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. See Figure 18. 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.
Figure 18 Lowering Depth Gauges
4. See Figure 19. Round off the front corner to main-
tain 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 per-
formance throughout the saw chain's life as well as
for protection against kickback.

of the saw chain. Reverse the procedure for the
other side.
4. Keep all cutters the same length.
5. File enough to remove any damage to the cutting
edges (side plate and top plate) of the cutter.
