Greenworks presents this 40-volt cordless Li-ion brushless chainsaw. It has a brushless motor that allows it to run for a longer time and offer more efficiency. Even though it is powerful, it does not vibrate as much. It is lightweight, as well, so you can work freely without making your arms and hands feel tired. This chainsaw from Greenworks has tool-less chain tensioning. It also comes with an automatic oiler, which allows the user to make quick adjustments. This feature helps increase chain lifespan, too. Greenworks cordless chainsaw is a battery-powered tool. However, it delivers power that is similar to other gas chainsaws you may have used in the past. That's quite impressive, especially with the brushless motor that enables automatic power tunings to get to an optimal level. The chainsaw runs for almost an hour, giving you sufficient time to finish your cutting tasks. Please note that this product is skin only. You may purchase a battery pack and charger separately from The Grit.
