With reliable performance delivered from STIHL battery power, the MSA 220 C-B is the most powerful battery-powered chainsaw in the STIHL lineup. Capable of felling and limbing, this saw is also the first STIHL battery chainsaw with a 16 in. bar. Its durable construction and reliable performance make it a powerful addition to the professional arsenal. The Ematic guide bar, when used with STIHL Oilomatic saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.
