ADJUSTING TOP THREAD TENSION 90% of your sewing will be done with the word "AUTO" displayed on the tension control dial on top of the machine. Helpful Hint: A slight adjustment to the + or - side of AUTO will improve sewing appearance. STRAIGHT STITCHING The good looking appearance of your stitching is largely determined by the balanced tension of both top and bobbin threads. The tension is well balanced when these two threads 'lock' in the middle of layers of the fabric you are sewing. If, when you start to sew, you find that the stitching is irregular, you will need to adjust the tension control. Make any adjustments with presser foot 'down'. A balanced tension (identical stitches both top and bottom) is usually only desireable for straight stitch sewing. ZIG ZAG and DECORATIVE SEWING For zigzag sewing and decorative stitch functions, thread tension should be less than that for straight stitch sewing. You will always obtain a nicer stitch and less puckering when the upper thread appears slightly on the bottom side of your fabric. BOBBIN TENSION The bobbin tension has been correctly set at the factory, so you do not need to adjust it.
