Caution – Risk of Injury !
Turn the main switch off.
Adjust thread regulator only when the automatic bartacker is switched
off.
The thread regulator 3 is used to control the quantity of needle thread
required by the stitch formation.
The best sewing results can only be ensured when using a precisely
adjusted thread regulator.
At the properly adjusted setting, the needle thread loop must be able to
slide over the thickest section of the hook.
–
Loosen screw 1.
–
Change the position of the thread regulator 3.
Thread regulator to the left = more thread.
Thread regulator to the right = less thread.
–
Tighten screw 1.
Settings note:
If the largest thread quantity is required, the thread controller spring 2
must be pulled down by approx. 0.5 mm from its upper end position.
This occurs when the needle thread loop passes the section of the
hook with the widest diameter.
