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.
