摘要： A hand-operated implement has a guide bar on which is fitted a cutting chain for cutting mineral and metal materials. The cutting chain is driven around the guide bar by a chain sprocket. The chain sprocket is arranged in a chain sprocket chamber which is delimited by a chain sprocket cover. A cutting element has an outer side facing a sidewall of the chain sprocket cover which lies in a first notional plane. The distance between the sidewall and the first notional plane measured perpendicular to the first notional plane and centrally between the top of the cutting element and the peripheral wall is less than approximately 0.8 cm over at least 30% of the section between a second notional plane containing the central axis of a fixing bolt on the guide bar and the exit opening at which the cutting chain leaves the chain sprocket chamber.
