STIHL M-Tronic™ Engine Management System

The M-Tronic™ system electronically controls the ignition timing and fuel metering in any operating condition, factoring in altitude and fuel quality.  Now available on the STIHL MS 441 C-M chain saw and the STIHL FS 460 C-EM brushcutter/clearing saw, 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 M-Tronic™ system electronically adjusts the fuel/air mixture in the carburetor for all operating conditions: start, idle, partial and full load. With the M-Tronic™ system always taking external conditions into account, you save time and money.

Continuous Engine Performance

The M-Tronic™ continuously monitors the operating conditions of your chain saw 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 M-Tronic™ system begins saving you time – and money!  M-Tronic™ remembers your last setting under the same external conditions and resets to it every time once the engine reaches full power.
