Important

4.7 Thread tension
Together with the hook thread tension, the needle thread tension
influences the final seam pattern. With thin sewing material, ex-
cessive thread tension can lead to undesired ruffing and thread
breaking.
Proper setting
If the tension of needle thread and hook thread is identical,
the thread interlace lies in the middle of the sewing material.
Adjust the needle thread tension so that the desired seam pattern
is achieved with the lowest possible tension.
