Why won't my Hilti Impact Driver start?
- S
  Shirley MorrowJul 27, 2025
  If your Hilti Impact Driver doesn't start, it could be due to several reasons. It might be undergoing electronics initialization or the electronic restart safety interlock has been activated, so try switching the power tool off and then on again. Check for an interruption in the electric supply by plugging in another appliance to see if it works. The supply cord or plug could be defective, in which case you should have it checked and replaced by a trained electrical specialist. Alternatively, the control switch might be defective, requiring a check by a specialist and possible carbon brush replacement. If you're using a generator, it may be in sleep mode; apply a load by connecting another power consumer.

Why is there no hammering action on my Hilti Impact Driver?

  Wendy ThomasAug 11, 2025
  If you're not getting any hammering action from your Hilti Impact Driver, it could be due to a few reasons. The tool might be too cold; try bringing the tip of the drill bit or chisel into contact with the workpiece and let the tool run under no load until it warms up. There could be a fault in the tool, requiring repair by Hilti Service. Also, electronics initialization might be in progress or the electronic restart safety interlock may have been activated after a power interruption, so try switching the tool off and on again. Check for a power interruption by plugging in another appliance. Finally, the supply cord or plug could be defective and need to be checked by a trained electrical specialist.

How to increase the power on a Hilti Impact Driver?
- Q
  qthomasAug 19, 2025
  If your Hilti Impact Driver isn't achieving full power, it could be because power reduction is active. Try pressing the power level selector switch and then switch the power tool off and then on again. The extension cord might be too long or inadequate; use one with an adequate conductor cross section (1.5 mm² for lengths up to 40 m; 2.5 mm² for lengths up to 65 m). It’s also possible the voltage from the electric supply is too low, so try connecting the tool to a different supply.
