Regulating The Speed; Adjusting The Upper Thread Tension - Bernina 590 Instructions Manual

> Hold the dual feed on the holder with two fingers, pull it down, then push backward, slowly letting it
slide upward.

5.3 Regulating the speed

The speed is infinitely variable with the slide-speed control.
> Move the slide-speed control to the left to reduce the speed.
> Move the slide-speed control to the right to increase the speed.

5.4 Adjusting the upper thread tension

The default setting of the upper thread tension is provided 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.
Alteration of the upper thread tension affect the currently selected stitch pattern or embroidery motif.
Permanent alterations of the upper thread tension for the sewing mode (see page 55) and for the
embroidering mode (see page 59) can be made in the Setup Program.
Prerequisite:
• In the Setup Program the upper thread tension has been altered.
