Spoke with Paul today. They have sold 166 to date, 3 have been returned. One was over 200 hours run time, clutch side bearing failed and Husqvarna covered under warranty (aked him about fuel quality and he did not care, was would be covered unless straight gassed), second saws software went blank (Doug said he had only seen that on early 562's) re-flashed and is still ok, third saw was run over by a skidder and owner ate it. Did not understand your 75-80% failure rate and still do not. I call BS.
