Hand-operated implement comprising a cutting chain for cutting mineral and metal materials

A hand-operated implement comprising:

• a housing;
• a drive motor arranged in the housing;
• a guide bar fixed to the housing;
• a cutting chain, fitted to the guide bar, for cutting mineral and metal materials;
• the cutting chain comprising at least one cutting element which has a top facing away from the guide bar;
• a chain sprocket chamber disposed at the housing;
• a chain sprocket arranged in the chain sprocket chamber;
• the cutting chain being driven around the guide bar in a direction of travel via the chain sprocket by the drive motor;
• a device for feeding liquid to the cutting chain;
• the guide bar having a longitudinal central axis bisecting the cutting chain adjacent to the chain sprocket in a first turning area and adjacent to the nose of the guide bar in a second turning area;
• the cutting chain being driven in a first section from the first turning area to the second turning area in the direction of travel and in a second section from the second turning area to the first turning area in the direction of travel;
• a chain sprocket cover connected to the chain sprocket chamber and having a sidewall that delimits the chain sprocket chamber;
• the at least one cutting element having a top provided with a longitudinal edge, wherein the longitudinal edge faces the sidewall of the chain sprocket cover;
• the chain sprocket chamber having an entry opening where the cutting chain enters the chain sprocket chamber and further having an exit opening where the cutting chain exits the chain sprocket chamber;
• the chain sprocket chamber having a peripheral wall and at least one outlet opening formed at the peripheral wall;
• the at least one cutting element having an outer side that is facing the sidewall and is positioned at least partially in a first notional plane;
• a first fixing bolt securing the guide bar to the housing;
• a second notional plane perpendicular to the longitudinal central axis of the guide bar, wherein a central axis of the first fixing bolt is positioned in the second notional plane;
• a distance between the sidewall and the first notional plane, measured perpendicular to the first notional plane and centrally between the top of the at least one cutting element and the peripheral wall, is less than approximately 0.8 cm over at least 30% of the stretch extending between the second notional plane and the exit opening.
