Thread Tension - Husqvarna Viking Scandinavia 100 User Manual

Procedures

Thread tension

You can adjust the thread tension by turn-
ing the dial which is numbered. The higher
the number the tighter the tension. Normal
thread tension is number 4.
When sewing buttonholes and decorative
stitches set thread tension to number 3.
When topstitching with a coarse thread in
thick fabric, increase the tension to 7-9.
Correct and Incorrect Thread Tension
To understand the correct thread
tension, sew a few sample stitches at
different settings.
1. Begin with a tension that is too loose,
i.e. set at "1". The lower thread will lie
straight and the upper thread will be
drawn down on the underside.
2. If you set the tension at the highest
number, the opposite will occur, and the
seam may pucker.
3. The correct thread tension is provided
when the threads interlock in the middle
of both layers of fabric or, in the case of
decorative stitches, on the underside.
Make a few tests on a scrap piece of the
fabric you are going to sew and check the
tension.
