6.4 Setting the Tension Regulator
The needle thread quantity required for the hook is adjusted with the tension regulator 2.
The setting is dependent on the following factors: - Material thickness
- Yarn characteristics
- Stitch length
A prescisely set tension regulator assures an optimal sewing result at the lowest
possible needle thread tension.
With a correct setting, the needle thread loop must glide over the thickest point of the
hook with little tension.
In position "
1
" of the tension regulator the maximum thread quantity is released.
In position "
5
" of the tension regulator the minimum thread quantity is released.
Caution Risk of Injury !
Set tension regular 2 only with the sewing machine turned
off.
–
Loosen screws 1 and 3.
–

The scale above the tension regulator serves as a setting aid.
–
Tighten screws 1 and 3.
Setting note:
For a correct setting of the tension regulator 2 the following condition must be met:
–
When the greatest thread quantity is required, the thread controller spring 4 must
be pulled approx. 0.5 mm up out of its upper end position.
This is the case when the needle thread loop passes the maximum diameter of the
hook.
