What to do if my Stihl FS 240 R Trimmer engine does not start?

  If your Stihl Trimmer engine won't start, it could be due to several reasons. First, ensure you have enough fuel mix in the tank; if not, refuel it. Another reason might be that the engine is flooded; try starting it with the choke lever in the appropriate position. Also, if the carburetor is too hot, allow the trimmer to cool down and depress the manual fuel pump at least 10 times before starting. Finally, the carburetor may have iced up, so allow the brushcutter to warm up to +10°C.

  If your Stihl Trimmer engine stops while idling, one potential cause is that the carburetor has iced up. To resolve this, allow the brushcutter to warm up to +10°C. Another possible cause is incorrect throttle cable adjustment, which requires adjusting the throttle cable.
