15/16/18" Bar Supplied - 50.2 CM3 Displacement - 3.5BHP High performance mid-range option for the demanding farmer, gardener or landscaper. Versatile, durable 2.6kW petrol chainsaw. Economical 2-MIX engine cuts fuel consumption by up to 20% and emissions by up to 50% compared to conventional two-stroke engines. The MS 271 features STIHL's long-life air filter system with pre-separation and professional anti-vibration technology. Advanced combustion technology Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range. Anti-vibration system Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles. Pre-separation air filtration system STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct. Compensator This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs. Single-lever master control All important functions such as start, choke, throttle and stop are operated via a single lever. Side chain tensioner The tensioning screw can be found on the side of the chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain. Ematic chain lubrication system The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%. Tool free filler caps Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.
