Stihl MS 400 C-M Petrol Chainsaw
The Stihl MS 400 C-M petrol chainsaw is a high-performance professional-grade model designed for demanding forestry work. It delivers outstanding power, yet remains remarkably lightweight thanks to its advanced magnesium piston. The Stihl MS 400 C‑M petrol chainsaw offers an exceptional power-to-weight ratio, making it easier to handle during long hours of felling, delimbing, and pruning.
Magnesium Piston & M‑Tronic Engine Management
Equipped with a 66.8 cc engine producing 4.0 kW (5.4 hp), this saw features Stihl’s M‑Tronic 3.0 system, which automatically adjusts ignition and fuel delivery for consistent performance in all conditions. The magnesium piston reduces weight without sacrificing power, giving you greater efficiency and durability.
Long-Life Air Filtration & Easy Start
Its improved HD2 filter with pre-separation keeps larger debris out of the way, extending filter life and reducing maintenance. A decompression valve makes starting effortless, requiring less pull effort on the starter cord.
Precision Control & Comfort
The anti-vibration system minimises operator fatigue, while side-mounted chain tensioning allows safe, tool-required adjustments. With captive sprocket nuts, changing bars is hassle-free. Tool-free fuel and oil caps make topping up straightforward, and adjustable oil pump ensures precise lubrication.
Designed for Professional Use
At just 5.7 kg (powerhead only), the MS 400 C‑M is one of the lightest in its class. Despite this, it handles 16″–20″ guide bars and runs Ematic-bar-compatible chains for smooth, efficient cutting. Its steel claw bumper spike and durable design are perfect for forestry environments.
