摘要： A trimmer head for mounting on a drive shaft of a trimmer has a housing and a trimmer line spool for winding and unwinding a trimmer line. The trimmer line spool is rotatably supported in the housing about an axis of rotation. The trimmer line spool has a first rotational direction in relation to the housing and a second rotational direction in relation to the housing, wherein the second rotational direction is opposite to the first rotational direction. A counting device detects a residual trimmer line length of the trimmer line remaining on the trimmer line spool. The counting device is connected to the trimmer line spool such that the counting device counts up when the trimmer line spool rotates in relation to the housing in the first rotational direction and counts down when the trimmer line spool rotates in relation to the housing in the second rotational direction.

摘要： The invention relates to a method for adapting the composition of a mixture of fuel and combustion air. The mixture is supplied to a combustion chamber of a mixture-lubricated combustion engine in a work apparatus. The fuel is supplied to the combustion engine via a controlled fuel valve. In an operating state (I) of the combustion engine, the quantity of fuel is metered by the fuel valve. For the purpose of adapting the composition of the mixture, the combustion engine is shifted into a special operating state (II) which differs from the normal operating state (I). After starting, the combustion engine is operated in a first rotational speed range (B) for a prespecified operating time (Tmin), wherein, after the prespecified operating time (Tmin) has elapsed, the operating state (II) for adapting the composition of the mixture is initiated by a prespecified user action.

摘要： 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 (ΔTB) of the actuation element. A method for activating the apparatus is also disclosed.

摘要： The invention relates to an electrical work apparatus including an apparatus housing having an electric motor for driving a work tool, a control unit for putting the electric motor into operation, a handle housing having at least one handle for guiding the work apparatus, and a receiving cavity, realized in the handle housing, having an insertion opening for a battery pack for operating the electric motor. For the purpose of decoupling the battery pack in respect of vibration, the handle housing, together with the receiving cavity for the battery pack, is decoupled from the apparatus housing via one and the same antivibration element. A vibration gap is realized between the apparatus housing and the handle housing, wherein the antivibration element at least partly bridges the vibration gap.
