Why light emitting diode on Stihl Trimmer charger flashes red?
- S
  Sydney YangSep 18, 2025
  If the light emitting diode on your charger flashes red, there might be no electrical contact between the charger and the battery. Try removing the battery and refitting it. Another possibility is a fault in the battery, indicated by 4 LEDs flashing red for about 5 seconds. In this case, take the battery out of the power tool and refit it. If the LEDs continue to flash, the battery has a malfunction and should be replaced. If the problem persists, there may be a fault in the charger itself, which should be checked by a servicing dealer.

  If your Stihl Trimmer battery isn't charging despite the charger's green light, the battery might be too hot or too cold, indicated by a red light. Allow it to reach a temperature between 15°C and 20°C. Also, make sure to use the charger indoors, in a dry place, and at an ambient temperature between +5°C and +40°C.

  Michael GibsonSep 15, 2025
  The running time of your Stihl Trimmer might be too short because the battery is not fully charged (charge the battery), you're using an unsuitable nylon line (replace the nylon line), or the battery's useful life has been reached (check and replace the battery).

  If your Stihl Trimmer battery isn't charging even when the light emitting diode on the charger glows green, the battery may be too hot or too cold (1 light emitting diode on the battery glows red). Allow the battery to cool down or warm up slowly at a temperature between 15°C and 20°C. Operate the charger indoors only in dry locations at an ambient temperature between +5°C and +40°C.

  If the battery is not being charged, even though the LED on the charger glows green, the battery may be too hot or too cold (indicated by one red LED glowing on the battery). Allow the battery to cool down or warm up slowly to a temperature between 15°C and 20°C. Operate the charger only in closed, dry rooms with ambient temperatures between +5°C and +40°C.

Why won't my Stihl FSA 65 Trimmer start?
- M
  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.

  Brian EwingAug 26, 2025
  If your Stihl Trimmer cuts out, it could be due to the battery or machine's electronics being too warm (remove the battery and allow both to cool down), or an electrical or electromagnetic fault (remove and refit the battery).

  If your Stihl Trimmer stops during use, it could be due to overheating of the battery or tool circuitry; remove the battery and allow both to cool down. Another potential cause is an electrical malfunction, which can sometimes be resolved by simply removing and reinserting the battery.
