Good thread going here...another couple suggestions:
A. NEVER (read as never ever ever) touch the chain or try to remove an obstruction (like a piece of bark lodged between the clutch cover and sprocket) when the saw is running, even if the chain doesn't move at idle. I've been sorely tempted at times, and I can see others tempted too. Shut off the saw at the first sign of trouble.
B. Try not to cut alone, BUT keep bystanders/helpers at least eight feet away at all times, even if you bind your saw in a cut (do not have them assist!). I think I remember a guy here in Minnesota who recently and accidentally killed his helper/wife with a chainsaw (I don't know the details).
C. Do not start the saw if you are tired, drunk, angry, sad, or otherwise not fresh and focused. I have cut under all the scenarios above and almost paid dearly for it on multiple occasions. If I'm not up for it, the wood will patiently wait another day.
Sorry to be a worry wart on the discipline, but let's all keep the warm red stuff inside our bodies.
Happy cutting all. WINTER'S COMING
