MS 400 C-M
The first chainsaw with a magnesium piston
General
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.

SynthPlus Chain Oil
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.
