Get gas-like power without the drawbacks of gasoline. The 18 in. 15 Amp Electric Chainsaw is cost-effective, because you're not buying gas all the time. It's cleaner, both for the environment and your hands. And it starts much, much easier. Plus, it's outfitted with a whole host of high tech features to take the intimidation out of using a chainsaw. First off, it's only 11.2 lbs., so almost anyone can use and carry it around the yard. Auto-tightening and auto-lubrication systems take those normally laborious tasks and make them easy. Your chain will always be the right tension, without being too tight and will always stay well-oiled so it spins around the bar at an efficient 12 m/s. The chain pitch is 3/8 in., with 63 chain links and a gauge of 0.05 in. And the 200 mil oil tank has a handy oil-level indicator window, so you'll always know when you need to refill it. The metal bump spikes grab the wood, letting you get a solid hold on the log for a smooth continuous cut. That spike bumper also reduces kickbacks. The powerful 15 Amp motor provides consistent performance for years and easily tears through all common backyard chainsaw projects. The 18 in. bar is designed to take down standing trees with a diameter of up to 18 in. and can chop up a log on the ground twice that size.
