Why Stihl Lawn Mower won't start?
- C
  christianadrienneNov 23, 2025
  Your Stihl Lawn Mower might not start due to several reasons: * There may be no electrical contact between the power tool and battery. Remove the battery, visually check the contacts, and refit the battery. * The battery may have a low charge (1 LED on the battery flashes green). Charge the battery. * The battery may be too hot or too cold (1 LED on the battery glows red). Allow the battery to cool down or warm up slowly at a temperature of about +15 °C to +20 °C. * There may be moisture in the power tool or battery. Allow the power tool and battery to dry. * There could be a fault in the battery (4 LEDs on the battery flash red). Take the battery out and refit it. If the LEDs continue to flash, the battery has a malfunction and needs replacement. * The power tool might be too...

Why Stihl Blower runtime is too short?
- W
  William WhiteAug 27, 2025
  A Stihl Blower's short runtime can be attributed to: * The battery not being fully charged. Charge the battery. * The battery's useful life being reached or exceeded. Check the battery and replace it if necessary. * The sweeping height being set too low, causing the side broom contact pressure to be too high. Adjust the sweeping height to suit the surface being cleaned.

What to do if Stihl Blower cuts out during operation?

  Scott MarshallAug 27, 2025
  If your Stihl Blower cuts out during operation, it could be due to the following reasons: * The battery or machine's electronics are too hot. Remove the battery and allow both the battery and machine to cool down. * There is an electrical or electromagnetic malfunction. Remove the battery and refit it. * The thermal overload cutout has tripped because the brush contact pressure is too high. Adjust the brush contact pressure to suit the surface being cleaned and wait about 30 seconds for the overload cutout to cool down. * The thermal overload cutout has tripped because the side broom or roller brush is blocked. Remove the blockage and wait about 30 seconds for the overload cutout to cool down. If the roller brush is blocked, press the switch to reset the overload cutout.

What to do if Stihl Blower battery is not being charged even though LED on charger glows green?
- F
  fosterpaigeAug 28, 2025
  If the LED on the charger glows green but the battery isn't charging, the battery may be too hot or too cold (1 LED on the battery glows red). Allow the battery to cool down or warm up slowly at a temperature of about +15°C to +20°C. Only operate the charger in closed, dry rooms at ambient temperatures between +5°C and +40°C.

What to do if light emitting diode on Stihl KGA 770 charger flashes red?
- A
  Andrea DavidSep 18, 2025
  If the light emitting diode on the charger of your Stihl Floor Machine flashes red, it could be due to a few reasons. There might be no electrical contact between the charger and battery (remove and refit the battery). It's also possible that there's a fault in the battery (remove the battery from the power tool and refit it; if the light emitting diodes still flash, the battery is faulty and must be replaced). Finally, there could be a fault in the charger itself (have the charger checked by a servicing dealer).

Why is my Stihl Floor Machine difficult to push?
- M
  Mark SotoSep 16, 2025
  If your Stihl Floor Machine is difficult to push, it may be because the side broom or roller brush is blocked (remove the blockage). It could also be due to the wrong sweeping pressure setting (adjust the sweeping pressure to suit the surface). Another cause may be that the gearbox components do not run freely (spray them with STIHL silicon spray).

Why Stihl KGA 770 Floor Machine running time is too short?
- S
  Stephanie SchmidtSep 16, 2025
  If the running time of your Stihl Floor Machine is too short, the battery may not be fully charged (charge the battery). It's also possible that the battery's useful life has been reached or exceeded (check and replace the battery). Another reason could be that the height setting is too low, causing the side broom contact pressure to be too high (adjust the height to suit the surface being cleaned).
