Thread Tension; Thread Sensor - Husqvarna Viking Designer topaz 25 User Manual

THREAD TENSION

Your machine automatically sets the best thread tension for
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.
Note: For decorative stitches and buttonholes the top thread should be
visible on the underside of the fabric.

THREAD SENSOR

If the upper thread breaks or bobbin thread is running low,
the machine stops and a pop-up message appears on the
GraphicDisplay.
If upper thread breaks: Re-thread the machine and close the
pop-up message by pressing the OK button. If bobbin thread
is running low: You can continue sewing without closing the
pop-up before the bobbin thread runs out completly. This
gives you an opportunity to plan when you want to change
your bobbin. When the bobbin is replaced with a full one,
press the OK button.
