MS 261 C-M
The same great MS 261, but with advanced STIHL M-Tronic™ technology for optimized performance in various conditions.
The MS 261 C-M has all the same great features as the MS 261 – low exhaust emissions, high fuel efficiency and robust performance – but also features the advanced STIHL M-Tronic™ engine management system. With STIHL M-Tronic™, an onboard microprocessor digitally monitors and automatically compensates for changes in your work conditions including elevation, temperature, fuel quality, varying octane levels and dirty air filters. The end result is maximum performance across a wide range of cutting conditions without making any manual adjustments. The MS 261 C-M also features redesigned cylinders and a slimmer, ergonomic housing for an impressive power-to-weight ratio.

Model Features
-
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.
-
Pre-Separation Air Filtration System
This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.

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.
-
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 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.
See it in action!
The STIHL M-Tronic™ engine management system electronically controls the ignition timing and fuel metering in any operating condition, factoring in altitude and fuel quality. This system provides professionals with optimum performance, whether you are just starting to work or resuming after a break.
Just Pull and Start
Thanks to the simplified warm start procedure, there is only one starting position on the combination lever.
No Manual Carburetor Settings
The STIHL M-Tronic system electronically adjusts the fuel/air mixture in the carburetor for all operating conditions: start, idle, partial and full load. With the STIHL M-Tronic system always taking external conditions into account, you save time and money.
Continuous Engine Performance
The STIHL M-Tronic continuously monitors the operating conditions of your chainsaw or brushcutter, calculating engine speed to continuously meter fuel. You save on fuel costs while experiencing optimum engine performance.
Excellent Acceleration
Thanks to the electronic ignition timing and fuel metering, you can quickly accelerate – even after a cold start.
Memory Function
From the second you start it, the built-in intelligence of the STIHL M-Tronic engine management system begins saving you time – and money! STIHL M-Tronic remembers your last setting under the same external conditions and resets to it every time once the engine reaches full power.
