From what I have read and heard about that model it was all positive as a good well built reliable chainsaw. I own the earlier version in both the 110 and 115 models. The only things that I seen not so great were they have problems with leaking bar oil from the molded fitting through the oil tank wall and that the AV mounts are a thin hollow rubber type that rot out frequently, first set went at around 12 years old , replaced them and they been ok since.Hey Jerry! You are pretty fluent in Dolmar.......what do you know about the PS540? Good saw??
