I bought my new MS271 Farm Boss in March 2016. I only used it for that one afternoon and the saw quit on me.
I took it into the dealer for repairs and they told me the same thing, I ran it too long w/ the chain brake on. I told them I had a much older Stihl Wood Boss and it would never allow me to rev up the engine and override the chain brake. I had a long running dispute going on w/ the dealer about the repairs. I had them repair it and it cost me $131!
So, I used it for about 1 week and then it totally quit on me again, chain is locked. That was in April 2016 and I've never taken it back. My concern is the next repairs will be almost as costly and approach what I paid for the chainsaw. So, I have never taken it back in again for repairs so it's just taking up space in my garage!!!
I finally contacted Stihl in Jun 2017 and the guy who replied to my complain tried to 'educate' on the difference between a clutch and chain brake.
Again, I told him the chain brake never failed me on my older Wood Boss and this seems to go in one ear and out the other. They never address why it was working on my Wood Boss and failed on the newer Farm Boss.
