Nope haven't done any fixs yet. But I haven't been doing any sawing either, as I'm done in Turlock Cal. making Bee Hive splits. Should bee back to sawing by next weekend. Though it might bee awhilely until I can send it in as I have some saw jobs when I get back. Yeah if running it like it is will ruin it, I've been ruinning it for 2 or 3 years now. I will get it hammered after my next job though to be on the safe side.
