With improved fuel efficiency and a high-powered engine, the MS 311 minimizes downtime and maximizes output—so you can get the job done and enjoy your well-earned downtime.

Features:

• Powerful Low-Exhaust Emission Engine
• Reduces fuel consumption and operating costs while delivering the reliable power users expect for tough jobs.
• IntelliCarb™ Compensating Carburetor
• Automatically adjusts the air/fuel ratio when the air filter becomes restricted, maintaining proper engine RPM for consistent performance. IntelliCarb™ uses clean air from the filter’s intake side, unlike standard carburetors that rely on air from the dirty side.
• Bumper Spikes
• Provide better cutting control and reduce pull-in during operation, making the cutting process more efficient.
• Decompression Valve
• Temporarily reduces compression in the combustion chamber during starting, requiring less effort to pull the starter rope. The valve closes automatically once the engine fires.
• Toolless Fuel and Oil Caps with Retainers
• Quick and easy access for refueling and oiling—no tools needed. Integrated retainers help prevent cap loss.
• Pre-Separation Air Filtration System
• Increases filter efficiency and service life by ejecting heavier dirt particles before they reach the air filter, doubling the time between cleanings.
• Side-Access Chain Tensioner
• Allows for easier chain adjustments using a bar wrench, avoiding the typical guide bar location for tensioning.
• Anti-Vibration System
• Minimizes vibration levels to reduce operator fatigue and enhance comfort during extended use.
• Master Control Lever™
• A single, easy-to-use lever controls the choke, starting throttle lock, and on/off switch—streamlining operation.
• Throttle Trigger Interlock
• A built-in safety feature that must be engaged before the throttle can be activated.
• High-Tech Polymer Housings
• Lightweight, impact-resistant, and corrosion-resistant housings ensure long-lasting durability in rugged environments.
