Embodiment Construction

[0019] figure 1 A motorized chainsaw 1 is shown with a saw sword protruding from a motor housing 2 5. The front handle 3 arranged at the motor housing 2 and the rear handle 4 for operating the motorized chain saw 1 . In the motor housing 2 there is a starting unit which will be described further later and which comprises an electric motor. The rear handle 4 has an upper handle region 6 , in which an accelerator lever 7 and a locking lever 8 are mounted. Furthermore, the rear handle 4 includes a lower handle area 9 which is designed as a receiving housing 11 for the battery pack 10 . The battery pack 10 is provided with a state-of-charge indicator, for example in the form of a lighting device 27 . Furthermore, in the lower handle area 9 there is a control for the start-up process, which will be mentioned later.

[0020] Arranged on the motor housing 2 in the vicinity of the rear handle 4 is an operating lever 13 which, in the exemplary embodiment, is designed as an operati...

Abstract

A handheld work apparatus having an internal combustion engine and an ignition is equipped with a start device for the engine. The start device includes an electric motor and, for driving the electric motor, a battery (10) is provided which is connected to the electric motor via a switching device. For simplifying the arrangement and for safe handling, a common operator-controlled element for switching on the ignition and for activating the start device is provided which can at least be set to a stop position (0), an operating position (I) and a start position, whereby the operating position (I) is between the stop position (0) and the start position.

Description

technical field [0001] The invention relates to a hand-operated (handgeführt) work implement with an internal combustion engine Background technique [0002] To start the internal combustion engine in hand-held power implements, a cord-operated device is usually used. Furthermore, it has been proposed in DE 102 01 562 A1 to provide a starter with a damper / energy storage device which is arranged centrally along the power transmission system between the drive element and the driven element. In this case, the buffer / energy storage device should be enabled to store power during the driving process of the drive element through which the power is delivered, and wherein the drive element is an electric motor which serves as the drive power source. Furthermore, a starting device for internal combustion engines of smaller single-cylinder units is known from DE 42 15 509 A1, wherein the starting device comprises an electric motor as starter motor, a reduction gear for reducing the ...
