Zusammenfassung: | The present invention relates to a motor-driven IMPLEMENT HAVING an IMPROVED CARBURETTOR PREHEATING apparatus, wherein motor-driven implement such as a hand-held tool or device for garden and landscape maintenance, includes an internal combustion engine having at least one cylinder and at least one carburettor, which is disposed in a carburettor chamber, is separated by an intermediate wall from an engine compartment. A housing is provided which at least partially encloses the engine compartment so that an upper part of the cylinder extends in the direction of the housing, and a fan wheel is further provided by which means air from the engine compartment can be introduced through a warm air opening in the intermediate wall into the carburettor chamber. For the motor-driven implement to have an improved carburettor pre-heating which enables easier operation, it is proposed that the warm air opening is disposed in the area of the intermediate wall which is disposed adjacently to the upper part of the cylinder. |
