Product Information Very light, handy and powerful professional chain saw. The electronic self-tuning engine management system which means that the fuel supply is electronically controlled and the machine automatically adapts to operating and ambient conditions, ensuring optimal engine performance. Additional features include heated carburettor and handles, easy-clean HD2 filter, controlled-delivery oil pump and practical features such as a stainless steel muffler, captive nuts on the sprocket cover and monocoque cover with three quick release fasteners. The 2-MIX technology in the innovative STIHL MS 261 C-M VW ensures up to 20% less fuel consumption and up to 50% emissions reduction compared to the same power STIHL two-stroke engines without 2-MIX technology. STIHL is the only chain saw manufacturer in the world that develops its own saw chains and guide bars, so that the three components are guaranteed to match each other perfectly. All STIHL chain saws are manufactured with Swiss precision in the STIHL factory located in Wil, Switzerland. STIHL are made using special machines that have also been developed and manufactured by STIHL. STIHL chain saws not only deliver outstanding cutting performance on STIHL chain saws but are also excellent on chain saws from other manufacturers. Compact, powerful and fitted with the M-Tronic fully electronic engine management system as standard – the new range of STIHL chain saws deliver optimal engine performance at all times.

Key Features

* M-Tronic electric engine management – adjusts the ignition timing in all operating modes. M-Tronic continually monitors and electronically adjusts the fuel supply while the tool is in use. It even saves your previous settings and restores them when you next use the chain saw * HD2 filter - is made from polyethylene filter material with up to 70% finer pores than fleece and polyamide filters to trap even very fine dust. In addition, it is oil and water-repellent and thus very easy to clean. The PET-covered filter cartridge with quick-release lock enables the filter to be assembled and disassembled without using tools * Reduced-emission engine technology - 2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions * 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 * Pre-separation air filtration system - 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 * Anti-vibration system - the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles * Carburettor heating - by changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures * Heated handles - provide additional comfort in cold weather and can be engaged with a switch on the left handle as required * STIHL ElastoStart - reduces the shock caused by the compression of the engine during starting * Tool free filler caps - special catches on the fuel and oil tanks for easy opening and locking without the need for tools * Decompression valve - part of the easy starting system * 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 * Ematic chain lubrication system - ensures pinpoint lubrication of the saw chain links and guide bar rails providing 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% * 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
