Designed for the most demanding tree care and forestry professionals, the Stihl MS 400 C-M1 has a magnesium-alloy piston, a first in the chain-saw industry. This magnesium-alloy piston is designed to provide 13% greater displacement (compared to the Stihl MS 362 C-M), increased power and more torque, without adding weight. This chain saw also includes Stihl M-Tronic engine technology, designed to deliver low-emission, fuel-efficient performance under all operating conditions. Its lifetime HD2 air filter means you simply clean it instead of replacing it, while a pre-separation system is designed to remove large debris before it even gets to the air filter, thus increasing run time between cleanings. It is pictured here with an optional lightweight guide bar. (www.stihlusa.com)
