Hello all. Tonight I was cutting a red oak with a very hard bark. When I was about half way through the tree which was about 3 inches, I noticed some sparks coming out of the tree. I backed off and tried it again at a different angle and not really sure what had happened. Any ideas possible? I have an 18 inch bar with a .325 chain if that means anything.
