I can't really answer your question as I've never had the opportunity to look at that model. Depending on the year and model, your unit may have one of the Schwintek powered slides. IIRC, they don't have the manual system you may be most familiar with. I think to retract or extend them manually, you have to physically disconnect the drive system (it isn't difficult) and at that point the slide becomes "freewheeling" and you just push it closed or open. Do a search for the Schintek slide system or go here:
Schwintek by Lippert
You should be able to find your version of Schwinteck (along with manuals) on the Lippert site, if that is what your unit has. Again, if IIRC, most of the newer Cruiser RV products have gone to the Schwintek slide systems.
Hope that gets you pointed in the right direction...
