    What to do if Hilti TE 800 Power Tool doesn’t start and the service indicator lights red?

      If your Hilti Power Tool doesn't start, and the service indicator light is red, it could be due to worn carbon brushes. In this case, have the parts checked by a trained electrical specialist and replaced if necessary. Another possibility is a fault within the tool itself, which requires repair by Hilti Service.

    Why won't my Hilti Power Hammer start?

      Your Hilti Power Hammer might not start for several reasons. It could be due to electronics initialization or the activation of the electronic restart safety interlock after a power interruption. Try switching the power tool off and then on again. Alternatively, there may be an interruption in the electric supply; test another appliance in the same outlet. The supply cord, plug, or control switch could be defective, requiring inspection and potential replacement by a trained electrical specialist. If you are using a generator, it might be in sleep mode; apply a load by connecting another power consumer, such as a work light.

    Why is my Hilti Power Hammer not achieving full power?
    • E
      Emily KingAug 8, 2025
      Your Hilti Power Hammer may not be achieving full power due to several reasons. Power reduction might be active; try pressing the power level selector switch and restarting the tool. The extension cord could be too long or have an inadequate gauge; use a suitable extension cord (1.5 mm² for lengths up to 40 m; 2.5 mm² for lengths up to 65 m). Finally, the voltage provided by the electric supply might be too low; connect the power tool to a different electric supply.

    How to fix no hammering action on a Hilti Power Hammer?
    • A
      Angela BoydAug 17, 2025
      If your Hilti Power Hammer has no hammering action, it could be because the power tool is too cold. Try bringing the tip of the drill bit or chisel into contact with the workpiece and allow the power tool to run under no load until it reaches the minimum operating temperature. If this doesn't resolve the issue, there may be a fault within the tool that requires repair by Hilti Service.
