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 from the right side of
the fabric, the upper thread is too tight.

• If the bobbin thread was incorrectly
threaded, the upper thread may be too
tight. In this case, refer to “Setting the
Bobbin” on page 58 and rethread the
bobbin thread.
• When you finish sewing, remove the bobbin
cover and then make sure that the thread is
shown as below. If the thread is not shown
as below, the thread is not inserted through
the tension-adjusting spring of the bobbin
case correctly. Reinsert the thread
correctly. For details, refer to page 58.
• If the upper thread was incorrectly
threaded, the upper thread may be too
loose. In this case, refer to “Upper
Threading” on page 61 and rethread the
upper thread.
• Press to return the thread tension
to the original setting.
