STIHL Magnum MS 661 C-M 20 In. 91.1 Cc Gas Chainsaw

When professionals need to fell large trees, in large quantities, they reach for the saw they know has the power to get the job done – the MS 661 C-M. Featuring an impressive power-to-weight ratio and STIHL M-Tronic engine management technology, the MS 661 C-M chainsaw also delivers less vibration and 20 percent greater fuel efficiency than the MS 660. Other features include a long-life filter system using HD-2 filter elements to provide longer run times between maintenance, an ElastoStart handle, and a high output adjustable oiler. (Wrap-handle version available in select areas.) See MS 661 R C-M.

Caring for Nature -Identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines low exhaust emissions as being cleaner than EPA and/or CARB exhaust emission standards.

Decompression Valve – Vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope.

STIHL M-Tronic – a new generation of Intelligent Engine Management that eliminates the low and high speed carburetor adjustment screws, compensates for dirty air filter and changes in elevation and fuel quality for optimum engine power at all times.

ElastoStart Starter Handle – A starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord.

Adjustable Automatic Oiler – The Adjustable Automatic Oiler allows the user to adjust the lubricant of the guide bar and saw chain for different bar lengths and cutting conditions.

Side-Access Chain Tensioner – The 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.

Anti-Vibration System – STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
