Abstract

A sprocket cover arrangement for a hand-held chain saw has a housing and a sprocket cover that has an opening and is connected to the housing. At least one stud bolt having a first end secured to the housing and having a second end that is a free threaded end is provided. The free threaded end projects through the opening of the sprocket cover to an exterior side of the sprocket cover when the sprocket cover is positioned in an operating position on the housing. A nut is screwed onto the free threaded end of the at least one stud bolt on the exterior side of the sprocket cover so as to secure the sprocket cover on the housing. The nut is secured captively, rotatably and with play in the opening of the sprocket cover.
