Abstract
Disclosed is a construction machine which comprises: a command changing regulation section; a loading device for imposing, on an engine, a load for raising an exhaust temperature of the engine up to a value at which particulate matter accumulated in a filter is burnt; and an instruction section for instructing the loading device to perform an operation for loading the engine. The instruction section prohibits the loading device from changing a loading level on the engine, during a period where a manipulation-state detection section detects a presence of a manipulation of a manipulation section. The command changing regulation section is set to a changing permission mode for permitting a value of a command which is to be assigned to an actuator control valve, to be changed according to changing a value of a command to be output from a manipulation device, during a period where the loading level is constant.
