19.4 Exhaust Emissions
The CO
2
value measured in the EU type approval procedure 
is specified at www.stihl.com/co2.
The measured CO
2
value was determined on a 
representative engine in accordance with a standardized 
test procedure under laboratory conditions and does not 
represent either an explicit or implied guarantee of the 
performance of a specific engine.
The applicable exhaust emission requirements are fulfilled 
by the intended usage and maintenance described in this 
instruction manual. The type approval expires if the engine 
is modified in any way.
