摘要： A bush cutting machine comprises a clutch case attached to a front part of an engine, an operation rod extending forwardly from the clutch case and having a brake lever, a cutting blade provided at a distal end of the operation rod, and a transmission shaft passing through the operation rod for transmitting drive power to the cutting blade. A brake drum is housed in the clutch case for braking the rotation of the cutting blade. A brake arm is swingably attached to a front wall of the clutch case closely to the brake drum. The brake arm carries at one end thereof a brake shoe for press contacting an outer peripheral surface of the brake drum. A brake wire is mounted between the brake lever and brake arm. The brake wire is disposed to extend along either external surface of the operation rod.

摘要： An operation lever unit includes an operation handle attached to an operating rod of an engine-powered portable working machine. The operation handle is equipped with a throttle lever for regulating the power of an engine, a lock lever for holding the throttle lever in a desired position, and a secondary throttle adjustment lever for achieving a fine adjustment of the position of the throttle lever. To hold the throttle lever in the desired position, the throttle lever is forced against a portion of the operation handle by the action of a thrust cam mechanism disposed between the throttle lever and the lock lever. For achieving the fine adjustment of the throttle lever position, the secondary throttle adjustment lever is forced by a thumb of the operator to forcibly turn the throttle lever against a frictional force acting between the throttle lever and the handle portion.

摘要： An operational lever for a bush cutter includes a handle housed in a handle case, a throttle lever pivotally mounted to the handle, and a lock lever pivotally mounted to the handle. The operational lever further includes a torsional coil spring which exerts a resilient force on the lock lever. The lock lever is pivoted from an initial position to a pivoted position by an operator's palm. The throttle lever is then pivoted to a half-pivoted position by operator's fingers. When the palm is moved a small distance away from the handle case with the throttle lever held in the half-pivoted position, the lock lever is pivoted back towards the initial position by a resilient force of the spring. This causes a curved surface of a side protrusion portion of the lock lever to engage or abut on a side of a protrusion portion of the throttle lever. This arrangement is advantageous in that even when the operator takes her or his fingers off the throttle lever, the throttle lever is locked by a friction force produced between the curved surface and the side.
