Lowering depth gauges with a file

1) If you sharpen your cutters with a file holder, check and lower the depth.

2) Check depth gauges every third sharpening.

3) Place depth gauge tool on cutter. If depth gauge projects, file it level with the top of the tool. Always file from the inside of the chain toward an outside cutter. (Fig. 44)
