Juszt bought a used Ryobi AP10 Surface planer but there was no owners manual. I was able to find replacement blades and jig for replacing them at Amazon.com but they don't have an owners manual. I know the basics and can operate the planer but I will be changing blades soon and could use the help of the manual.My email address is terrymckee1@live.com if anyone can help. I've been looking on line but no luck yet. Thanks Terry
