Automatic needle positioning for seam start
The needle should be very close to the material before starting in
order to find the exact position for the start of the seam. In order
to adjust the needle height to the material thickness, the needle
can be slowly lowered downward by pressing on the electronic
handwheel (1).
1. Press down on electronic handwheel (1).
2. Only let go once the tip of the needle is at the desired height.
3. Confirm the new setting by pressing down on the wheel again.
5.7 Thread tension
The tension of the needle thread and hook thread determines
where the thread interlaces.
Correct setting
The threads should normally interlace in the exact middle of the
material. When setting, typically only the tension of the needle
thread is altered, while the tension of the hook thread remains
unchanged.
(1) – Equal tension of needle and hook threads
(2) – Hook thread tension greater than needle thread tension
(3) – Needle thread tension greater than hook thread tension
