I've had this occur on a few of those guides I'll call them, then while fixing one of these, dropped the bar nose first into the dirt, that was fun to clean the bar sprocket & ball bearings 100%. Soaked, blew out with air, still grit, repeat, repeat repeat, LOL. I did what you are doing, took the burrs off and made sure all the works were smooth. Only time I've tossed a chain is when I hit a sapling and it gets caught, seems like it does this only when the cutters are dull, and the chain too slack, so I do an accurate sharpen with the MFR's guide clamp on bar guide, I compared results with my friend who has an almost identical Stihl as mine, he was sharpening the cutters with a dremel with a guide, in my opinion after sharpening his with the bar clamp guide, his dremel guide was inaccurate or it was just him, as the cutters were not as easy to sharpen as mine, it took a lot longer to get them like mine, his saw was new as well as mine, so he did not ruin the cutters I straightened them out and he said there was a big improvement in performance. He won't use the dremel anymore. I read the manuals and took it literally, then did my best to teach myself how to do what they instruct,without being ridiculous, the manual certainly was stringent, took me awhile to absorb the process. I don't think its all that bad to do it with this guide and a file, I get an accurate sharpen, in 1/2 hour. I also bought the $15.00 field sharpen kit with the file holders and the depth gauge, the clamp on guide was $100.00 and not machinist quality but seems to do the job. They say the accuracy of the sharpen and the uniformity of the cutters, the depth of cut plays a role in performance, I am by no means an expert, but I do know that a dull saw or improperly tensioned chain etc. etc. increases the danger factor. Last time I tossed a chain, it hit that aluminum catch under the cover, I think that is there to help absorb some of the energy, I've never tossed one at a high speed, always when cutting slow. i think that catch is important safety device that needs to be replaced after it's been used, not sure though. One thing I also don't know is what proper chain tension should be, I keep mine taut, but with some slack on the bottom, and I keep the oiler on max. Someone will hopefully add to this, and I may stand corrected, no expert, just sharing some of my experiences with it. I do however respect these things, they have no conscience !
