Maintenance (cont’d)
Filing Depth Gauges
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. Refer to Figure 22. 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.

Refer to Figure 25. Guide the file at a 10° angle to the
cutters.

3. Refer to Figure 26. File the cutters on one side of the
saw chain from the inside out. File on the forward
stroke only.
Figure 26 – Filing Cutters
4. Refer to Figure 23. Round off the front corner to
maintain the original shape of the depth gauge after
using the depth gauge tool. Always follow the
recommended depth gauge setting of the chain
manufacturer. This is important for maximum
perfor- mance throughout the saw chain’s life as
well as for protection against kickback.
