A construction machine provided with an exhaust gas purifying device for an internal combustion engine includes 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.

Construction machine and method for reporting quality of driving operations of construction machine

A guidance output device, which outputs guidance for improving fuel economy when an energy wasting operation is detected in a construction machine that is provided with an exhaust gas purifying device for an internal combustion engine, includes a regeneration process determining unit that determines whether a regeneration process is in progress in the exhaust gas purifying device. It also includes a guidance output restriction unit that restricts an output of the guidance for energy saving by the guidance output unit when the regeneration process determining unit determines that the regeneration process is in progress in the exhaust gas purifying device.
