Caution: Risk of injury !
Switch the main switch off.
Adjust the thread regulator only with the sewing unit switched off.
With the thread regulator 3 the needle thread quantity required for the
stitch formation is regulated.
Only a precisely adjusted thread regulator guarantees an optimum
sewing result.
When the thread regulator is adjusted correctly, the needle thread loop
must slide over the thickest spot of the hook with low tension.
–
Loosen screw 1.
–
Change the position of the thread regulator 3.
Thread regulator to the left = larger needle thread quantity
Thread regulator to the right = minor needle thread quantity
–
Tighten screw 1.
Adjustment hint:
If the largest thread quantity is required, the thread controller spring 2
must be pulled up by approx. 0.5 mm from its lower end position. This
is the case when the needle thread loop passes the maximum hook
diameter.
