Abstract:
1. An oil pulse tool comprising: a motor generating a driving force; an oil pulse unit including a shaft, the oil pulse unit being driven by the motor and generating an impact torque on the shaft when the motor reaches an impact position; and an output shaft on which a front end tool is attached, the output shaft being fixed to the shaft, a torque detecting sensor for detecting generation of an impact torque; and an operating portion configured to detect a time period between a first impact torque detected by the torque detecting sensor and a second impact torque detected by the torque detecting sensor, the second impact torque being smaller than the first impact torque; wherein the operating portion is configured to carry out a notification when the time period between the first impact torque and the second impact torque is less than a first predetermined evaluation value for the time period between the first impact torque and the second impact torque.
