We seem to be having problems with our lift (Tons of them). Our biggest problem now is that the propane regulator is starting to freexe up. By that I mean there is so much frost on the regulator and hose that you can bearly touch it. When this happens the truck won't idle and goes dead and doesn't want to start. Yesterday the operator put a lamp on the regulator and warmed it up then it started and ran fine all day until this morning. I tried changing propane cylinders but to no avail.

The regulator is not that old. They never had problems until a guy came and said we needed a regulator. As soon as he put it on it started freezing up all the time. Then it was fine for a couple of months. now it's starting to do it again.
To my knowledge this is all the info iv'e got (Just started here a few months ago). Does anybody have any suggestions for me? It's like pulling teeth to try to get any help on-line or over the phone. I would sure appreciate some feedback.
