Setting the thread tension
You may need to change the thread tension, depending on the
fabric and thread being used.
■ 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.
1 Wrong side of fabric
2 Right side of fabric
3 Upper thread
4 Bobbin thread
■ Upper thread is too tight
If the bobbin thread is visible from the right side of the
fabric, the upper thread is too tight.
Loosen the thread tension.
1 Wrong side of fabric
2 Right side of fabric
3 Upper thread
4 Bobbin thread
5 The bobbin thread is visible from the right side of the
fabric.
Pushing the thread tension dial toward the left makes the
thread tension looser.
■ Upper thread is too loose
If the upper thread is visible from the wrong side of the
fabric, the upper thread is too loose.
Tighten the thread tension.
1 Wrong side of fabric
2 Right side of fabric
3 Upper thread
4 Bobbin thread
5 The upper thread is visible from the wrong side of the
fabric.
Pushing the thread tension dial toward the right makes the
thread tension tighter.
Note
• If the bobbin thread was incorrectly threaded, the
upper thread may be too tight. In this case, refer
to “Installing the bobbin” on page B-16 and
rethread the bobbin thread.

Note
• If the upper thread was incorrectly threaded, the
upper thread may be too loose. In this case, refer
to “Upper Threading” on page B-19 and rethread
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.
