yourtop threadtension,tt consistsof 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 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 is best to test the stitching on a scrap of the fabric you are using before

starting to make a garment._ To adjust for the correct stitch, see next pager

(_ Upper thread too tight

A perfect straight stitch wil! have threads locked between the two

layers of fabric with no loops on

top or bottom.

Decrease Tension

(_ Upper thread too loose

Increase Tension

{: .... •

Bobbin tension requires adjusting tess 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 as indicated on Page 9

When adjusting the tension on the bobbin case, make slight adjustments with

a screwdriver

The easiest way to check tensions is to sew a medium zig zag stitch on the fabric you will be using, Use the appropriate type of thread and needle

Use different colors of thread on the bobbin and upper spool

Sew a line of zig zag stitches The bobbin thread should not show on the top of the fabric

Adjust the top tension if necessary to achieve the stitch balance mentioned above
