Hello -
I wouldn't bother calling Keystone customer service about obtaining instructions for the slide. It is my guess that the manual for that year is no longer available on their website for downloading. In addition, I doubt very much if anyone there will trouble shoot your issue with you over the phone. Who knows, you might get lucky and talk to a service tech but don't hold your breath.
If you have a Lippert slide out, I would phone them rather than Keystone.
Or, you can go to Lippert's website (
www.lci1.com) check for a manual there for downloading and printing.
