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 HD-2 filter elements to provide long run times between maintenance. Other features include an ElastoStart™ handle and a high output adjustable oiler.

Features:

• MS-Wrap Handle (R)
• Enables use in multiple positions for felling or limbing, ensuring hands remain in proper positions for safety and comfort.
• STIHL M-Tronic™
• Next-generation Intelligent Engine Management that eliminates carburetor adjustment screws, compensates for dirty air filters, elevation, and fuel quality, ensuring optimum engine power at all times.
• Ematic™ Lubrication System
• When paired with STIHL OILOMATIC® saw chain, the Ematic™ guide bar delivers precise lubrication, reducing oil consumption by up to 50%. Two ramps in the guide bar rail direct oil flow to key parts, ensuring efficiency.
• STIHL ElastoStart™
• A starter handle with built-in shock absorber that reduces pulling effort and smooths out peak forces felt during engine cranking.
• IntelliCarb™ Compensating Carburetor
• Automatically adjusts air/fuel ratio as the air filter becomes restricted, maintaining correct RPM for smooth operation.
• STIHL Quickstop®
• A chain brake system designed to stop chain rotation instantly when activated by the operator’s hand or inertia in a kickback, reducing injury risk.
• HD2 Air Filter
• Washable filter with a large surface area for longer filter life and better engine protection, especially in dusty or dry environments.
• Bumper Spikes
• Provide better control and prevent pull-in during cutting, making operations easier.
• Adjustable Automatic Oiler
• Allows users to adjust lubrication based on bar length and cutting conditions.
• Decompression Valve
• Temporarily reduces cylinder compression during starting, easing starter rope pull effort.
• Lightweight Sprocket Cover with Captive Bar Nuts
• Makes chain maintenance easier by securely holding bar nuts in place.
• Side-Access Chain Tensioner
• Conveniently adjusts chain tension with a bar wrench from the side, avoiding typical hard-to-reach spots.
• Master Control Lever™
• Single lever operation for choke, starting throttle lock, and on/off switch. Requires throttle trigger pull before moving to choke position.
• Anti-Vibration System
• Minimizes vibrations to reduce operator fatigue and enhance comfort during use.
• Toolless Fuel and Oil Caps with Retainers
• Easy to open or close caps without tools, secured with retainers to prevent loss.
• Throttle Trigger Lockout
• Safety feature requiring trigger depression before activation to prevent accidental throttle engagement.
