Abstract

A starter device for an internal combustion engine has a rope pulley and a starter rope wound onto the rope pulley. A starter handle is fastened to the starter rope. A rope guide with a first deflection roller is provided. A rope outlet opening is arranged along a circumferential section of the first deflection roller and extends along the circumferential section of the first deflection roller about a peripheral angle of the first deflection roller of at least 60°. The rope guide guides the starter rope from the guide pulley to the rope outlet opening of the starter device. A guide element is arranged at rope outlet opening and holds the starter rope in the rope outlet opening. The starter handle can be positioned relative to the rope outlet opening at different orientations and enables ergonomic starting of the internal combustion engine of a backpack power tool.
