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.
