Start with a no-holds-barred, bulletproof professional chain saw like the MS 441 C-M and add the versatility of a wrap-around handle. Now that’s innovation. STIHL engineers have combined the STIHL M-Tronic™ engine management system that intelligently manages the operating performance of the engine with a wrap handle to maximize operator comfort and productivity. In the field, the M-Tronic™ automatically and constantly adjusts the fuel-air mixture, maintaining maximum operating efficiency under varying conditions like altitude, outside temperature, a dirty air filter or poor fuel quality. The STIHL M-Tronic™ system compensates for these factors by replacing low and high-speed carburetor adjustment screws (old technology) with electronic monitoring of the engine’s performance and digitally optimizing the fuel/air mixture over the entire RPM range (new technology). This intelligent operating system also provides a simplified warm start procedure, and a decompression valve for easier starts. A highly versatile, state-of-the-industry saw for professional-level jobs, the innovations on the STIHL MS 441 C-M system work hard to make your toughest jobs easier.
Reduced-Emission Engine Technology - Caring for Nature The STIHL Inc.
“Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.
Pre-Separation Air Filtration System (Pictured)
This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.
The Winter/Summer Shutter allows the carburetor to operate at optimum temperature year-round and helps to prevent carburetor icing when working below 50F (10C).
