32.9 Exhaust Emissions
The CO value measured in the EU type appro‐
2
val procedure is specified at
www.stihl.com/co2
in the product-specific technical data.
The measured CO value was determined on a
2
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 mainte‐
nance described in this User Manual. The oper‐
ating license shall be void if the engine is modi‐
fied in any way.
