Stihl MS400 C-M Professional Petrol Chainsaw

Stihl MS400 C-M Professional Petrol Chainsaw is the new Stihl Chainsaw, which is the world’s first chainsaw with a magnesium piston.

The MS 400 C-M chainsaw has been designed will professionals in mind, offering Stihl’s highest performance in the 60cc class. More displacement, more power, more torque, only a small weight increase compared to the MS 362 C M and an outstanding power to weight ratio.

The new 2 MIX engine provides 4kW of power, compared to 3.5kW in the MS 362 C M, as well as more torque 4.1 Nm vs 3.5 Nm. These increases come from larger displacement of 66.8cc, which is a 14% increase compared to the MS 362 C M. The magnesium piston is also 14% lighter than the aluminium piston in the MS 362 C M, helping ensure rapid acceleration.

Thanks to these intelligent design features, the MS 400 C M has an impressive power to weight ratio of 1.45 kilograms per kilowatt, making it ideal to use when working in the forest, especially over prolonged periods. The powerhead on it’s own weights 5.8 kg.

In addition to the new 66.8 cc engine, the MS 400 C-M features Stihl’s latest M Tronic 3.0 technology which has Stihl’s simple re calibration procedure and an improved HD2 filter, which all help deliver optimum performance from the saw at all times. The chainsaw also features Elastostart technology that enables effortless starting of the tool.
