22.6 Exhaust Emissions
The CO value measured in the EU type approval

procedure is specified at www.stihl.com/co2.
The measured CO 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 mainte‐
nance described in this instruction manual. The
type approval expires if the engine is modified in
any way.
