Adjusting the Thread Tension

The following procedure describes how to adjust the thread tension if the correct thread tension as described on page 45 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.
