The RANS Owners Bike Manual has general and specific information about all current models. Some of the info will relate to your bike. Try again for a download.
My 2000 Tailwind doesn't have the pivoting stem/riser. Someone else will have to provide info about that.
General maintenance issues are the same as with upright bikes except you have a much loooonger chain to maintain and, of course, the bars/stem/riser and seat are quite different. Keep an eye on whether or not your seat will maintain it's horizontal position. If not, info on how to deal with that is on the RANS site.
I've had good luck getting responses to questions emailed to RANS. Their website has lots of information but is amazingly slow.
Try Googling RANS Rocket for images and information.
