ABSTRACT:
A power tool is provided which includes a shaft rotatably driven by the motor and an axial lining in the central bore of the working element. A counterweight assembly is attached to the shaft for rotation therewith. A post on the counterweight assembly is insertable in the axial lining. A detent is mounted to the post and includes arcuate cam surfaces. The detent is movable between (1) an extended position relative to the post, and (2) a depressed position relative to the post wherein the axial lining engages the cam surfaces and allows the post to be inserted in the axial lining. A circumferential groove on the axial lining is capable of capturing the detent in the extended position to provide for substantially fail-safe operation of the tool with the post inserted in the axial lining.
