摘要：
충전설비까지도달할수 없게되는상태를회피하면서작업을행할수 있는배터리식작업기계를제공한다. 컨트롤러는, 배터리의잔량이미리설정된제1 임계값을하회하였을때, 전동기의회전수가목표회전수로유지되도록인버터를제어함과함께, 제1 통보장치를작동시키고, 주행모드지시장치로부터의입력에관계없이, 주행모터를배기용적이대용량이되는주행 1속측으로전환한다.
摘要（英）：
A battery-operated working machine capable of performing work while avoiding a state in which it becomes impossible to reach a charging facility is provided. The controller controls the inverter so that the rotation speed of the motor is maintained at the target rotation speed when the remaining amount of the battery is less than the preset first threshold value, operates the first notification device, and input from the driving mode indicating device. Regardless, the travel motor is switched to the first travel speed side where the exhaust volume becomes large.
