What is a depth gauge and why is it important?

• A. It measures chain tension
• B. It calibrates the bar length
• C. It sets the correct cutting depth of the chain to prevent overcutting and chain wear
• D. It starts the engine

Answer: (C)

The depth gauge sets how far each chain tooth can cut into the wood. It’s a small ramp or “raker” in front of the cutter on every drive link, and it limits the bite so the tooth doesn’t remove too much wood at once. Keeping this depth correct is essential for safe, efficient cutting and for reducing wear on the chain and bar. If the gauge is worn or set wrong, the chain can take too deep a bite, speeding wear and increasing the risk of kickback; if it’s set too shallow, cutting becomes harder and less efficient. When you sharpen the chain, you also restore the depth gauges so all teeth cut to the right depth. The depth gauge isn’t about chain tension, bar length, or starting the engine.
