The document discusses when to sharpen the teeth on a chainsaw. It recommends sharpening the chain with a round file every time you refuel the saw, rather than waiting until sawdust starts coming out. Sharpening the chain regularly with only a few strokes each time helps maintain high performance by keeping the chain sharp, prevents underperformance and crooked cuts from a dull chain, and avoids needing to replace the chain too soon.
