    摘要: A dust collector-equipped power cutter, which is easy to handle in operation and convenient for storage and transportation thereof and is capable of preventing dusty air from flowing back to the cutter portion when a cutting operation is interrupted, includes a main body, a cutter, a dust-sucking fan, and a dust hose assembly. The dust hose assembly includes a first dust hose section and a second dust hose section and a hose connector joining the first hose section and the second hose section. Each of the hose sections has a spiral rib on an outer peripheral surface, and the hose connector has a spiral groove on an inner wall of each end portion, the dust hose section and the hose connector being adapted to be interconnected with each other through a threaded engagement between the spiral rib and the spiral groove. The hose connector is provided with a check valve to prevent back flow when a cutting operation is interrupted or terminated.

    摘要: An engine-driven blower unit has a casing, an impeller provided inside the casing, and an engine. The casing has a first opening on its wall close to the cooling fan of the engine so that a portion of the air inside the casing is let out through the first opening toward the engine. A second opening is formed so that a portion of the air around the engine is lead to the inside of the casing, to the downstream of the first opening. Thereby, engine-cooling effect is improved, and operational noise is reduced.

    摘要: A hand lever device is adapted so that a throttle valve as a driven member can be adjusted appropriately in its degree of opening via a cable and kept at a desired degree of opening and yet immediately returned to the minimum degree of opening. The throttle valve can be brought to the degree of opening at which it had stood before it was returned to the minimum opening degree without the necessity of readjustment. The hand lever device comprises a main lever (30) and a sub-lever (60) which ice pivotally operated, wherein the sub-lever (60) is adapted to draw a cable (20) connected to a driven member (CV) via a pulley (50), and wherein the pulley (50) is moved by the main lever (30).

    摘要: A portable power working machine includes a small air-cooled internal combustion engine, a cooling fan, and a carburetor chamber housing therein an air cleaner. A dust-separating air duct is interposed between a region close to the cooling fan and the carburetor chamber housing, the dust-separating air duct being configured to separate dust included in an intake air from air by taking advantage of an air flow, thereby allowing clean air separated from the dust to be fed to the carburetor chamber housing and allowing the dust separated from the intake air to be sucked by the cooling fan.
