This saw’s advanced, high-efficiency brushless motor delivers the equivalent power of a 40CC petrol chainsaw that lasts up 130 cuts on a 4x4 (when used with the EGO 2.5Ah 56V ARC Lithium™ battery). The tool-less chain tensioning system allows for fast and easy bar and chain adjustments through independent dials, which are low profile in design and allow for cutting flush to the ground. The 20m/s chain speed allows for clean, efficient cutting and the automatic oiling system keeps the saw lubricated throughout the cutting application. For added control and safety, the saw is equipped with robust metal bucking spikes and kickback break with an easy to see brake position indicator. Experience Power Beyond Belief™ without the noise, fuss, or fumes.
