singer touchtronic grinding noise?

I recently purchased a Singer Touch-Tronic 2005 off Craigslist. It sews good but makes a grinding noise each time I use it. It didn't come with a manual or any instructions but I oiled and lubed it as much as I knew how. What could be the grinding noise and where can I get a manual for it?

Hello Anita,
It may be the gears which need to be checked, if you email me I can attach a list of sites for manuals, unfortunately this site has now stopped contributers posting their email address so you can get my address from any previous posting on this site or type this in at the end of my name not as you see it but as you read it.
