1. The tension is created by the disks through
which the thread is led. The pressure on
these disks is regulated by the upper thread
tension dial (20).
The higher the number, the tighter
the tension.
NOTE: The tension is only activated by
lowering the presser foot.
2. There are several reasons, why it is
necessary to regulate the tension. Different
fabrics require different levels of thread
tension.
The required tension depends on the
closeness and thickness of the material, how
many layers of fabric are to be sewed, and
which stitch type you choose.
We recommend using an old piece of cloth
for sewing a test seam.
Please make sure that the tension
of the upper and under thread is even,
since otherwise the fabric could be puckered.

Note:
For normal operation the upper thread
tension dial should be set to 3.
