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 STIHL® 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 also features a long-life filtration system with HD-2 filter elements for extended run times between maintenance. Additional conveniences include an ElastoStart™ handle and a high-output adjustable oiler.

Features:

• MS-Wrap Handle (R): Allows the saw to be used in multiple positions for felling or limbing while keeping hands properly positioned.
• STIHL® M-Tronic™: A new generation of intelligent engine management that eliminates manual carburetor adjustments, while compensating for dirty air filters, elevation changes, and fuel quality to maintain optimum power at all times.
• Ematic™ Lubrication System: When paired with STIHL® OILOMATIC® saw chain, this system ensures precise lubrication and can reduce bar oil consumption by up to 50%.
• STIHL® ElastoStart™: A shock-absorbing starter grip that reduces the effort required to pull the starter cord by smoothing out compression peak forces.
• IntelliCarb™ Compensating Carburetor: Automatically adjusts the air/fuel ratio as the air filter becomes dirty, maintaining proper engine RPM for consistent performance.
• STIHL® Quickstop® Chain Brake: Designed to stop the chain within fractions of a second during certain kickback situations, reducing the risk of injury.
• HD2 Air Filter: Washable and built for extended service life, with superior dust protection and longer run times between cleanings.
• Bumper Spikes: Improve control and prevent pull-in, making cutting more efficient.
• Adjustable Automatic Oiler: Lets the operator control the oil flow for different bar lengths and cutting conditions.
• Decompression Valve: Temporarily reduces cylinder compression for easier starting with less pull force.
• Lightweight Sprocket Cover with Captive Bar Nuts: Provides easier chain maintenance while ensuring bar nuts stay securely in place.
• Side-Access Chain Tensioner: Conveniently located for quicker and easier chain adjustments.
• Master Control Lever™: A single, easy-to-use lever that operates the choke, starting throttle lock, and on/off switch.
• Anti-Vibration System: Reduces vibration levels, minimizing operator fatigue for more comfortable use.
• Toolless Fuel and Oil Caps with Retainers: Easy to open and close without tools, saving time during refueling.
• Throttle Trigger Lockout: A built-in safety feature that must be engaged before the throttle can be activated.
