Oh the wonderful world of a Stihl Clam shell. You'll love the plastic bearing cages. Just a heads up a parts cleaner will be your friend.
I don't understand how the chain can move when the brake is on the ones I have when there on you can't move the chain.
Thanks everyone! After reading everyone's take on the matter, I examined the log that the incident ocurred on. No foreign matter ( nail metal etc) was found in the log. Nor was there any residue of fuel and oil. Which there shouldn't be any. The log did have a decent size, burn pattern on it. Now before the incident, I had been cutting for at least 10 minutes. When I started the saw she cranked up after second pull and I released the brake like I always do and move the switch to idle, and started cutting. Had about five logs , 1' in diameter about 4'high I was cutting like butter. Never stopped or idled the saw because I had them lined up leaning against a stump. The log in question had a knot in it. She started the log smooth and boged for a five second period, then returned to normal, finished the log and died. The knot is a mother... I took my MS 250 to it on its branch side and was bogging her. Got the branch off ( branch fell apart in layers) and saw is fine . Not buying break theory for two reasons A)no such thing as being almost pregnant with these things ( four logs later the break mysteriously engages with me not hearing a click... right) and my recollection of clutch, break and break band condition, the clutch was burnt more then the other items so heat started there. So what happen? I dont really know i hope it doesnt happen again. If it does I gonna buy an ECHO. lol
Dont think he will warranty this if he does I will buy carbide chain from them. If not he doesn't get repair work I will get parts and fix it myself. Got the repair manual ... what the hell I rebuild engines this is walk in the park.

I agree with that analysis - a dull chain would put the heat into the clutch. Most people just don't realize just how sharp a chain really should be. Heck my Dad still doesn't get it and he showed me how to use a saw. Think of each cutter as a good wood chisel, that's how it should be sharpened.Sorry but I've been around long enough now to know, the stories most people tell are incomplete, or flat out lies.
Jim sorry but after reading your story it is very clear you did what most do. Saw won't cut, push harder. The burn pattern is from the friction a dull as hell chain creates. Not only will this heat burn the wood, but like you now know it will also overheat the saws metal components and melt the plastic ones. Take this as a learning experience and an opportunity to learn how to sharpen a chain. Remember the chain should throw chips not dust, the saw should self feed through the log, no pushing please.
Couldn't tell you how many times people have set a brand new saw down idling with the brake on. Only to find it "on fire" in a minute or two at idle.
So it's not good to idle with the break on? Frequently, when I'm not cutting, I engage the break as I walk through the woods or set the saw down for a minute. I guess I don't normally let it sit idling for long. If it won't be doing anything for a few minutes, I shut if off.

OK, now TWO posters on this thread are doing it.
When you are writing about a device designed to slow or stop mechanincal movement, it is a "brake". When you are taking a rest period at work, that is a "break". A day "breaks", as does a window or a water glass. You might "break" your saw if you abuse it, but if you click forward the safety handle in front of the handle bar on your saw, you have applied the chain "brake".
Before half of you jump to the defense of someone who wants to spell wrong (they can't help it, what difference does it make, this isn't school, blah blah blah) - I'm not criticizing anyone, but wrong is wrong. If you look closely, several other posters have tried to correct this too. :bang:
Feel better now?
I'd like to see the words break and brake used properly but if they're not I can usually muddle through.
If we made proper word usage, grammar, spelling and punctuation absolutely mandatory here we'd lose a lot of members. Not everyone has the ability to write and spell perfectly but they usually have valid questions and answers and they come here for help...not English lessons.
Lighten up.

I will try to lighten up, your points are well taken.
However, "Johnny can't read" coming out of high school because so many are willing to give him a pass when it comes to spelling and grammar (and math and science and history and personal finance, especially personal finance, and ... the list goes on and on).
My wife teaches at the college level. She finds more and more that many of these so-called "graduates" can't even function as literate adults. Their lack of knowledge about the basics of what's going on in the world around them is truly stunning. Don't get me started on the patently ridiculous and ignorant stuff I heard before the elections. I'm not talking about political views, I'm talking about a failure to understand the basics of how a presidential election works!!!!
When are we going to stop worrying about hurting a school child's self-esteem, and start acknowledging individual failure? Failure or, perphaps more imporatantly, a sense of failure can bring about great changes in an individual.
I realize this is a chainsaw forum and I am WAAAYYY off topic (my apologies to the OP for that), but I believe that proper writing is ALWAYS worthy of the effort - even here.
Rant mode off.
Blaze away at me if you want. Find some grammatical or spelling error in my post and go after me with it - whatever. Just be sure to spell and use the words correctly. Otherwise, you are proving my point.
