Was bucking up a big downed oak for a friend yesterday, had a brand new chain on my 24" 6401, I mean a brand spanking new never touched a piece of wood chain. When I started the third cut the chain just wasn't cutting, I looked back at the second cut on the other side of the log and there's a small pile of ceramic tile fragments and I can see where I hit. I tried to touch it up with a file but it wasn't having it. Is there any hope for salvaging this chain? Should I aggressively file down the rakers?
