ArboristSite Operative
I am probably too worried about this issue but I would love to hear comments. A month or so ago I bought an MS 440 from my local stihl dealer. Right after I made the buying decision the dealer showed me into his shop to fill up the saw with fuel and bar oil. Then he "showed me" how to operate the saw. To my horror he cranked up my brand new saw and "let her rip" wide open for a few minutes as he held the saw on the concrete floor. It scratched the paint off the handle at the bottom, no big deal, but it was brand new.
I kept my disgust silent. My main worry was that he was revving the pi$$ out of my cold new engine. I could just see the scoring eating up my new piston and cylinder. He went on to tell me that the only way to run chainsaws is to open the throttle wide open and not to baby it. I agree most of the time, but a saw should be warmed up before going balls to the wall.
I removed the muffler and inspected the brand new piston and cylinder. The piston (what I could see of it) looked fine with no signs of scoring, however the cylinder had streaks and most of the honing marks were gone.
