This fully electronic engine management system adjusts ignition timing and fuel metering in all operating modes. It also takes external conditions such as temperature, altitude and fuel quality into account. It ensures consistent engine performance, a constant maximum speed and superb acceleration. STIHL M-Tronic™ makes manual carburetor adjustments unnecessary. Thanks to electronic cold/warm start recognition, now there is only one start position on the Master Control Lever.

You need fewer pulls to start and can immediately accelerate up to speed - even after a cold start. STIHL M-Tronic™ also remembers the settings from the last time the tool was used. So when external conditions are the same, optimal engine performance is available every time you start up again. What else do you have to do? Fill up, start, and go to work. STIHL M-Tronic™ does everything else for you.
