Patent AT-E401210-T1: [Translated] WORKING MACHINE

A hybrid system working machine, during a normal working time, operated by a normal operation mode that the output of a power generator (13) and the accumulated power of a capacitor (13) are used while the engine (11) is operated over a high-efficiency range at a low output. Switching of a selector switch to a high-speed running mode position and running operation enable long-distance and high-speed running of an increase in engine output by a high-output operation mode.
