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% 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.
Features
- Reduced-Emission Engine Technology - Caring for Nature
- The STIHL Inc. Caring for Nature seal 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.
- This product features M-Tronic(M) - 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.
- The ElastoStart starter handle is an exclusive feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.
- 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.
- Simply lift the lever and twist the caps to remove or tighten. There‘s no need to use a tool to tighten or loosen.
- 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.
