Yea well it was a real greehorn mistake on my part and i was really embarassed. Here's what I remember.
We had a big ####ed-up shaped limb down on the ground. I was bucking it up with my MS-361 CQ. Note the "Q" in that model number, it's part of my story.
A good portion of this limb was well over my head, it was kind of a twisted mess. I reached down and back-chained a 2" offshoot that was digging into the dirt. Unbeknownst to me, that offshoot was holding this entire limb from rolling down into the flat position. Before I new what happened, I'm down on my hands and knees with my running 361 under my chest. That crap happens FAST bro.
The MS-361 C Q has a quick-stop beaver-tail safety on it. As soon as your hand comes off the handle, the chain brake kicks in. So when I went down on the saw, the chain was stopped. My left wrist, I believe, was damn close to the bar too.
Stupid, stupid mistake.
Back hurt a bit the next day.
The dude at the Stihl shop tried to talk me out of the quickstop model too...
