摘要： A work apparatus has an internal combustion engine for driving a work tool of the work apparatus and a fuel pump which is driven by the engine and delivers fuel from a fuel tank to the engine. The work apparatus has a feed pump which is to be actuated manually by the operator. The fuel pump and the feed pump form one component which is arranged outside the fuel tank. The fuel tank has a tank wall which delimits the tank interior. An advantageous arrangement arid satisfactory cooling of the component are achieved if the component is arranged at least partially on the tank wall.

摘要： A chainsaw having a drive motor. The chainsaw has a fixed part and a movable part. The guide bar is retained on the fixed part in a manner braced between the fixed part and a tensioning element. The movable part is shiftable in a longitudinal direction with respect to the fixed part in order to tension the saw chain with the tensioning element released. The chainsaw has a stop face and a tensioning face. At least one additional contact face that is firmly connected to the fixed part in the longitudinal direction and at least one additional contact face that is firmly connected to the movable part in the longitudinal direction are arranged between the stop face and the tensioning face. All the contact faces lie one after another in the flux of force from the tensioning element to the fixed part.

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.

摘要： A power tool has guide bar guiding a saw chain. A drive motor with a sprocket drives the saw chain. A sprocket compartment of the power tool housing has a peripheral wall adjacent to a roof of the saw chain and an ejection opening for cut material. The guide bar has a longitudinal center axis intersecting the saw chain in first and second deflection areas at the sprocket and the nose of the guide bar. The sprocket compartment has an exit opening where the saw chain exits. The peripheral wall of the sprocket compartment and the roof of the saw chain are disposed at a spacing relative to each other that, when the saw chain is standing still, is less than approximately 18 mm at least across 50% of a stretch from the first deflection area to the exit opening and across an entire saw chain width.

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 cutting chain for a hand-operated implement for cutting metal and mineral materials such as a stone cutter has central connecting links which are connected to one another by lateral connecting links. The central connecting links comprise first central connecting links which each have a drive tooth. The cutting chain has two central connecting links with drive teeth shaped differently to the drive teeth on the first central connecting links; or located a different distance from the leading drive teeth; or having no drive teeth. A hand-operated implement for cutting mineral materials has a drive motor which drives the cutting chain around a guide bar by a drive sprocket. The cutting chain is guided round part of the circumference of the drive sprocket and round a nose sprocket on the guide bar. The drive sprocket or nose sprocket have different first and second areas matched to the cutting chain.

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.
