Product Overview

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 and ElastoStart handle and a high output adjustable oiler.
  • Caring for nature seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions
  • Defines low exhaust emissions as being cleaner than epa and/or carb exhaust emission standards
  • The decompression valve, also referred to as 'deco' or 'deco 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
  • It is opened manually and closes automatically as soon as the engine fires
  • It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord
  • 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
