1) Figure underlined is the setting.
2) Perform CO measurement and setting upstream of catalytic converter only if e.g. the max. permissible CO level at
exhaust tailpipe is exceeded during emissions test.

3) No harder valve seat rings installed, for this reason:
a) On engines without hydraulic valve clearance compensation, halve valve clearance inspection interval
b) On engines with hydraulic valve clearance compensation, check basic setting of hydraulic elements during maintenance service with additional work
every 45,000 and 60,000 km, set if necessary.
