Abstract
A combination handwheel/crank for a power tool, such as a radial arm saw or the like, is disclosed with the power tool having a base or frame, a component adjustably movable relative to the base and rotatably driven adjustment mechanism for moving the component relative to the base with this adjustment mechanism having a drive shaft. This crank assembly is provided for rotatably driving the drive shaft, this crank assembly having a hub adapted to securely receive the drive shaft with the hub having an enlarged hub body facilitating the precision manual rotary adjustment of the component. The crank assembly has a crank handle carried by the hub body and radially offset from the hub. The crank is pivotally movable with respect to the hub body between a folded position in which the crank is substantially coplanar with the outer surface of the hub body such that a user may readily manually grip the periphery of the hub body without interference from the crank handle for the precision manual adjustment of the component and an extended position in which the crank is radially offset from the hub body thereby to permit the coarse rotary adjustment of the component.
