PROBLEM TO BE SOLVED: To provide a working machine suppressing abnormally rising in fuel temperature of a common rail 120 to prevent operating efficiency from dropping. SOLUTION: The working machine includes a diesel engine 70 with the common rail 120 and has such a mechanism as to drive working portions 2, 5, and 8 by the output of the diesel engine 70. The working machine also includes: a fuel temperature sensor 321 for detecting the fuel temperature in the common rail 120; and an overload alarm 327 for warning an operational state that the working portions 2, 5, and 8 are in operation under overload state, and the overload reference levels for the working portions 2, 5, and 8 to which overload warnings are to be given from the overload alarm 327 are set in multiple stages.
