Abstract: In order to create an engine more preferably for a small working machine, for example for garden, forest and landscape work or for an engine-operated tool and the like, with a carburettor unit for mixture provision, in which carburettor unit via an inlet pipe is connected with a cylinder of the engine, wherein the cylinder extends along its piston running direction from its crankcase side as far as to its head end, and wherein a holding device is provided which serves for the mechanical holding of at least the carburettor unit and at least comprises an elastic element with an improved arrangement of the carburettor unit and easy removability of the carburettor, i.e.

Abstract: A braking device is provided for braking or immobilizing a shaft in a work tool, particularly a saw chain, hedge shears or the like. The braking device has a brake band that at surrounds at least part of an area of the shaft, in which the brake band forms an effective plane, and two brake band holders with which the brake band may be placed under tension and released, in which at least one brake band holder is constructed movably, and in which a movable brake band holder is arranged with little space requirement in the braking device. At least one brake band holder is mounted outside the effective plane of the brake band so that it is rotatable about the axis of rotation or about an approximately parallel axis or shaft and/or so that it is able to be moved in a linear direction on a plane that is approximately orthogonal with the shaft.

Abstract: A work implement in the nature of a drive for a tool includes a starting and/or switching-off braking device for the tool. A brake button is provided which can be externally actuated by a user, with which a starting and/or switching-off brake can be released. A device is also provided which can change the rotational speed of the drive, the device having a throttle button capable of being actuated by the user from outside. The brake button and the throttle button are arranged on a handle so that they can be contacted simultaneously by the hand of a user, where the throttle button can be actuated when the starting and/or switching-off brake is applied.

Abstract: A coupling element is provided for a detachable plug connection of a guide tube, which is dividable into at least two sections, with a drive shaft mounted therein for torque transmission between an engine unit and a tool head of a hand-operated string trimmer. A first, upper guide tube section is arranged between the engine unit and the coupling element, and a second, lower guide tube section is arranged between the coupling element and a tool head. The coupling element has a coupling sleeve that provides both an exact alignment of the cutting tool as well as a simple and secure assembly of the guide tube sections. A latching connection with at least one latching element is arranged on the coupling sleeve so that it latches into place in only the correct rotational position on a latching seat of the guide tube section upon insertion of one of the guide tube sections into the coupling sleeve.

Abstract: The invention relates to a work implement including a drive which can be started by a cable pull starter, wherein the cable pull starter has a starter handle which is located in a holder in a rest position and which can be removed from the holder by a user for starting the drive. The work implement also includes a starting brake for a tool which prevents tool movements hazardous to the user directly after starting the drive, wherein a tripping mechanism disposed on the holder is provided for the starting brake, which by removing the starter handle from the holder automatically tightens the starting brake.

Abstract: A hand grip with half-shells is constructed so as to be able to be fastened to a tubular pipe, and is provided with a mounting opening for the tubular pipe which on the one hand is securely fastened to the tube and on the other hand does not have any intrusive bores in the grip region, in which there is to be a generous space available for a grip mechanism. Each half-shell is provided with a holding arrangement corresponding to the tubular pipe, so that the two holding arrangements form a form-fitting mounting for the respective half-shell on the tubular pipe.

Abstract: The invention pertains to a trimming device with a motor-driven cutting tool that is rotatable about a shaft and with a shell-like reel protector (100), wherein said trimming device can be operated with different cutting tools. In order to achieve a simple adaptation of the reel protector to the respective tool used, the invention proposes that the reel protector (100) includes a first shell (10) that is rigidly connected to the trimming device and a second shell (11) that can be displaced relative to the first shell (10) in the direction (A) of the shaft of the cutting tool.

Abstract: A hand-guided work implement, in particular hedge clippers, is provided which includes a drive having an internal combustion engine for a cutting tool and a handle for a user's hand and at least one other handle at a distance from said one handle for the other hand of the user. A throttle lever is provided on one handle and is capable of being actuated by the user's hand, which controls the power of the drive. At least one brake lever for a starting brake of the cutting tool is provided on the at least one other handle. The starting brake can be adjusted between a brake position and a cutting position.
