Hi Steve and welcome. We have a number of Craftsman manuals in our manuals subforum. We may not have that specific one but there should be something close. If you click on the large Routerforums logo at the top of the page it will take you to the home page where you can scroll down until you find that section. Fixed base router manuals don't usually give very much info in them. What are you looking to find out? By the way, the 315. in the model number indicates that the machine was made by Ryobi.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
