on the bobbin case. Make slight adjustments with a screwdriver.
