Professional climber here.
It was the 201 that only I use. The chain (new last spring) was sharp but if I cut through anything 6" or thicker it would start to get pinched. I always file down the burrs, so I know it wasn't that. Anyway, someone broke the chain on our other 201, so when the boss got a new chain I stole it for my saw and passed my chain down. Problem solved.
So even though the chain was sharp, and the bar is straight and free of burrs, it cut like garbage until I replaced the chain.
This problem is starting to show up again in some of our ground saws too.
My question is:
We've got some new guys on the crew who are green and eager. Is it possible that, when they try to sharpen the saws, they're ruining the chains irreparably? Maybe, somehow their angles are thinning the kerf or something. Never experienced this. Our foreman is confused too.
