Oregon's high-power, 15 amp CS1500 chainsaw is the only electric chainsaw on the market with a chain that can sharpen itself. The CS1500 has all the traditional conveniences of an electric saw — instant start with the pull of a trigger, minimal maintenance, low noise and silent between cuts — and takes it one step further by incorporating the built-in PowerSharp® chain sharpening system. With a simple pull of the red PowerSharp® lever, you'll take your chain from dull to sharp in as little as 3 seconds so you'll never cut with a dull chain again.
