Steele Unveils Revolutionary Magnesium Alloy Piston
Like its predecessor, the MS 500i, which was the world’s first chainsaw with electronically controlled fuel injection, the STIHL MS 400 CM sets a new standard in chainsaw technology. This groundbreaking saw showcases a magnesium alloy piston, a revolutionary innovation that enhances power and torque without adding extra weight. With the integration of Stihl M-Tronic engine technology, tree care and forestry professionals can now enjoy a powerful chainsaw that delivers low emissions and improved fuel efficiency in any operating condition.
Notable Features: Engineering Excellence at Work
The word on the street is that the engineering team at STIHL has pulled off something extraordinary by replacing the standard aluminum pistons with magnesium alloy pistons. This ingenious move increases the engine displacement by a remarkable 13%, resulting in amplified power and torque. Despite the enhanced performance, with an impressive 5.4 horsepower, the STIHL MS 400 CM maintains an excellent power-to-weight ratio, weighing in at just 12.8 lbs.
Furthermore, the STIHL MS 400 CM is equipped with the M-Tronic intelligent engine management system. This cutting-edge innovation eliminates the need for low- and high-speed adjustment screws found in traditional carburetors. Instead, the system electronically adjusts the fuel and air mixture in the carburetor based on the prevailing conditions. This “smart” engine continuously monitors operating conditions and chain speed, optimizing engine performance while conserving fuel.
Thanks to the M-Tronic system, the STIHL MS 400 CM offers exceptional acceleration even after a cold start. It even memorizes the previous settings, allowing you to effortlessly resume operations under the same conditions every time the engine reaches full power.
Finally, let’s talk about the filtration system, another notable feature of the STIHL MS 400 CM. Starting with a pre-separation air filtration system, this chainsaw utilizes centrifugal force to remove heavier debris before it reaches the air filter, effectively doubling the time between cleanings. When it’s time to service the HD2 air filter, a simple cleaning will do instead of a complete replacement.
The STIHL MS 400 CM also boasts a range of other features, including:
- ElastoStart starter handles with built-in shock absorbers, reducing the force required to pull the saw.
- Quickstop chain brake, instantly stopping the chain in a fraction of a second during kickback.
- Adjustable auto lubricator, allowing you to adjust rod and chain lubricant based on rod length and cutting conditions.
- Ematic lubrication system, keeping rods, chains, rivets, and drive holes lubricated while reducing oil consumption by up to 50%.
- Anti-vibration system, effectively reducing operator fatigue.
- Fuel and oil cap retainer for convenient and secure use.
- Side entry chain tensioner for hassle-free adjustment.
- Master control lever, providing a single lever to operate choke, activate throttle lock, and switch.
- Pressure relief valve, facilitating easier starting by reducing compression in the combustion chamber.
- Winter/summer shutter, ensuring optimum carburetor temperature year-round and preventing freezing during cooler temperatures.
