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. 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.
Lowering Depth Gauges
4. 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 performance throughout
the saw chain's life as well as for protection against
kickback.

2. Guide the file at a 10° angle to the cutters.
3. File the cutters on one side of the saw chain from
the inside out. File on the forward stroke only.
4. Keep the line on the file holder parallel to the center
of the saw chain. Reverse the procedure for the
other side.
5. Keep all cutters the same length.
6. File enough to remove any damage to the cutting
edges (side plate and top plate) of the cutter.
