Abstract:
1. A method for providing in a hand-held power tool electric energy for an engine control unit before start of an internal combustion engine of the power tool that is to be started mechanically by a rope starter, the method comprising the steps of providing a voltage source as a voltage supply for the engine control unit, wherein the voltage source provides electric energy for operating the internal combustion engine and wherein the voltage source is driven by a mechanical drive action; an operator driving the mechanical drive action, prior to a first rope starter pull being carried out, to generate electric energy by the voltage source before start of the internal combustion engine; storing the electric energy generated by the voltage source in a rechargeable energy storage device arranged within the power tool; and supplying the electric energy stored in the energy storage device to the engine control unit upon carrying out the first rope starter pull for starting the internal combustion engine.
