Adjusting the needle thread tension
The 3 tension-adjusting wheels on the tensioning screw triangle
determine the needle thread tension.
Figure 13: Adjusting the needle thread tension
The main tensioner (3) determines the normal tension during
sewing.
The additional tensioner (2) increases the tension during sewing,
e.g. for thickened seams. The additional tension (2) is switched
on and off using the keypad.
The additional tension (2) must always be selected lower than the
main tension (3).
In the basic position, the top of the adjusting wheel is flush with
the screw in the center.
To increase the tension:
• Turn the adjusting wheel clockwise.
To reduce the tension:
• Turn the adjusting wheel counterclockwise.
The pre-tensioner (1) holds the thread in position if main
tensioner (3) and additional tensioner (2) are open completely.
(1) - Pre-tensioner
(2) - Additional
tensioner
