Although this thread is about a electric slide not a hydraulic one I could not find a forum on the Electric slide. The Service Manual for the Accu-slide (page 14) states that to open the slide manually use the Flexible shaft in your owner's packet. I do not have such a shaft and the service department of my RV Dealership appears to know nothing of this requirment. Does anybody have the flexible shaft? Did it come with the unit or was it obtained from the factory.
