Stihl Chainsaw MS 271 The Stihl MS 271 wood boss® replaces the mighty MS 270 with a saw that’s loaded with features and technology. It starts with a highly efficient engine that delivers 20% longer run times between refuelings – while cutting exhaust emissions in half compared to the MS 270. There’s also a pre-separation air filtration system that’s so effective, your air filter can last up to five times longer (now that’s high performance). All engineered into one compact, ergonomic design. FEATURES 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. Anti-Vibration System STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience. IntelliCarb™ Compensating Carburetor The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box. Winter/Summer Shutter The Winter/Summer Shutter allows the carburetor to operate at optimum temperature year-round and helps to prevent carburetor icing when working below 50°F (10°C). Side-Access Chain Tensioner The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw. Master Control Lever™ The Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position.
