1.
If the cutters are sharpened with a file holder, check and lower the depth gauges before sharpening the cutters.
2.
Check the depth gauges every third sharpening.
3.
Place the depth gauge tool on the cutter. If the depth gauge projects, file it level with the top of the tool. Always file from
the inside of the saw chain toward an outside cutter.

4.
Round off the front corner to maintain the original shape of the depth gauge after using the depth gauge tool. Always fol-
low the recommended depth gauge setting of the chain manufacturer. This is important for maximum performance
throughout the saw chain s life as well as for protection against kickback (Figure 15).
