Abstract

[Problem] To provide a working machine control method, a working machine control program, a working machine control system, and a working machine, in which operation is less likely to be hindered even in a low temperature environment.[Solution] A control method of a working machine 3 is a control method of the working machine 3 including an electric motor 41 driven by electric power of a battery 50 and a hydraulic pump 42 driven by the electric motor 41 and configured to supply hydraulic oil to a hydraulic actuator. This control method includes: driving the electric motor 41 at a steady rotation speed when a monitored temperature is in a normal temperature region; and setting an upper limit value of a rotation speed of the electric motor 41 to a regulated rotation speed lower than the steady rotation speed when the monitored temperature is in a low temperature region lower than the normal temperature region.
