Setting the Thread Tension

You may need to change the thread tension,
depending on the fabric and thread being used.
Follow the steps below to make any necessary
changes.

■ Proper 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.

■ Upper Thread is Too Tight

If the bobbin thread is visible on the right side of the
fabric, the upper thread is too tight.
Note
• If the bobbin thread was incorrectly
threaded, the upper thread may appear to
be too tight. In this case, refer to "Setting
the Bobbin" of "Basic operations" and
rethread the bobbin thread.
