Thanks to the magnesium piston developed in-house by STIHL, the innovative STIHL MS 400 C-M gas chainsaw offers a range of advantages for forestry professionals. Thanks to the reduced weight of the piston and the lightweight overall construction, this chainsaw has a power-to-weight ratio of 1.45 kg/kW.

But when it comes to felling, delimbing and processing wood in medium-density forests, we know it is not just power that is important. That’s why the advanced version of the STIHL MS 400 C-M chainsaw is equipped with STIHL M-Tronic to enable you to work efficiently. This version also allows for calibration of the system. STIHL ElastoStart supports you when you start your chainsaw, making start-up particularly easy, while the STIHL anti-vibration system reduces vibrations to protect your muscles and joints,. The STIHL MS 400 C-M gas chainsaw features a long-life air filter system to ensure uninterrupted operation for as long as possible. This consists of a routing pre-separator and an HD2 filter.


    Features

    • Stihl M-Tronic: Reliable work with the best performance. With Stihl M-Tronic, you'll have the best performance from your work tool from the outset. Fully electronic engine management regulates the ignition timing and fuel metering in all work situations, taking into account external conditions such as temperature, altitude and fuel quality.
    • Stihl anti-vibration system: For more pleasant work. Vibrations can occur when you put your power tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the Stihl anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your power tool is more comfortable to hold and your work is much less tiring.
    • Manual decompression: Effortless start-up. The decompression valve makes it easier to start your power tool. When starting, you can allow some of the compressed mixture to escape from the cylinder by opening the valve. This protects the start-up system and reduces the amount of force required on the starter cord.
    • Long-life air filter system for chainsaws: Extended filter service life. Pre-separation routing removes coarse, larger particles from the airstream before they can reach the actual filter. The HD2 filter keeps even fine dust away from the engine, ensuring a long engine service life, long cleaning intervals and easy maintenance of your chainsaw. When we refer to a long-life air filter system in chainsaws, this exclusively describes models that have pre-separation routing and an HD2 filter. With this system, you benefit from a significantly longer filter service life compared to conventional air filter systems.
    • Controlled-delivery oil pump: The exact chain oil output can be adjusted manually for varying conditions, allowing for a reduction of up to 50%.
    • Stihl 2-Mix engine: Highly power-efficient. With the Stihl 2-Mix engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The Stihl 2-Mix engine complies with the strict EU Stage V emissions directive.
    • Stihl four-channel technology: For lower fuel consumption and high performance. Thanks to Stihl four-channel technology, you can work with your power tool with very low fuel consumption and high performance. The four overflow channels guide the fuel-and-air mixture into the cylinder in a targeted and more compressed manner, which optimally burns the fuel and significantly increases the performance of the engine.
    • Side-mounted chain tensioning: For simple and secure re-tensioning. Side-mounted chain tensioning allows for protected, easy and quick chain tensioning and replacement. The tensioning screw is inserted laterally through the sprocket cover.
    • Heated carburetor (V): For reliable operation even in winter. Thanks to carburetor preheating, you can work reliably with your chainsaw even in winter. You can change the operation from summer to winter mode in just one simple step. In the winter setting, pre-heated intake air flows around the carburetor, preventing it from icing up.
    • Tool-free fuel cap for oil and fuel tanks: Quick and easy to use. With tool-free fuel cap, you can open and close oil and fuel tanks in just a few simple steps, thanks to a bayonet closure.
    • Stihl Ematic system: Reduces oil consumption. The Stihl Ematic system comprises a Stihl Ematic or Ematic S guide bar, a Stihl Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.
