The powerful MS 400 C-M chainsaw is the world's first chainsaw with a magnesium piston. In conjunction with the consistent lightweight construction, this leads to an extremely low power-to-weight ratio of less than 1.45 kg / kW. Experience for the first time, the newly developed 67cm³ motor with an output of 4.0 kW.
A high-performance cutting machine with STIHL M-Tronic, the MS 400 C-M is easy to start and highly specc’d. The rapidly accelerating MS 400 C-M is completely in its element when felling, delimbing and processing medium sized wood.

STIHL M-Tronic (FT)
For a cold start, the STIHL M-Tronic only needs one start position on the combi-lever. After starting, you can immediately power up to full speed. The amount of fuel required is precisely calculated by the system and supplied as needed. Otherwise, start in position I as usual.
This air filter keeps even the finest dust away from the engine, ensuring a particularly long service life. Thanks to special material, the filter can be washed clean, for example with STIHL Varioclean and warm water.
The decompression valve is part of the easy start-system. The valve should be pressed before starting in order to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic, meaning that it must be pressed manually before starting, but then closes automatically.
STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle.
Side-mounted chain tensioning
The tensioning screw is located on the side of the chain saw through the sprocket cover. Chain side tensioning allows the saw chain to be retensioned effortlessly, avoiding any contact with the sharp chain.
Controlled-delivery oil pump
The exact chain oil output can be adjusted maunally for varying conditions, allowing for a reduction of up to 50%.
Tool free fuel caps
Special caps on the fuel and oil tanks are designed for easy opening and locking without the need for tools.
Pre-separation air filtration system
The innovative long-life air filter system greatly extends the service life of the filter. Air routing removes larger particles of dirt, meaning the actual filter has less to do. So the saw can be used for longer without having to clean the filter.
STIHL anti-vibration system
Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.
This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.
Captive bar nuts
Bar nuts held captive in the sprocket cover will not get lost when changing over the cutting attachment.
Advanced combustion technology
Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result: lower consumption and high torque across a broad rpm range.
Light-weight piston made out of magnesium. Excellent power-to-weight-ratio . High maximum speed. High durability.
The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption up to 50%.

When working at heights with chainsaws, flexibility, breathability, comfort and protection are essential. X-Flex pants combine ultralight, extremely breathable AVERTIC™ pro lite cut-protection - material developed exclusively for STIHL - and the latest in breathable and durable fabrics. This combination creates a market leading product that not only looks good, but keeps operators cool and protected. AS/NZS 4453.3:1997.
Do you question which lubricant is suitable for which cutting attachment, climate zone or type of wood? No need to puzzle over the answers with semi-synthetic STIHL chain lubricant. Our high-performance lubricant is extremely suitable for all moving saw chains. Well protected. STIHL chain lubricant effectively protects saw chains from wear. Thanks to its high temperature resistance, cutting attachments are optimally protected even from short-duration maximum thermal loads. Smoking is inhibited. Keeps on flowing. Even at temperatures down to -20° C, STIHL chain lubricant retains its outstanding flow properties. Selected additives prevent resinification of the cutting attachment and other treated parts. And you can start using the saw straight away, even after an extended idle period.
