How do I oil my paper shredder?

I have a Duratech Model #SH6010CP. When I received it, there was no instruction book included. It was a hand me down. The last shredder I had was a Fellows and it worked great for 10 years. Somehow I think the oil process gummed up the shredder and I don't want that to happen to his one. So far I love it.

Is there anything else I should know about the machine to keep it running properly.
