Yes, that is one way to get a Schwintek in or out. But as always, you were told by someone that has NEVER attempted to do that. He was instructed or read about it, but has never done it. Yes, you can disengage the controller(I prefer to disconnect the 12 volt power which is easier). But it takes some mighty strong People(usually 3 or 4) to push the Scwhintek mechanism. The better way as long as the Red and Black motor wires are not damaged, is to put into OVERRIDE and then use the motors to bring it in or out. IF a motor is defective and stuck then you cannot push anyways. Always try the OVERRIDE method FIRST, then try the manual push in. Doug
