While I've never had the need to adjust our slide, there is an Electric Slideout System Manual available at this Lippert website:
www.lci1.com
Once there, you can select which type of slideout system you have, download and print off the manual.
The manual contains photos of the various moving components as well as adjustment instructions.
Let us know if you went ahead, made any adjustments, and how they affected the operation. Its always good to get feedback on these types of DYI projects and if the manual was of any use to you.
Cheers
