Hi, and welcome to our little corner of the 'net.
As others have pointed out, the router you purchased is old, and, by todays standards, vastly outdated. However, that DOES NOT mean that it is not a useful tool. A lot of us started out with a very similar machine. Some, like me, still have and use one.
Stick provided you with a LOT of reading material... take the time to peruse them. A router is a great tool, but it can also take your fingers off if used wrong. No loose clothing, no hanging jewelry or rings. If you have long hair, control it somehow so it doesn't hang down near the spinning bit. And, NO GLOVES! People sometimes wear gloves to protect their hands.. not when using a router, or any other power tool for that matter. The bit can catch the glove and pull your hand in before you know it.
One other thing, Stick posted some information about guide bushings... for your router, you will have to go to Sears for any guide bushings. If they are still available, they are a unique size and the more common sized ones won't fit.
Sometimes I wonder whether the world is being run by smart people who are putting us on
or by imbeciles who really mean it.
