Stihl MS 400 C-M Petrol Chainsaw
SKU: 1140 200 0475




The powerful MS 400 C-M Petrol 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.
The MS 400 C-M is a high-performance cutting machine with STIHL M-Tronic for flexible engine's ignition timing in all operating modes. This model also features the STIHL ElastoStart that helps reduce 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.
The innovative long-life air filter system greatly extends the service life of the filter. The air routing removes larger particles of dirt, meaning the actual filter has less to do. Therefore, the saw can be used for longer without having to clean the filter. Best of all, this chainsaw also comes with a comprehensive warranty for your peace of mind.
