Operating Instructions 581 - 00.0 - 02/201550
5.9.1 Adjusting the needle thread tension
The tension of the needle thread must generally be tighter than
the tension of the looper thread. The thread tension is electroni-
cally regulated. It comprises the main tension for the sewing
process and a remaining residual tension (cutting tension)
for
tightening the needle thread during the cutting operation under
the throat plate.
Regulate the residual tension (cutting tension) to suit the elasticity
of the needle thread used, so that the thread end hanging from
the needle is sufficiently long to ensure a safe sewing start.
To set the needle thread tension:
Step
1. Set the main tension for the sewing process using the control
panel (
8.1.5 Adjusting the thread tension, p. 95).
2. Set the residual tension (cutting tension) using the control
panel.
