Abstract: A hand-guided treatment device is configured for use in working positions tilted relative to each other by a tilt angle of at least 45° about a device longitudinal axis. The device has a device housing, a handle operating unit with a handle extending with a main direction component parallel to the device longitudinal axis and a finger-operable operating element within finger reach of the handle, and a display field arranged on an outside of the device housing with at least one optical display element. The display field is arranged offset relative to the operating element in a housing circumferential direction about the device longitudinal axis and extends in the housing circumferential direction over a housing edge and/or with a curved or kinked course.

Abstract: A handheld work apparatus has an electric motor and a voltage source for operating the motor. A manual actuation element provided on a handle of the apparatus is operated by a user and is provided for activating the motor. The actuation element is connected to a control unit which controls the energy supply from the source to the motor as a function of an operating signal of the actuation element. If the control unit is in a blocking state, the energy supply to the motor is blocked independently of the operating signal of the actuation element. After receiving a control signal, the control unit switches from the blocking state to a standby state to release an energy supply to the motor. The control signal is derived from a combination of an actuation stroke and an actuation time (?TB) of the actuation element. A method for activating the apparatus is also disclosed.

Abstract: A method controls the rotational speed limiting of an engine in a handheld work apparatus. The crankshaft of the engine drives a worktool via a clutch which engages in dependence on the motor rotational speed. Above an engaging speed of the clutch, a drive connection with the crankshaft is made and below the engaging speed, the drive connection is interrupted. A speed control unit monitors the rotational speed of the engine and includes a rotational speed lock circuit which limits the speed to a limit below the engaging speed. During the start of the engine, the lock circuit is switched on; it is switched off after the engine has been taken into operation when a deactivation signal is present, wherein the deactivation signal is generated when an operation change signal of the work apparatus is detected.

Abstract: A portable handheld work apparatus has an internal combustion engine (10) for driving a work tool. The engine (10) has a cylinder (25), a crankcase (26) and an ignition device. The work apparatus has a housing component which is made at least partially from an electrically non-conducting material. At least one electric component is provided on the housing component. The electric component is electrically conductively connected to at least one electric line (69, 70, 71, 72). A simple configuration of the work apparatus and a simple assembly can be achieved when at least one section of the electric line (69, 70, 71, 72) is embedded in the housing component.

Abstract: A vessel (1) of a portable handheld work apparatus is provided for liquid operating substances such as fuel, oil or the like. The vessel (1) has a vessel wall (2) of injection-molded plastic and a viewing window (3) integrated into the vessel wall (2). The viewing window is provided for viewing the fill level. The vessel wall (2) and the viewing window (3) are configured as a two-component injection-molded part. Mutually adjoining edges (4, 5) of the vessel wall (2) and the viewing window (3) have a tongue-and-groove connection (6) with at least one groove (7) and at least one tongue (8).

Abstract: A method for making a plastic molded part (12) includes injecting plastic (13) into a foil part (2) with plastic (13) being injected into an injection mold (7) at the rear side of the foil part. The plastic molded part (12) is especially a housing component of a portable handheld work apparatus. The method includes providing a plurality of foil parts (2) in a foil strip (1). Thereafter, the foil strip (1) is positioned in the work region of the injection mold (7). A foil part (2) is taken out of the foil strip (1) utilizing a grabber (6) and is placed in the injection mold (7). Thereafter, the foil part (2), which is placed in the injection mold (7), is back injected with the plastic (13).
