How do I put the cutting rollers back in ?

My son took my Aurora Paper Shredder apart because it wouldn't shred. It is a model AS662C. I have all the parts but I would like to get it put back together and don't know exactly where certain parts go without seeing a picture of it. I learn easily on how to fix things with seeing pictures. Is there any place where I might find out how to put it back together? If I could find a manual on this product it would help me out since I just bought it 2 months ago.
