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. 4-3)
4) Round off front corner to maintain original
shape of depth gauge after using depth
gauge tool. Always follow the recommended
depth gauge setting found in the
maintenance or operator manual for your
saw. (Fig. 4-4)
