1-2 Technical parameters
The rated power of the engine indicated in the Manual is the net output power (net power) at 3,600 rpm of an
engine under the production status measured in accordance with SAE J1349. For mass production engines, the
value may vary.
The actual power of engine installed on the terminal may vary in output, which depends on several factors
including the rotating speed of engine during practical use, environmental conditions, maintenance and other
variants.
