ABSTRACT:
The invention relates to a portable handheld work apparatus such as a motor-driven chain saw having an internal combustion engine mounted in a housing for driving a work tool. A cooling-air blower is mounted on one side of the housing. The cooling-air blower is covered by a blower cover having air-intake openings. The blower cover has a bearing lug facing toward the cooling-air blower. A pull-rope starter for starting the engine is held on the bearing lugs and the housing of the pull-rope starter is attached to the blower cover. The pull-rope starter housing is configured as a component separate from the blower cover in order to minimize the disturbance of the cooling-air inflow by the pull-rope starter housing. This component is attached at a spacing to the air-intake openings of the blower.
