Incorrect Thread Tension - Husqvarna Lily 555 User Manual

Thread tension
Always use the recommended set-
ting given on the Info-display to
start with (see page 19).
You can adjust the thread tension by
turning the dial which is numbered.
The higher the number the tighter
the tension. Normal thread tension is
number 4.
When sewing buttonholes and deco-
rative 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
1
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 hig-
hest number, the opposite will
occur, and the seam may pucker.

3. The correct thread tension is pro-
vided when the threads interlock
in the middle of both layers of
material or, in the case of decora-
tive stitches, on the underside.
Make a few tests on a scrap piece
of the material you are going to sew
and check the tension.
