Abstract
There is provided a portable air blowing working machine capable of obviating frequent operation for the maintenance of air cleaner and hence capable of improving working efficiency. This working machine includes an internal combustion engine having the air cleaner disposed in the air-intake system thereof, and an air blower to be rotationally driven by the engine; which is characterized in that the air cleaner is provided with a suction port for in drawing in external air, with a filter member for cleaning air drawn from the suction port to thereby permit the cleaned air to be introduced into the engine, and with a discharge port for enabling part of the air drawn from the suction port to be discharged out of the air cleaner without permitting part of the air to pass through the filter member; and that an air flow directed to flow from the suction port to the discharge port is permitted to generate inside the air cleaner by making use of the suction force of the air blower.
