Hey guys,
Recently purchased a new Stihl 26 RM3 chain for my MS-270. It's one of the green linked safety chains.
My first sharpening on the new chain with a 3\16" file that was mounted on a Stihl file guide and the file was not fitting down into the tooth for sharpening. The file was contacting both the tooth and the depth gauge. I ended up removing the file from the guide and then sharpening the chain. It felt like it'd take another sharpening or 2 to correct this. It ended up being my least sharp chain yet. I'm hoping it will widen enough for me to use it with my Granberg Bar-Mount sharpener.
Is this normal with a new chain? This is chain #3 for me and I don't remember having this issue before. Would you guys recommend filing the back of the depth gauge with the file held vertically and at 30 degrees?
