My 709 paperwork says it will work, and its true to the extent that it can be if installed properly. The elongated holes are simply just barely long enough to allow it to be lifted to table height. Just FYI, the extension is fixed to the saw with bolts, so there's no taking it on an off depending on the need. Its a valuable tool but I can see how it would be difficult to use if you transported your saw a lot. At first, I thought it wouldn't work on my 709, but with a little more patience, I got it into place such that the plate is even with the saw turntable.
