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.
