If you haven't found the manual yet you can try calling their parts service number at 888.873.3829. If they don't have it they might be able to direct you to the department that does.
I went to a garage sale today where a guy was selling his whole shop. I picked up an old craftsman dovetail template for cheap, but, didn't have the manual. Took me about 1/2 hour to find it on line. Not the greatest copy but I can read it enough to know how to put it together and make it work.
Good luck with your search.
