How to Set Depth Gauges
After filing or grinding, check and adjust depth gauges – depth
gauges control the “bite” of your saw chain.
Using the correct depth gauge tool for your saw chain:
1. Place the tool on top of your saw chain so one depth gauge
protrudes through the slot of the tool.
2. If the depth gauge extends above the slot, file it down with a
flat file, filing from the inside of the cutter to the outside so
that it is level with the depth gauge tool.

3. Never exceed recommended specifications. Doing so will
negatively affect the life of operation and increase the
potential for a chain shot event.
