NOTE: Shorten adjustment travel (-).
Increase adjustment travel (+).
To ensure a reliable setting of the adjustment travel, both adjusting nuts must be marked with a colored mark.
One full turn of the adjusting nut corresponds to an adjustment travel of 0.75 mm .
Example 1:
Actual value measured by the diagnostic function: +0.75 mm .
Required correction: +0.75 mm: 0.75 mm = +1.0 turns .
Adjust nut (1) in (+) direction by 1.0 rotation and then tighten nut (2).
Tightening torque 11 65 4AZ .
Example 2:
Actual value measured by the diagnostic function: -1.5 mm .
Required correction: -1.5 mm: 0.75 mm = -2 turns .
Adjust nut (2) in (-) direction by 2 rotations and then tighten nut (1).
Tightening torque 11 65 4AZ .
Check basic setting again using diagnosis.
