Abstract
A working machine includes an electric motor, a working device driven by power of the electric motor, an operation device to operate the working device, an operation locker switchable between an enabling position at which an operation of the working device by the operation device is enabled and a disabling position at which the operation is disabled, a cooler including an electric cooling fan, a temperature detector to detect a cooling target temperature, which is the temperature of a cooling target to be cooled by the cooler, and a controller to control a fan rotational speed, which is the rotational speed of the cooling fan, in accordance with the cooling target temperature detected by the temperature detector. The controller changes a characteristic of the fan rotational speed with respect to the cooling target temperature depending on whether the operation locker is in the enabling position or in the disabling position.
