Adjusting the thread tension

The tensions of the upper thread and of the bobbin
thread (thread tension) should be adjusted so that
they are equal.
If the preset thread tension does not give the desired
result or if you are sewing with special thread or on
special fabric, use the thread tension dial to increase
or decrease the tension of the upper thread.
Note
● If the upper thread is not threaded correctly
or the bobbin is not installed correctly, it
may not be possible to set the correct thread
tension. If the correct thread tension cannot
be achieved, rethread the upper thread and
insert the bobbin correctly.
Memo
● We recommend that you do a test sample
on scrap of a fabric before you start to sew.

■ Correct thread tension
The upper thread and the bobbin thread should cross near
the center of the fabric. Only the upper thread should be
visible from the right side of the fabric, and only the bobbin
thread should be visible from the wrong side of the fabric.
