Lubricating the Schwintek(Lippert) RV Slide out

Being new to Motor coaches, I have hard time trusting anyone to work on a complicated system. And I don't want to be down for 2 months.

I am a "preventative maintenance" type guy. The slide is expensive and complex mechanism to repair. I want to do all I can to prevent problems and keep the warranty in tact.

Does anybody out there lube their schwintex slide system? Can you provide any info, tips, tricks? Any tech's out there that can help me?

Thanks to all
