Adjusting the Thread Tension
The following procedure describes how to adjust the thread tension if the correct thread tension as described
on page 67 was not used. After adjusting the tension of the bobbin thread, adjust the tension of the upper
thread for each needle bar.
Note
●
Be sure to check the tension of the bobbin thread each time that the bobbin is changed.
Depending on the bobbin thread type and whether a prewound bobbin is used, the tension of the
bobbin thread may differ. For example, when replacing an empty prewound bobbin with one of the
same type, be sure to check the tension of the bobbin thread and adjust the tension if necessary.
●
Be sure to adjust the tension of the bobbin thread before adjusting the tension of the upper thread.

Different weights are used to adjust pre-
wound bobbins and metal bobbins.
Pre-wound bobbins: Only weight (L)
Metal bobbins: Weight (L) and weight (S)
* Weight (S) is included with the optional
bobbin winder.

If necessary, refer to page 249 for
reassembling the tension unit.

slowly pulled out, the thread tension is
correct.
