*Engine power values are as rated by the engine manufacturer.
NOMINAL POWER
A new machinery directive (2006 /42 /EC) came into force on January 1, 2010, requiring manufacturers to declare the nominal power of engines, in kilowatts (kW). The power rating of the engines indicated
is the average net power output during a normal working situations and meets applicable noise regulations (at specified rpm, see owner manual) of a typical production engine for the engine model measured to SAE standard J
1349 / ISO 1585. Mass production engines may differ from this value. Actual power output for the engine installed in the final machine will depend on the operating speed, environmental conditions and other variables.
