The MS 661 MAGNUM® professional chainsaw delivers the reliable power and rugged dependability you need for felling, de-limbing, and bucking large diameter trees. This chainsaw features a simple, proven, and non-electronic design. A fuel-efficient engine and low-maintenance air filtration system help keep operating costs low, while the STIHL anti-vibration management system reduces fatigue and improves handling when compared to the previous model, even when using long guide bars. The MS 661 MAGNUM® chainsaw is the perfect partner for forestry, municipal, and tree service professionals.
- Adjustable Automatic Oiler allows the user to adjust the lubricant of the guide bar and saw chain for different bar lengths and cutting conditions
- Anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience
- Bumper spikes prevent pull-in and provide better control
- Decompression valve reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope
- Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods
- HD2 air filter on this unit is washable, providing extremely long filter life and lowering maintenance costs
- IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct rpm
- Sprocket cover is lightweight and the captive bar nuts are held securely in place for efficient saw chain maintenance
- Saw can be used in multiple positions for felling or limbing with hands in the proper positions
- Master Control Lever™ is an easy-to-use single lever, operating the choke, starting throttle lock, and on-off switch
- “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions
- ElastoStart™ starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord
- Quickstop® chain brake is designed to stop the rotation of the chain if activated by the operator’s hand or by inertia if the saw kicks back with sufficient force
- Side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw
- Throttle Trigger Lockout safety feature must be depressed before the trigger can be activated
- Toolless fuel & oil caps w/ retainers
