The STIHL MS 261 C-M is a high-performance professional chainsaw engineered for maximum power and efficiency. While it retains the robust features of the standard MS 261—including low exhaust emissions and high fuel economy—it adds the advanced STIHL M-Tronic engine management system. This onboard microprocessor digitally monitors and automatically adjusts for changes in elevation, temperature, fuel quality, and filter cleanliness, ensuring peak performance without manual adjustments.
Redesigned with a slimmer, ergonomic housing and updated cylinders, the MS 216 C-M boasts an impressive power-to-weight ratio. With a 50.2 cc engine delivering a formidable 4.0 bhp in a 10.8 lb powerhead, this saw is the go-to choice for professionals who demand consistent, hardworking performance across a wide range of cutting conditions.
Key Features & Benefits
Intelligent Technology
- STIHL M-Tronic: An intelligent engine management system that eliminates manual carburetor adjustments, compensating for environmental changes and fuel quality automatically.
- Pre-Separation Air Filtration System: Uses centrifugal force to eject heavier dirt particles before they reach the filter, doubling the time required between filter cleanings.
- Adjustable Automatic Oiler: Allows the operator to fine-tune the lubrication of the guide bar and chain based on bar length and specific cutting conditions.
Effortless Starting & Maintenance
- STIHL ElastoStart: A specialized starter handle with a built-in shock absorber that reduces the sudden peak forces felt during cranking for a smoother start.
- Decompression Valve: Vents compression in the cylinder during cranking to significantly reduce the effort needed to pull the starter rope.
- Toolless Fuel and Oil Caps: Features easy-to-lift levers for quick refueling and oiling by hand, with retainers to prevent cap loss.
- Side-Access Chain Tensioner: Conveniently adjust your chain tension with a bar wrench from the side of the housing, away from the sharp chain.
Professional Ergonomics & Safety
- Exceptional Power-to-Weight Ratio: Lightweight and maneuverable design reduces operator fatigue during long shifts without sacrificing professional-grade power.
- Anti-Vibration System: Specifically engineered to minimize vibration levels to the handles, providing a more comfortable and precise cutting experience.
- Ematic Lubrication System: When used with OILOMATIC saw chain, this system reduces bar oil consumption by up to 50% by directing lubrication exactly where it is needed.
- STIHL Quickstop: An essential safety brake designed to stop the chain rotation in fractions of a second in the event of a kickback.
