Chainsaw Repair

If you take your chains to the chainsaw dealer, they all get ground at the same angles - 30 horizontal degrees on the top plate and 60 vertical degrees. No 10 degree droop on the chisel chains.

The Stihl chain angles in the chart usually represent the complement of the Oregon chain angles. However many of Oregon's angles say 55 degrees for the vertical angle though most people use 60 degrees.

I have a 511A and it grinds a Stihl chain just as well as it does Oregon chains. I do them at the same angles.
