Abstract:
1. A construction machine provided with an exhaust gas purifying device for an internal combustion engine, the construction machine comprising: an energy-wasting operation judging unit that judges whether or not an operation of the construction machine is an energy-wasting operation; a judgment result notifier that notifies a judgment result of the energy-wasting operation judging unit to an outside; a regeneration treatment judging unit that judges whether or not a regeneration treatment of the exhaust gas purifying device is to be conducted; and a notification restricting unit that restricts the judgment result notifier from notifying the judgment result of the energy-wasting operation judging unit, when the regeneration treatment judging unit judges that the regeneration treatment of the exhaust gas purifying device is to be conducted wherein, a plurality of work modes each having a different workload are allowed to be set in the construction machine, and the energy-wasting operation judging unit judges that the operation of the construction machine is the energy-wasting operation when the construction machine is operable in one of the work modes with a small load although the construction machine is set in another one of the work modes with a large load.
