摘要： The invention relates to a work device with a guide rail (4) on which a chain (5) is driven in a circulating manner. The work device has a clamping device (15) for the chain (5). The clamping device (15) has a clamping element (16) which acts on en the guide rail (4) in the direction (19) of the longitudinal central axis (18) of the guide rail (4). The clamping device (15) has a rotatably mounted adjusting element (17) which is connected to the clamping element (16) via a threaded connection (20). A rotation of the adjusting element (17) about its rotational axis (21) causes a movement of the clamping element (16) in the direction (19) of the longitudinal central axis (18) of the guide rail (4). The outer circumference of the adjusting element (17) has a threaded portion (22) with at least one turn (23), said threaded portion being provided for engaging with at least one threaded portion (24) of the clamping element (16). The adjusting element (17) has an actuating contour (39) so that a user can rotate the adjusting element (17), said actuating contour comprising at least one depression. The largest spacing (b) between the threaded portion (22) of the adjusting element (17) and the rotational axis (21) is at least as large as the largest spacing (a) between the actuating contour (39) and the rotational axis (21).

摘要： A work apparatus has a work tool and a combustion engine for driving the work tool and further includes a start enrichment device for the combustion engine. The start enrichment device has a start position and is actuated via an operating mode selector. The work apparatus has a braking arrangement which brakes the work tool in the actuated position and releases the work tool in the unactuated position, and also an actuating device for the braking arrangement. To ensure that the start position can only be engaged when the braking arrangement is actuated, the work apparatus has a blocking device which prevents engagement of the start position in a blocking position. The braking arrangement is coupled to the blocking device such that the blocking device is in the blocking position with the braking arrangement in the unactuated position.

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.

摘要： A handheld work apparatus has a guide bar having a periphery along which a chain runs. The work apparatus has a housing and a fastening arrangement for fixing the guide bar to the housing. The fastening arrangement has an actuating device which can be actuated in a fastening direction in order to fix the guide bar. The work apparatus has a tensioning device to tension the chain. The tensioning device includes a tensioning spring. When the fastening arrangement is loosened, the tensioning spring exerts a force in a tensioning direction of the chain on the guide bar. Simple operation and a simple construction are achieved if the tensioning spring is in operative connection with the actuating device and is tensioned during actuation of the actuating device in the fastening direction.
