■ Upper tension is too loose
Loops appear on the wrong side of the fabric.
Note
● If the upper thread was incorrectly
threaded, the upper thread may be too
loose. In this case, refer to “Upper
threading” (page 16) and rethread.
Solution
Increase the tension by
turning the upper tension-
control dial to a higher
number.
■ Bobbin tension is too loose
Loops may appear on the surface of the fabric
when sewing thin fabric with thin thread.
Solution
Reduce the tension by
turning the upper tension-
control dial to a lower
number.
If the problem persists, increase the tension in
the bobbin by turning the screw clockwise
with a small screwdriver.
Be sure not to turn the screw more than one
full turn. In addition, be sure to return the
screw to its original position before the next
time that the machine is used.
Note
● The bobbin thread tension has been
adjusted at the factory for general use. For
most sewing applications, no adjustment is
needed.
