Put the depth-gauge guide on the chain so that it covers 2 teeth. The depth gauge will stick out of the hole in the middle of the guide.

5
Use a 6-inch flat file to level the depth gauge down to the top of the guide. Usually only a few strokes will do the job. Work from inside the teeth to outside. Move on to the next depth gauge and work your way around the chain.

6
Remove the guide. Go back along the chain and use the file to flatten the rounded top of each gauge. Just take the edge off with a few strokes, don't lessen the height.

7
Release the tension on the chain after the sharpening and readjust the chain to the proper tension for cutting.

Tips & Warnings
Protect your hands by wearing leather gloves. These are sharp cutting tools you're working with.
It's not necessary to sharpen depth gauges every time you sharpen the teeth. Sharpen the depth gauges after the teeth have been sharpened 4 times.
