The MS 251 C-BE chainsaw is powered by the same large displacement engine as the MS 251 WOOD BOSS® with added comfort features like STIHL Easy2Start™. The STIHL MS 251 C-BE offers all of the comfort and ease of the MS 251 WOOD BOSS®, but this chainsaw is also easy to start and adjust on the fly. The MS 251 C-BE is perfect for felling small trees, pruning and thinning, and cutting firewood simply and efficiently. It even boasts up to a 20 percent fuel savings and a 50 percent reduction in exhaust emissions when compared to previous models—allowing you to enjoy longer run times while feeling good about your impact on the environment. A Quick Chain Adjuster also makes it simple to put the correct tension on the saw chain without tools. Plus, features like Easy2Start™ technology, a Master Control Lever™, and reduced vibration make the STIHL MS 251 C-BE a great choice for ambitious homeowners who need a chainsaw that is easy to use while still packing plenty of power.
