Exhaust Emissions
The CO
value measured in the EU type
2
approval procedure is specified at
www.stihl.com/co2.
The measured CO
value was
2
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.
