Adjusting the upper thread tension

The basic setting of the upper thread tension is provided automatically as soon as a stitch pattern is selected.
The upper thread tension is set optimally at the BERNINA factory and the sewing computer has been tested.
Metrosene-/Seralon thread size 100/2 (Company Mettler, Switzerland) is used for upper and bobbin thread.
In case of using other types of sewing threads, the optimal tension may vary. Therefore it may be necessary
to adjust the upper thread tension according to the sewing project as well as the desired stitch pattern
individually.
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.
Alteration of the upper thread tension affect the currently selected stitch pattern. Permanent alterations of
the upper thread tension for the sewing mode can be made in the Setup Program.
> Touch the icon «Upper thread tension».
> Move the slide using the touchscreen pen or the finger to increase or reduce the upper thread tension.
> Touch the yellow-framed icon to reset the alteration to basic setting.
