Took the 661 cover off to do some basic cleaning after bucking some 39" hackberry logs the other day. I found this gouge. I don't remember any problems while cutting. Undetected loose chain?
New saw, maybe 6 tanks of fuel through it so I wouldn't think so. But just a minute and I'll pull the cover again and check it.
Just grabbing at straws. Curious as to how it got on a bind myself. This happened once on my old Echo CS3400 and I could never figure what caused it.
Never came off but I'm thinking it was, at some point, loose. I always pull the cover and clean everything, remove the bar service it, blow out the aid filter, put it back together and sharpen the chain. You'd think I would bave seen it before today. Oh well, I'll start paying mode attention to chain tention.
Have you checked the condition of the driver links on your chain(s)? Do you think they could have beat up the cover like that, if the chain had loosened up?
