MS 400 C-M
This is the world's first powerful professional chainsaw with a lightweight magnesium piston.
Magnesium Alloy Piston
Excellent Power-to-Weight Ratio (12.8 lbs./5.4 bhp)
Modern Design
Lightweight (12.8 lbs.)
Designed for the most demanding tree care and forestry professionals, the STIHL MS 400 C-M is built with STIHL M-Tronic™ engine technology to deliver low exhaust 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.
