摘要： A chainsaw having improved cutting workability is provided. A chainsaw (10) is used to cut an object to be worked by a saw chain (22). A chainsaw main body (12) is provided with an electric motor (11) and a sprocket (19), and a guide bar (21) around which the saw chain (22) is wound is provided on the chainsaw main body (12). The guide bar (21) is attached to the chainsaw main body (12) by a screw member (36) serving as an attaching member. A load sensor (41) detects whether or not the guide bar (21) is attached to the chainsaw main body (12). Rotation of the saw chain (22) is prohibited based upon a signal from the load sensor (41) when the guide bar (21) is not attached to the chainsaw main body (12).

摘要： To provide an engine-operated working machine capable of preventing an engine from stopping due to fouling on a spark plug while suppressing an increase in the speed of the engine during starting. The engine is configured such that, during the starting of the engine, when it is being detected that throttle opening has been set at a starting position, if it is detected that the engine speed has exceeded a predetermined speed slightly lower than a speed when a centrifugal clutch becomes an engaged state, a control unit retards the ignition timing from a general angle (for example, 25 degrees) to a first angle (-25 degrees) BTDC, and then advances the ignition timing to a second angle (+10 degrees) at predetermined intervals (for example, at intervals of 10 cycles), and holds the ignition timing at the second angle for a predetermined time period (for example, a time period corresponding to 1 cycle), thereby preventing the engine from stopping due to fouling on the spark plug while suppressing the engine speed at the speed when the centrifugal clutch becomes the engaged state, or less.

摘要： The fastening tool includes a housing, a trigger, a cylinder, a piston, and a main valve. The main valve allows a communication between the cylinder and the first air chamber in conjunction with an operation of the trigger. The housing is formed with a first air chamber, a second air chamber, and a third air chamber. The second air chamber is communicated with the cylinder in conjunction with a movement of the piston. The third air chamber accumulates or discharges the compressed air in the first air chamber in conjunction with the operation of the trigger. The cylinder is movable between a first position where the cylinder upper chamber being in communication with the first air chamber, and a second position where the cylinder upper chamber being blocked from the first air chamber based on a differential pressure between the second air chamber and the third air chamber.

摘要： To provide an engine working machine which is capable of reducing an exhaust sound while maintaining a compact size and a sufficient engine output and is also capable of reducing a vibration sound generated by a vibration of a wall surface of a muffler. An engine (36) is configured such that: a driving shaft direction of the engine (Y-direction), an opening direction of an exhaust port (Z-direction), and an operation direction of a piston (X-direction) are substantially perpendicular to each other; a muffler (4) is fastened to a proximity of an exhaust port (24) of the engine (36); the muffler (4) has a shape extending in a vertical direction and is extended toward a downward direction lower than a vertical plane (72) passing a lower end portion of a cylinder; and the muffler (4) has a protrusion portion (32) protruding towards a center direction of the engine (36) so as to obtain a volume corresponding to a space (64). Since the muffler (4) is largely extended in a downward direction, a fuel tank (22) is provided to be offset to a left side (- Z-direction), and a left end portion of the fuel tank is extended upward like an arrow (80) so as to obtain a volume corresponding to a space (68).
