Adjusting thread tension
When embroidering, the thread tension should be set so that
the upper thread can slightly be seen on the wrong side of the
fabric.
■ Correct thread tension
The pattern can be seen from the wrong side of the fabric.
If the thread tension is not set correctly, the pattern will
not finish well. The fabric may pucker or the thread may
break.

Making Embroidery Adjustments
Note
• If the thread tension setting is made extremely
weak, the machine may stop during sewing. This
is not the sign of a malfunction. Increase the
thread tension slightly, and begin sewing again.
Memo
• If you turn the main power to OFF or select a
different pattern, the thread tension will reset to
the automatic setting.
• When you retrieve a saved pattern, the thread
tension setting will be the same as when the
pattern was saved.
Note
• If the bobbin thread was incorrectly threaded,
the upper thread may be too tight. In this case,
refer to “Setting the Bobbin” of “Basic
operations” 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” of “Basic operations” and
rethread the upper thread.
