Abstract
A handheld work apparatus includes a fuel tank, into which a flexible fuel line projects. A suction head is arranged at the free end of the fuel line. The suction head is connected via the fuel line to a fuel supply device of an internal combustion engine of the work apparatus. The suction head has at least one weight member. The weight member is formed at least partially as a magnet to achieve good cleaning of the fuel without a substantial increase in the weight of the work apparatus.
