Why is the service indicator lighting up on my Hilti Drill?
- A
  aprilcabreraSep 16, 2025
  If the service indicator is lighting up on your Hilti Drill, it could mean a couple of things related to the carbon brushes. It's possible that the carbon brush wear limit has almost been reached, in which case you should have them replaced at the next opportunity. Alternatively, if the carbon brushes have recently been changed, they may need to be run in. To do this, let the machine run under no load for at least 1 minute without interruption.

What to do if the diamond core bit cannot be fitted into the chuck of my Hilti DD 150-U Drill?
- T
  Timothy MunozAug 25, 2025
  If you're having trouble fitting the diamond core bit into the chuck of your Hilti Drill, the issue might be that the core bit connection end or chuck is dirty or damaged. Try cleaning and greasing these parts. If that doesn't work, you may need to replace them.

What to do if the Hilti DD 150-U multifunction display is not showing anything?
- E
  Elizabeth ClarkAug 26, 2025
  If the multifunction display is not showing anything, there could be several reasons. First, check that the PRCD is functioning and switched on. Second, verify that there isn't an interruption in the electric supply by testing another electric tool or appliance, and inspect the plug connections, supply cord, power supply line, and main supply fuse. Finally, if there's water in the motor, allow the drill to dry out completely in a warm, dry place.

Why does my Hilti Drill show a restart interlock?
- J
  Joseph MacdonaldAug 27, 2025
  A restart interlock can occur for several reasons. The motor may have overheated, in which case you should switch the drill off and then on again. A supply network fault or power interruption could also be the cause; check other power consumers and the extension cord length, then switch the drill off and on again. Water in the motor or exceeding the maximum running time with hole-starting mode activated can also trigger this, so dry the drill or switch it off and on again, respectively. Overloading the drill can also cause this issue; avoid repeated disengagement of the slip clutch.

Why is the drilling progress slow on my Hilti DD 150-U Drill?
- M
  Michelle PorterSep 17, 2025
  A slow drilling progress on your Hilti Drill could be due to several water-related or mechanical issues. The water flow rate might be too high or too low; adjust the water flow regulator accordingly. Also, ensure the carriage lock is released. Finally, dust may be hindering progress, so use a suitable dust removal system.

Why is the drilling progress rate decreasing on my Hilti DD 150-U Drill?
- L
  Lisa MartinNov 27, 2025
  A decrease in drilling progress can be attributed to several factors. You may have reached the maximum drilling depth, in which case you should remove the core and use a core bit extension. The core could be stuck in the core bit, so remove it. The core bit specification might be wrong for the base material, so select a more suitable one. High steel content, a defective core bit, wrong gear selection, low contact pressure, insufficient machine power, a polished core bit, incorrect water flow rate, an engaged carriage lock, or dust hindering progress could also be the cause. Address each of these potential issues accordingly: select the right gear, increase contact pressure, select the next lower gear, sharpen the core bit, adjust the water flow rate, release the carriage lock, or use a sui...

Why does my Hilti Drill drilling system have too much play?
- M
  Michelle WoodSep 3, 2025
  Excessive play in the drilling system can stem from several issues. The core bit might not be securely tightened in the chuck; tighten it, remove it, rotate it approximately 90 degrees, and refit it. The core bit connection end or chuck could be defective, so check and replace them if necessary. Finally, the carriage might have too much play, requiring you to adjust the play between the rail and carriage.
