Abstract

PURPOSE: To facilitate the fitting of a socket bit to a bolt by a method wherein the socket bit is fitted to the hexagonal head of the bolt in the condition of the low- speed rotation and then the speed is shifted to a high speed.
CONSTITUTION: By the operation of the lever 3 of a power driver 1, the compressed air is supplied to a motor through a bypass airing pipe with a flow-rate control valve 30 and the socket bit 2 driven by the motor is made to advance with low-speed rotation to fit to the head of the bolt 24 which is chucked at the tip thereof. Under the condition, the contact of a limit switch is shifted, an electromagnetic valve 34 is demagnetized, the compressed air is supplied to the motor part from the main airing pipe 35, the motor is shifted to the original high-speed rotation, and thereby the bolt 24 is tightened at a high speed.
