Adjusting the upper thread tension

The basic setting of the upper thread tension is set automatically as soon as a stitch pattern or an embroidery
motif 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 or embroidery threads, the optimal tension may vary. Therefore it may
be necessary to adjust the upper thread tension according to the sewing or embroidering project as well as
the desired stitch pattern or the embroidery motif 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.
Alterations of the upper thread tension in the Setup Program affect the currently selected stitch or
embroidery patterns. Permanent alterations of the upper thread tension for the sewing mode (see page 50)
and for embroidery mode (see page 53) 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 to reduce the upper thread tension.
> Touch the yellow-framed icon to reset the alteration to basic setting.
