The STIHL MS 400 C-M Petrol Chainsaw represents a significant leap in professional chainsaw technology, being the world’s first model to feature a lightweight magnesium piston. This innovative design provides greater displacement, power, and torque without increasing weight, resulting in an outstanding power-to-weight ratio that is highly valued by tree care and forestry professionals. It is engineered for the most demanding tasks, including felling, delimbing, and preparing wood in medium to high-density stands.

At the heart of the MS 400 C-M is the intelligent STIHL M-Tronic™ fully electronic engine management system. This technology automatically adjusts the fuel-air mixture to compensate for changing conditions like altitude, temperature, and fuel quality, ensuring consistently high engine performance and optimal acceleration. The robust 2-MIX engine contributes to lower fuel consumption and reduced exhaust emissions. Further enhancing its professional appeal are features like the long-life HD2 air filter and a pre-separation system that removes coarse debris, significantly extending filter service life. The effective anti-vibration system minimizes user fatigue during long operating periods, while captive bar nuts and tool-free fuel and oil caps add to the convenience and ease of maintenance.
