Abstract
A portable power working machine is disclosed, which is capable of effectively minimizing the clogging of the air cleaner, thereby dispensing with frequent maintenance. This portable power working machine comprises an air cleaner (30) having a base body case (32) provided with a clean air discharge port (33) for introducing the air cleaned into an intake port (25) of a carburetor (14), a filter (35) which is mounted on a filter mounting opening (32a) of base body case (32) so as to seal it, and a cleaner cover (37) which is attached onto the filter (35) so as to cover the filter (35) and to guide outside air toward the filter (35), while giving a predetermined directionality to the outside air. The air cleaner (30) is also configured to include a suction port (50) and a suction guiding member (55) both designed to discharge the dust out of the air cleaner (30) through a space formed between the filter (35) and the cleaner cover (37) as the dust adhered to the outside air side of the filter (35) is sucked out by taking advantage of a negative pressure to be generated by a fan (22).
