Frank R,
We have a 2406 T which would be identical to yours and I have never experienced the problem you've described. Could you narrow down the point of the tilt out where the 'snagging" was taking place? There may be some tell-tale scrapings on the outer shell to help you identify. Was it on the top or one of the sides?
I have two thoughts about this. If it were on the side; I have never investigated the fulcrum upon which the tilt out rests but could it be possible that the fulcrum may have become loose? Maybe it is on a threaded bolt and the lock nut or pin has worked loose?
If it is on the top, I remember reading in a past post somewhere the discussion was that once the top is raised, some of us let the hydraulic pressure off while others do not. If the snagging was on the top, it might be wise to not relieve the pressure until after positioning the tilt out and before bringing it in, raise the top that extra 1/4" again before doing so. As Jim L said in his post, you may need to tighten the cables some. I had one cable that was not even finger tight when I re-tensioned them. The lock nut had come loose allowing the adjustment nut to back off which caused the slack in the cable. I think that would be the first item you should check.
I would encourage you to read one of my previous posts and check your roof. We just got our Hi Lo last July and discovered some really bad spots on the metal roof. You can see what we discovered and the action taken here:
