I think I understand the basics of using a file and guide to sharpen a chain but am having a problem with my new Stihl saw. I have the MS251 with .325 RM3 chain and decided to touch it up for the first time after bucking up a couple trees.
It seemed Ok sharpening the cutters from the left side, but it felt like the file kept hanging up as I sharpened from the right side. Of course I must have the angle wrong but I payed real close attention and don't see what I am doing wrong. The file seems to be binding slightly by making contact with the depth gauge as if I have too much of an angle on the file. But I am looking closely at the 30 degree etched line and it seems to bind when I do that. I have to reduce the angle a bit to get room to make a pass with the file.
My file is for .325 chain. I just don't feel like I got 3 good smooth passes or kept the right 30 degree angle for most of them.![Confused :confused: :confused:](/talk/styles/default/xenforo/smileys/confused.gif)
