Depth gauge tool vs eyeballing: Use a depth gauge tool, not your eyeballs

A dedicated depth gauge tool is the only reliable way to keep rakers consistent. Eyeballing leads to chains that either scrape or bog the engine and risk kickback. The tool ensures factory spec (0.025″–0.030″ below cutters) with flat, level strokes—no angling. A $10 guide tool saves your engine and chain.
