Upper thread tension
Basic settings are applied automatically when a stitch pattern or program 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 lower
thread.
In case 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 fabric and the desired stitch pattern.
Higher upper thread tension = the upper thread is tightened, which
pulls the lower thread up to the top of the fabric.
Lower upper thread tension = the upper thread is loosened, which
enables it to be pulled to the back of the fabric.
