Note: *In general, fine threads and needles are used for sewing thin fabrics, and thicker threads and needles are

used for sewing heavy fabrics, Always test thread and needle size on a small piece of fabric which will

be used for actual sewing.

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.

Tighten the needle thread tension by

Remember the higher the number, the tighter the tension. Correctly balanced tensions 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. The general range for many fabrics is 3-5.
