ELECTRIC WORKING MACHINE
An electric working machine includes an electric motor drivable by electric power from a battery on a machine body, a hydraulic device actuatable by power from the electric motor, a working device actuatable by hydraulic pressure of hydraulic fluid supplied from the hydraulic device, a switch switchable between a first position to permit actuation of the working device and a second position to not permit actuation of the working device, and a fluid temperature detector to detect a temperature of hydraulic fluid. While the electric motor is driven, when the switch is switched to the second position and the temperature of hydraulic fluid is within an allowable temperature range that is neither in a low temperature state nor a high temperature state, a controller is configured or programmed to control a rotation speed of the electric motor to a predetermined first rotation speed corresponding to a stopped state of the electric motor.
