      If your Hilti Drill or its battery is getting very warm, immediately switch off the power tool, remove the battery, keep it under observation, and allow it to cool down. This could be due to an electrical fault or because the tool is overloaded. If it's overloaded, select a suitable power tool for the application.

      If the control switch on your Hilti Drill is stuck, it's likely because the forward/reverse switch is in the middle position. Simply push the forward/reverse switch to the left or right to resolve this.

      Your Hilti Power Screwdriver might not be working because the battery isn't fully inserted. Make sure to push the battery in until you hear a click. Alternatively, the battery might be low, so try changing it and charging the empty one.
