Abstract
A power tool includes a housing, a blade assembly, a drive assembly within the housing for driving the blade assembly, and a cover that is coupled to the power tool and is movable between at least two positions. The blade assembly is fixedly retained by the power tool when the cover is in a first position and is detachable from the power tool when the cover is in a second position. The cover has tool-less means for coupling the blade assembly to the cover when the cover is in a second position.
