Beschreibung
Zusammenfassung:	A handheld work apparatus has a tool, a combustion engine for driving the tool, a manually actuated pull-rope starter for the combustion engine, and a stop button configured to be actuated by an operator for switching off the combustion engine. A throttle element is arranged in an intake channel of the combustion engine. The work apparatus has a control device for activating a spark plug and a fuel valve of the combustion engine. The control device has a starting mode wherein the combustion engine can be started via the pull-rope starter, and an operating mode wherein the operator can activatethe combustion engine by adjustment of the throttle element in order to vary a rotational speed of the combustion engine. The operating mode and starting mode differ in terms of the control, via thecontrol device, of ignition time and fuel quantity to be supplied. When the combustion engine is started from the switched-off state, the control device is automatically in starting mode, such that after the combustion engine is switched off, the work apparatus is immediately ready for restarting via the pull-rope starter.
