MS 661 C-M

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.


STIHL M-TronicSTIHL M-Tronic™
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.
Decompression Valve Decompression Valve
 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.
STIHL ElastoStart STIHL ElastoStart™
 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.
Adjustable Automatic Oiler 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.
Oil Caps Toolless fuel and oil caps with retainers
 Simply lift the lever and twist the caps to remove or tighten. There‘s no need to use a tool  to tighten or loosen.
Chain Tensioner 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 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.
