Thread tension
The thread tension is adjusted
automatically when you select a
stitch or an embroidery. This is
shown by the thread tension
indicator being reset.
You can also adjust the thread
tension by pressing the buttons
, see page 19. Using the
button (-) you decrease the tension
and using the button (+) you
increase the tension. The adjustment
affects all stitches and will remain
until the machine is turned off.
Normal thread tension is 4.
When selecting buttonholes and
decorative stitches the thread ten-
sion is reduced.
When topstitching with a coarse
thread in thick fabric, increase the
tension to 7-9.
When the machine is turned on, the
tension is set to normal
automatically.
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 material or, in the case
of decorative stitches, on the
underside.
Make a few tests on a scrap piece of
the material you are going to sew
and check the tension.
