This is a STIHL chainsaw model MS 362 / 362c / 400 c. World's first powerful professional chainsaw with a lightweight magnesium piston. Designed for the most demanding tree care and forestry professionals, the STIHL MS 400 C-M is built with STIHL M-TronicT engine technology to deliver low-emission, fuel-efficient performance even under changing conditions. Unlike its aluminum piston-equipped counterparts, the advanced magnesium piston in the MS 400 C-M provides greater displacement, power, and torque without additional weight.
A long-life HD2 air filter means you simply clean it instead of replacing it, while a pre-separation system removes large debris before it even gets to the air filter, increasing run time between cleanings.
