Abstract
A control method of a work machine in which a rotation number of a fan that takes outside air into an engine room accommodating an engine varies with a rotation number of the engine, includes: executing first control of regenerating a collecting filter unit that collects particulates contained in exhaust gas of the engine by a temperature rise of the exhaust gas; when the work machine is changed from a steady state to a specific state, executing second control of decreasing an amount of working oil discharged from a hydraulic pump by driving of the engine; and, when the first control and the second control are concurrently executed, executing third control of increasing the rotation number of the engine.
