Claims (6)

  A motor as a drive source;
  A tip tool driven by the motor;
  A light emitter capable of irradiating the tip tool;
A power tool having
  When the temperature of the motor reaches a first temperature, the light emitter is in a first driving state,
  When the temperature of the motor reaches a second temperature higher than the first temperature, the light emitter enters a second driving state.   A motor,
  A switching element;
  First means for performing a first action;
  A temperature abnormality detecting means for detecting a temperature abnormality of at least one of the motor and the switching element;
  Control means for controlling the first means to stop the first action when the temperature abnormality is detected by the temperature detection means while the first means is performing the first action; ,
An electric tool comprising:   A motor,
  A switching element;
  First means for performing a first action;
  A temperature abnormality detecting means for detecting a temperature abnormality of at least one of the motor and the switching element;
  Control means for controlling the first means to perform the first operation when the temperature abnormality is detected by the temperature detection means in a state where the first means does not need to perform the first operation;
An electric tool comprising:   A motor as a drive source;
  A tip tool driven by the motor;
  A light emitter capable of irradiating the tip tool;
A power tool having
  A power tool characterized in that the light emitter flashes when the temperature of the motor becomes high.   A motor as a drive source;
  A tip tool driven by the motor;
  A light emitter capable of irradiating the tip tool;
A power tool having
  When the temperature of the motor reaches a first temperature, the light emitter is in a first driving state,
  When the temperature of the motor reaches a third temperature lower than the first temperature, the light emitter enters a third driving state.   A motor,
  A tip tool driven by the motor;
  A light emitter capable of irradiating the tip tool;
  An operation unit for turning on and off the light emitter;
A power tool having
  When the temperature of the motor reaches a predetermined temperature with the light emitter turned on, the light emitter is turned on after blinking the light emitter, and the temperature of the motor is changed with the light emitter turned off. A power tool configured to turn off the light-emitting body after blinking the light-emitting body when the temperature reaches a predetermined temperature.
