Abstract: A handheld work apparatus has at least one tool which is driven by a combustion engine. A portion of an intake channel of the combustion engine is formed by an elastic connecting piece which has a first section and a second section between which an expansion fold is arranged. The expansion fold has a first side wall and a second side wall arranged downstream of the first side wall. A peripheral wall, which extends in the region of the largest outside diameter (a) of the expansion fold, is arranged in flow direction between the first side wall and the second side wall. The connecting piece has a stop for the expansion fold which prevents a segment of the first side wall adjoining the peripheral wall from bearing against the second side wall.

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.
