5.3 Adjusting the thread tensions
The thread tension of the needle thread should be tighter than that
of the looper thread. Overly tight thread tensions cause the material
to be pulled together.
Overly loose looper thread tensions can cause missed stitches.
5.4 Removing a thread break
Fig. 11: Thread break
On the sewing head there are two thread monitors, whose switching
flags are released, if the needle or looper thread is torn. In this case, the
automatic sequence is stopped and the LEDs on the sewing head indicate
whether it is the needle or looper thread that is torn.
To remove a thread break:
1. Bring the needle bar into the top position by turning the hand wheel.
2. Swing the sewing head out. For this purpose, pull the magnetic roller
downwards,  5.7.1 Swinging the sewing head in and out, pg. 31.
