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 “Installing 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.
