A while ago I was able to find the Kwikee step manual online, the name is Kwikee #888 Electric Step Owner's Manual (1422279).
But today it's been renamed. I just found it on Lippert Industries website:
It's the one named:
"KwikeeŽ 22, 23, 24, 25, 26, 27, 28, 28A, 30, 31, 32, 33, 34, 35, 36, 38, 39, 40, 41 and Platinum Series Electric Step Owner's Manual (formerly #888 "
I haven't used the emergency switch behind the driver's seat, but I understand that it is to be used when the chassis battery is dead and won't start the engine. When the switch is pressed, it will use the house battery to start the engine.
When my awning is unrolled, I can see the I.D. sticker on the forward end of the large aluminum tube.
The manual I found online a while back is :
Dometic A&E Sunchaser 8500 9000
Currently this seems to be available at:
The current version says "Sunchaser II" but it looks close enough.
I hope this helps.
