Why won't my Stihl FSA 65 Trimmer start?

  Michael MurphyAug 23, 2025
  If your Stihl Trimmer does not start when switched on, several factors could be at play. First, check for electrical connectivity issues between the power tool and the battery by removing and refitting the battery. If the battery's charge is low (indicated by one green LED flashing), charge it. If the battery is too hot or cold (one red LED), allow it to reach an optimal temperature (around 15-20°C). For a faulty battery (four red LEDs flashing), replace it. Overheating of the power tool (three red LEDs) also prevents starting, so let it cool down. In case of electromagnetic issues or a machine fault (three red LEDs flashing), have the power tool checked by a servicing dealer. Lastly, ensure no moisture is present in the power tool or battery; if there is, allow them to dry.

  If your Stihl Trimmer isn't running as long as expected, the battery may not be fully charged, so ensure it's completely charged before use. The type of nylon line you're using could also affect runtime; consider replacing it with a more suitable line. Finally, the battery's lifespan might be diminished; check its condition and replace if necessary.

  A short runtime for your Stihl Trimmer may be due to the battery not being fully charged. Recharge the battery fully as described in the instruction manual for the STIHL AL 101, 300, 500 chargers. Alternatively, the battery's normal life may have been exceeded, indicating it's time to replace it.
