Actually, Hi-Lo trailers, particularly later models, really didn't change very much, and the manuals have always been somewhat generic. Our 2704T is virtually identical to a new 2709T we inspected at a dealership.
If you look under Hi-Lo manuals in this HTF, you'll find a 2008 Hi-Lo Operators Manual that covers all the models manufactured that year. I'm certain that this manual will probably answer all your questions regarding your 2806C, and is most likely the same manual (dates changed) that originally came with your Hi-Lo.
If the manual, because of its generic nature, still does not satisfy all your questions (and most likely it won't), ask the members of this Forum. We are very generous with answers to good Hi-Lo questions!
By the way, welcome to the Forum!
Jim
