发明名称 Rechargeable Electric Tool
摘要 A rechargeable electric tool includes a warning device which monitors a voltage of a power source battery and indicates a warning by means of an LED or a buzzer when the power source voltage is reduced to be equal to or lower than a reference voltage. The tool is configured such that, even when the warning is indicated, a control to interrupt a power supply to a motor is not performed, thereby enabling a usual operation in response to an activating operation on a trigger switch.
