Singer 9940 Adjusting the Thread Tensions, When upper thread appears on the bottom side of fabric

Page 36

ADJUSTING THE THREAD TENSIONS

Normally, when upper thread regulating dial is set to [AUTO], thread tensions will be satisfactory for most all sewing.

If it is difficult to obtain correct tensions depending on the type of fabric and threads being used, adjust the upper thread tension dial to settings shown below.

A. Correct Thread Tensions Upper and bobbin threads should lock approximately in the middle of fabric.

B. When bobbin thread appears on top side of fabric

Turn the tension dial to the left (-).

C. When upper thread appears on the bottom side of fabric

Turn the tension dial to the right (+).

D. Thread Tension for Zigzag Stitches To sew zigzag stitches, the thread tension should be set to a slightly weaker tension than when sewing straight stitches.

You will obtain a nicer stitch when upper thread appears on bottom side of fabric.

Helpful Hint

If your sewing appears as shown on drawing, stitches on top side of fabric are good but bottom side tends to look like a towel, it could be that the upper thread is not threaded correctly (especially threading of the upper thread tension regulator may not be correct.) Refer to page 28 for correct threading.
