Ken, I agree with LBS. If it is only happening only in "certain areas", you've got a chain problem, not a "machine problem. I'd look very, very closely at that chain, those drive sprokets and all the idler rollers. Now, it sounds to me like you are getting this symptom with no hay in the machine? Gotta remember that the chain will normally stretch with use. No big deal, the air bags will compensate for the lengthening of the chain. However, over time it will loosen to the point that it is just "too loose" when empty and the air bags just cannot take up all that slack. At this point, you've either got to replace that chain or take out a bar/links to shorten it. Take heed tho, while removing a bar will certainly give you a little more life out of that chain, you don't want to take the chance of it coming apart while in operation. When that chain decides to exit the machine on it's own, it isn't pretty. It usually takes everything in it's way with it, including the adjoing sheet metal, door hinges, axles, etc., etc. Keep at it; you'll get 'er. Allan
