*1: Indicates the value at the lowest cooling fan speed.
*2: Indicates the value of the engine alone (without cooling fan).
*3: The battery capacity (Ah) is indicated in the 5-hour rate value.
a The engine rated output is indicated in the net value and gross value. Gross denotes the rated output measured of
an independent engine. While, net denotes the value measured of an engine under the condition essentially the
same as that when it is installed on machine.
a Following shows the rated output (net) at the maximum cooling fan speed.
