2026 STIHL Chainsaws MS 661 C-M MAGNUM®

Information

2026 STIHL Chainsaws MS 661 C-M MAGNUM®

Suited for use with long guide bars, this fuel-efficient chainsaw was designed for the demanding professional.

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 previous model. 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.

Features may include:

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.
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.
Bumper Spikes
  • These spikes prevent pull-in and provide better control, making cutting easier.
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.
Ematic™ Lubrication System
  • The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.
