5.4 Adjusting the upper thread tension
The default setting of the upper thread tension is determined automatically after stitch pattern is selected.
The upper thread tension is set optimally at the BERNINA factory and the machine has been tested.
Metrosene-/Seralon thread size 100/2 (Company Mettler, Switzerland) is used for upper and bobbin thread.
When of using other types of sewing threads, the optimal upper thread tension may vary. Therefore it may
be necessary to adjust the upper thread tension individually according to the sewing project as well as the
desired stitch pattern.
The higher the upper thread tension, the tighter the upper thread which means that the bobbin thread is
pulled up to the top of the fabric. When the upper thread tension is low, the upper thread is less tightened
which means that the bobbin thread is pulled up less.
Alterations of the upper thread tension affect the currently selected stitch pattern. Permanent alterations of
the upper thread tension can be made in the Setup Program (see page 46).
Prerequisite:
•
In the Setup Program the upper thread tension has been altered.
