Give messicks a try they send me PDF files on the equipment they dont have online. They may have an owners manual available if you ask. I agree though the info contained in the operators manual is a CYA on their part. A good line of communication with your dealer will be far more rewarding in the long run.That because most machine the operators manual is just the companys "best wishes" so most people don't look for them much.
With Bobcat the service manuals contain all the owner manual stuff plus the service info, not sure if that is true for Case, but with bobcat the price is not much higher to get all the info.
I'm sure the dealers have them, not sure the $.
try www.tradebit.com or ebay
Good luck
