Two things I noticed that are odd. First, the instructions for lowering the bedplate/motor assembly show it being done with the wooden frame in place. There is not enough space beteen the frame and bedplate to do this without having to drop the bedplate into place the last few inches; I always remove my wood frame to remove and replace the bedplate.
The instructions for using the automatic stop mechanism imply that the stop can be moved in and out of position; mine doesn't not rotate on the handle shaft. In fact, in order to remove the bedplate, I have to completely remove the lift handle because the stop arm extends over the front of the bedplate.
