Try this link, it is for 2005 XCSP's but all of the information there would be the exact same for your 2004. It is the exact same manual on-line that I have for my 2005.

If this link doesn't work use my previous link and select 2005 / Owners / 2005 Edge snowmobiles with 121" track.
Enjoy the new sled.
