Here at STIHL, we’re always trying to push the boundaries and bring new technology into the market. It could be with our battery-powered tools, injection chainsaws like the MS 500i or often, more subtle refinements to get more power out of established models, like the MS 151 T and MS 194 T. The new MS 400 C-M is another tool that pushes the boundaries of chainsaw technology – it’s the world’s first chainsaw with a magnesium piston, which means it has outstanding power to weight ratio!

The MS 400 C-M chainsaw has been designed with professional forestry and arb users in mind, offering STIHL’s highest performance and highest max rpm (14,000 rpm) in the 60cc chainsaw category. It also delivers a welcome increase in displacement, power and torque. 

ms 362 vs ms 400The new 2-MIX engine provides 4kW/5.4 hp, compared to 3.5kW/ 4.8 hp in the MS 362 C-M, as well as more torque – 4.1 newton metres (Nm) vs 3.5 Nm. These increases come from a large diameter piston and a 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, which means rapid acceleration for you! It’s also very durable too.

Thanks to these new materials and the same design features you see in the whole range of STIHL forestry chainsaws, 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 its own only weighs 5.8 kg too.

In addition to the new engine, the MS 400 C-M features the latest M-Tronic 3.0 electronic engine management system with the new and simple re-calibration process and an improved HD2 filter, so you get the best performance from the saw at all times. The chainsaw also features Elastostart technology so it’s incredibly easy to start each time. 

The MS 400 C-M chainsaw is available in 16”, 18” and 20” versions right now from your local STIHL approved Dealer.
