Description:

For greater maneuverability when felling large trees, turn to the impressive performance of the STIHL® MS 661 R C-M MAGNUM®. Its wrap-around handle provides greater operator comfort when cutting. Just like the MS 661 C-M, this saw includes STIHL M-Tronic™ engine management technology and delivers less vibration and 20% greater fuel efficiency than the previous model. This chainsaw boasts a long-life filtration system using HD2 filter elements to provide long run times between maintenance. Other features include an ElastoStart™ handle and a high-output adjustable oiler.

Wrap-handle version is available in select areas only.

Features:

• MS-Wrap Handle (R): Saw can be used in multiple positions for felling or limbing with hands in the proper positions.
• STIHL M-Tronic™: A new generation of intelligent engine management. Eliminates low and high-speed carburetor adjustment screws, while compensating for dirty air filters, elevation changes, and fuel quality—for optimum engine performance at all times.
• Ematic™ Lubrication System: When used with STIHL OILOMATIC® saw chain, this guide bar system provides proper lubrication with up to 50% less oil consumption. Ramps in the guide bar rail direct oil precisely where it’s needed.
• STIHL ElastoStart™: This exclusive starter handle includes a built-in shock absorber to reduce starting effort. It smooths out the compression forces felt during cranking for easier starts.
• IntelliCarb™ Compensating Carburetor: Automatically adjusts the air/fuel ratio to maintain correct RPM as the air filter becomes restricted. Uses clean-side air to regulate the fuel flow, unlike standard carburetors.
• STIHL Quickstop® Chain Brake: A chain-stopping system designed to reduce the risk of injury during kickback. Can be activated manually or by inertia, stopping the chain in fractions of a second.
• HD2 Air Filter: Washable filter with a large surface area for longer run times and excellent dust handling. Offers superior engine protection and reduced maintenance.
• Bumper Spikes: Provide better control and help prevent pull-in, making cutting easier and more precise.
• Adjustable Automatic Oiler: Lets you fine-tune bar and chain lubrication for varying bar lengths and cutting conditions.
• Decompression Valve: Vents compression in the cylinder to reduce starting effort. Opens manually and closes automatically when the engine fires.
• Lightweight Sprocket Cover with Captive Bar Nuts: Streamlines maintenance by keeping bar nuts secure and reducing overall weight.
• Side-Access Chain Tensioner: Makes chain adjustments more convenient using a bar wrench.
• Master Control Lever™: A single lever operates the choke, starting throttle lock, and on-off switch. Requires throttle trigger pull before engaging the choke.
• STIHL Anti-Vibration System: Designed to reduce operator fatigue and provide a more comfortable working experience by minimizing vibration levels.
• Toolless Fuel and Oil Caps with Retainers: No tools needed—simply lift the lever and twist to open or secure.
• Throttle Trigger Lockout: A safety mechanism requiring deliberate engagement before activating the throttle.
• Reduced-Emission Engine Technology — Caring for Nature: Products with the STIHL Inc. “Caring for Nature” seal produce zero or low exhaust emissions and meet or exceed EPA and/or CARB standards.
