The STIHL MS 251 C-BE Chainsaw is as powerful and fuel-efficient as the MS 251, but is also easy to start and adjust. Ergonomically designed to bring you maximum comfort during use, this tool produces 50 percent less emissions (as compared to previous models) for a smaller impact on the environment. The MS 251 C-BE packs features like Easy2Start™ technology and easy-to-refill fuel and oil tanks, so you can worry less about starting and operating your equipment, and have more time getting your outdoor jobs done. And with its Quick Chain Adjuster, you can make sure you have proper tension on your saw chain without the need of additional tools. *A majority of STIHL gasoline-powered units sold in the United States are built in the United States from domestic and foreign parts and components.
