I’ve heard of chains breaking but never experienced it until this morning. Was running my 390 with 24” bar and was cutting this little nub off when all of a sudden the entire chain was laying on the ground minus the part that got caught up by the chain brake. I must say, I do love the safety features of modern saws!
Been there, few years ago I just sharpened the chain on my husky 55 and went out to just wood. Just started on maybe the 5th cut and as soon as it started cutting the chain flew off and landed on the other side of the log, broke just like yours did. And I had no spare chain or back up saw that day
I did it once years ago with my old Poulan but that was before I knew much about saws and I had the chain adjusted way too tight.
I broke one last year, just finished sharpening the chain on the grinder, went into a big frozen log and it snapped half way through my 3rd cut maybe. Chain is still on the wall in the shop, still sharp as can be also.
Did you hit metal or anything to cause it or was the chain just not strong enough for the massive power of the Husqvarna 390?
I broke one with my stihl 390. Not sure what caused it. I don't remember if that one ever hit metal. I have cut railroad spikes with stihl chain and still had a lot of life left in it. Oregon/husqvarna chains are not as durable. One hit with those and they normally get retired. They also stretch a lot.
Maybe you can take it to someone with those chain makers and have them make it into a smaller chain for a different bar
I guess that if you counted the number of individual part's per drive link X the number of dl's and one of those many parts failed..... It's almost surprising that it's not more common. I don't have a chain in front of my right now, but looking at your pictures, are there 5 part's? Glad no one was hurt. The chain only looks like it's half worn.
Yikes! Ive thrown a chain plenty of times, but never had one break. Amazing how fast the brakes do engage. Sometimes it does and i dont even know it.
My thought too. I had a 22" chain shortend at OPE dealer. Cost me $5. Teeth had lots of meat left otherwise idve tossed it.
Can't tell in the pic, but take a good look at the tie straps and make sure they didn't get cut into during sharpening. I've had a few break over the years, the chain catcher on a saw is a good safety device for sure. They'll slap ya pretty hard, but never had one do any damage through the chaps.
I had one side of a chain break once. I noticed it was sitting funny. One side strap broke at a rivet. If I had a spinner/breaker, I'd have fixed it.
