A power door system for actuating door panels between closed and opened positions. An operator arm telescopically supports a push rod. A housing is secured to the operator arm. A spring pin extends through apertures in the arm and the push rod. A release cable extends from the housing and is movable to retract the pin, permitting inter-telescoping motion of the push rod relative the operator arm, in turn permitting manual displacement of the doors. A compression spring supported within the housing influences the pin into engagement with the operator arm and push rod. A locking pin and guide is incorporated into a cable mounting guard below the spring pin, the locking pin displacing with the spring pin to a retracted position in response to actuation of the release cable, a successive actuation of the release cable releasing the spring pin and lock pin to reengage the apertures in the arm and the push rod.
