CAUTION!
A special process is used to match the pivot bolt and the self-locking nut. When
replacing, therefore, always exchange both the pivot bolt and the self-locking nut
for a new pair! Because of the special procedure an unscrewing of the nut while
working will be minimized and a resulting blade crack will be prevented.
The nuts can be unscrewed and retightened up to 10 times without affecting
service performance!
