ABSTRACT:
It is an object of the present invention to provide an effective technique to improve ease of operation of the power impact tool. The power tool of the present invention includes a tool body, a tool bit, a motor, first and second switches and a mode changing mechanism. The motor is driven only when both switches are in an on position. The first switch is biased in the off position. The second switch is biased in the last position operated. The mode changing mechanism switches between hammer operation modes such that in the first hammer mode, the user actuates the first switch while the second switch is locked in the on position and in the second hammer mode, the first switch is locked in the on position while the second switch is actuated. In the second hammer mode, actuating the second switch similar to a toggle switch operates the tool.
