The method automates the processes of excavating, digging or loading in the electronic & hydraulic type excavator so as to improve the work efficiency. The method comprises the steps of: inputting an angle, a distance and a height of a target position of a bucket; actuating a proportional control valve or a spool of a servo valve in order to move the bucket if the data sensed from a position sensor, installed at an end of an excavator arm, corresponds to the input data; driving the bucket cylinder and performing a bucket out if the data sensed from angle sensor, installed at a swing part and joints of a boom and the arm, corresponds to the input data; controlling the speed of bucket out operation based on the data from a load cell installed at the bucket.
