摘要： A hand-held power tool has an internal combustion engine provided with a throttle trigger adjustable between an idle position and a full throttle position. The engine has an operating mode selector adjustable between an operating position and a start position. In an intake passage of the engine, a throttle element is arranged that is in a throttling position when the operating mode selector is in the start position. The throttle element is secured in the throttling position by a locking action. The locking action is released when the throttle trigger is moved from the idle position toward the full throttle position. A restoring element is coupled permanently to the position of the throttle trigger. The restoring element, when the throttle trigger is moved for releasing the locking action, acts on the operating mode selector and restores the operating mode selector from the start position into the operating position.
