Patent attributes
A power working machine has a machine body, trimming blades attached to the machine body and drivable by a drive source, an operating handle rotatably mounted on the machine body, a throttle lever disposed on the operating handle, and a throttle lock lever disposed on the operating handle for disabling pivotal movement of the throttle lever. The operating handle has a lock mechanism for locking the operating handle at a rotational position relative to the machine body, and an operation lever for unlocking the lock mechanism to thereby permit rotational movement of the operating handle and, simultaneously with the unlocking of the lock mechanism, for placing the throttle lock lever in a locking position to disable pivotal movement of the throttle lever. The throttle lock lever has a lock portion for permitting pivotal movement of the throttle lever while simultaneously locking the operation lever of the operating handle.
