ABSTRACT:
A method for controlling a hydraulic pump included by an apparatus, comprises the steps of: measuring a circumferential atmospheric temperature of the apparatus, comparing the measured circumferential atmospheric temperature with a first temperature to judge as to whether the measured circumferential atmospheric temperature is higher than the first temperature or not, and decreasing an output of the hydraulic pump when the measured circumferential atmospheric temperature is judged to be higher than the first temperature.
