What to do if the service indicator blinks red on my Hilti Power Tool?
- DDaniel PierceAug 20, 2025
If the service indicator on your Hilti Power Tool is blinking red, it could be due to a couple of reasons. One reason is that the overheating prevention cut-out has been activated. To address this, allow the tool to cool down and clean the air vents. Note that running under no load is still possible. Another reason might be that the voltage provided by the electric supply is too high. In this case, try using a different power outlet and check the electric supply.
