We have a 2000 310S and should have all the manuals for the unit, but they are in a binder which is in the camper that is in storage!
Yes, the plates get secured prior to putting the slide out. All is done in in reverse to bring the slide in. Going out the unit stops independently; coming back in you need to manually stop it when it is snug. We have only had the slide/unit leveled one time and will probably have the slide leveled at the end of this camping season as our left side has been a bit lower than the right side! Fortunately, we are only 40 minutes from Bellville, Ohio.
We are the original owners and have not had any issues with our HiLo. Actually, I am hoping to have the wheels repacked next week. We use all purpose grease on the lift mechanism and spray lithium grease on the cables and stabilizers.
Let me know what manuals you need and I will do my best to get the information to you. I know that the information is very similar to the tow-lite manual that has already been scanned into the library.
I was pleasantly surprised when I found this site about 1 1/2 weeks ago. I am happy to help!
Oh, one issue that we had. Our plug on the 30 ft cable was melted therefore we had to have the cord replaced…no fault of the trailer!
