I should also add that the kickout of Liftall system is designed to protect the live pump and driving components. When it is locked open with the rotating lock tang, there is some possibility that those pump components and gear train could be stressed with an overload such as a deadhead when the hydraulic cylinder reaches the end of its stroke.
