tension spring (E) until it "clicks" into place.

Thread tension, 835/855

Use the recommended top thread tension setting given on the
GraphicDisplay. You might need to adjust the top thread tension
for special threads, fabrics and/or techniques. To set the tension,
turn the numbered tension dial. The higher the number the
tighter the tension.
Normally top thread tension is set to around 4. When sewing
buttonholes and decorative stitches set thread tension to around
3. When topstitching with a heavy thread in thick fabric, increase
the tension to 7-9.
Make a few tests on a scrap piece of the fabric you are going to
sew and check the tension.
Correct and incorrect thread tension
To understand the correct thread tension, sew a few sample
straight stitches at different settings.
1. Begin with a tension that is too loose, i.e. set at the lowest
number. The bobbin thread will lie straight and the top thread
will be drawn to the underside of the fabric.
2. If you set the tension at the highest number, the bobbin
thread will be visible on the top side of the fabric. The seam
may pucker and the top thread might break.
3. The correct thread tension is set when the threads interlock
in between both fabric layers or, in the case of decorative
stitches, on the underside.

Automatic thread tension, 875 Quilt

The 875 Quilt model automatically sets the best thread tension
for the selected stitch and fabric. Go to the SET Menu to adjust
the thread tension for specialty thread, techniques or fabric (see
page 29).
