Setting the needle thread tension

Pic. 9: Setting the needle thread tension
(1) - Auxiliary tensioner
Increasing the tension:
1. Turn the regulating knob clockwise.
Reducing the tension:
2. Turn the regulating knob counterclockwise.
Setting the auxiliary tensioner (1)
Adjust the auxiliary tensioner (1) so that it has as small tension as
possible, but high enough so as the thread cannot be pulled out
from tensioner (1) at the material removing after previous trimming
(when the tensioner (2) is opened - switched off).
Information
Auxiliary tensioner (1) is never switched off.
Setting the main tensioner (2)
Regulate the thread tension with the tensioner (2) until you achieve
a good interlacing of the threads ( p. 44).
