Dependable cutting power comes from the Blue Max electric chainsaw. The electric motor creates a 37.7 ft. per second chain speed and 5500 RPMs. For safety, the mechanical brake system stops the chain from moving within 0.1 sec. It includes a safety pressure bypass valve with manual override, an auto lubrication oil system with oil level window for easy viewing and less maintenance. Make adjustments easily with the steel gear construction with a toothless chain tensioner.
