Quoting Removed, click Modern View to seeTo your post of the other day regarding manuals, where you said you were not sure which ones to get. Go to
http://www.dmcretail.com/productSearch.aspx which is Case's site to order their Case Construction Equipment manuals. There you can do a search for your machine's manuals. If you don't want to buy a new manual from that site, record the manual part number you will see there and you can use that Case number as a reference to find the right manual on eBay or other sources. Check these for yourself, but it looks like the Service Manual for your 580CK is Case # 9-69650 and the Operator's Manual is # 9-1885. Hope this helps your get the right manuals.
