STIHL MS 261 C-M 16″ Chainsaw

Why buy the STIHL MS 261 C-M 16″ Chainsaw? Powerful 50.2 cm³ (3.0 kW) STIHL 2-MIX petrol engine for professional use. Fitted with a 16″ (40 cm) Light 04 guide bar and .325″ RS Pro saw chain. M-Tronic technology for consistently optimal engine performance. Advanced anti-vibration system significantly reduces fatigue during prolonged use. Long-life air filter system with HD2 filter for extended service intervals. Features side-mounted chain tensioning and captive nuts for easy maintenance. The STIHL MS 261 C-M petrol chainsaw is a formidable tool engineered for professionals undertaking small to medium tree maintenance and forestry work. This updated model comes equipped with a newly designed 16-inch Light 04 guide bar and the innovative .325” RS Pro saw chain, a combination that boosts cutting performance by up to 20% compared to its predecessor due to a narrower kerf. This results in faster, more efficient cutting with less effort. At its core is a powerful yet efficient 2-MIX engine, delivering plenty of power while reducing fuel consumption by up to 20% and emissions by up to 50% compared to equivalent STIHL two-stroke engines without this technology. The saw’s intelligence is showcased by the M-Tronic system, which electronically controls the fuel and air mixture at all times, adapting to environmental conditions to ensure the engine is always operating at peak performance. For the operator, the STIHL anti-vibration system is a crucial feature, significantly reducing vibrations at the handles to allow for comfortable, sustained use throughout a demanding working day. Advanced Features for Professional Performance The MS 261 C-M is packed with features designed for convenience and longevity. The long-life air filter system with pre-separation routing and an easy-clean HD2 filter protects the engine from fine dust, extending its service life and maintenance intervals. A compensator in the carburettor ensures engine performance remains constant, even as the air filter begins to clog. User-friendly elements include side-mounted chain tensioning for safe adjustments, captive nuts on the sprocket cover that cannot be lost, and tool-free fuel caps for quick and easy refilling. The controlled-delivery oil pump allows the user to adjust chain lubrication based on the cutting attachment length or wood type, reducing oil consumption by up to 50%. Engineered for Reliability and Ease of Use Starting the MS 261 C-M is made easier with a decompression valve, which reduces the pulling force required on the starter cord. The combi lever with a stop function simplifies operation, as the control lever automatically returns to the operating position after being turned off, making warm starts immediate. For use in colder climates, the carburettor preheating system prevents icing, ensuring reliable operation even in winter. These thoughtful design elements make the MS 261 C-M a well-balanced, reliable, and powerful professional chainsaw for demanding forestry applications.
