Or you could take it in for warranty. But they'll charge you $35(refundable if they decide it is a defect).
And they'll ask you a bunch of stupid questions to try and pin the blame on you.
I know this because I called to ask if the chain catcher on my 361P, which is made of plastic, and broke the first time I threw a chain, was a warranty item.
The guy asked me how it broke, and I told him I threw a chain when I was cutting some brush. And he said, "You were cutting brush!?", as though I had committed a crime.
And then tried to tell me that I had the chain too loose, and asked how tight it was(of course when I picked it up from them they had the chain so tight it couldn't be turned by hand, and would probably burn a bearing or otherwise destroy the saw if ran like that all the time). I told him my chain is always properly tensioned.
And then he proceeded to lecture me on the reason my chain got tore up was because I was cutting dirt and rocks. And I said there's nothing wrong with the chain, it's the chain catcher, after which he returned to lecturing me about how I tore up the chain, and I asked, "do you know what a chain catcher is?"
And he said something else about the chain and I said, "chain catcher, chain catcher"
And then he asked, "what is it was called again?"
After he looked it up, he said,"Oh guys usually just buy those"
And I said I'll buy one, and bring the broken part up there so it can be warranteed and I'll have an extra.
And he said that I'd have to leave the saw there so they could determine what caused it(cheap plastic chain catcher) to break.
Now I'm not bashing the dealer, because I'm sure the guy that owns the place and probably at least one other employee know what's what.
But there might be a few people that work at these places that could use some additional training.
