How to fit the diamond core bit into the chuck of my Hilti Tools?
If you can't fit the diamond core bit into the chuck, the core bit connection end or chuck might be dirty or damaged. Clean the connection end and/or the chuck, or replace these parts if necessary. Also, ensure that the chuck operating lever is fully open; open the lever as far as it will go.
What does it mean when the service indicator lights up on my Hilti Drill?
If the service indicator lights up on your Hilti Drill, it could mean that the carbon brush wear limit has almost been reached. In this case, have the carbon brushes replaced at the next opportunity. It can also mean that the carbon brushes have been changed and must be run in. Run in the carbon brushes by letting the machine run under no load for at least 1 minute without interruption.
What to do if the diamond core bit doesn’t rotate on my Hilti DD 30-W Drill?
If the diamond core bit doesn’t rotate on your Hilti Drill, it may be jammed in the base material. Ensure you guide the drilling machine in a straight line. To release it, disconnect the mains plug from the power outlet, grip the diamond core bit with a suitable open-end wrench close to the connection end, and rotate it.
Why does the diamond core bit have too much play in my Hilti Drill?
If the diamond core bit has too much play in your Hilti Drill, the connection end might be defective. Check it and replace it if necessary. Also, ensure that the chuck lever is closed.
What to do if the diamond core bit can’t be fitted into the chuck of my Hilti DD 30-W Drill?
If the diamond core bit can’t be fitted into the chuck of your Hilti Drill, the core bit connection end or chuck might be dirty or damaged. Clean the connection end and/or the chuck, or replace these parts if necessary. Also, make sure the chuck operating lever is fully open.
Why is the drilling speed decreasing on my Hilti Tools?
Several factors can cause a decrease in drilling speed. It could be due to reaching the maximum drilling depth, in which case you should remove the core and use a longer core bit. Alternatively, the core might be stuck in the diamond core bit, requiring you to remove it. Other potential causes include using the wrong core bit specification for the base material (select a more suitable one), high steel content (select a more suitable diamond core bit specification), a defective diamond core bit (check for damage and replace if necessary), a polished diamond core bit (sharpen it by drilling into a sharpening plate), or an incorrect water flow rate (adjust the water flow regulator). Finally, ensure the connection end is clean and the diamond core bit is correctly fitted.
Why is the drilling speed decreasing on my Hilti DD 30-W?
If the drilling speed of your Hilti Drill is decreasing, several factors could be at play. It might be that you've reached the maximum drilling depth, in which case you should remove the core and use a longer core bit. Alternatively, the core could be stuck in the diamond core bit, requiring its removal. The core bit specification might be wrong for the base material, so select a more suitable one. High steel content, a defective or polished diamond core bit, or incorrect water flow rate could also be the cause. Clean a dirty connection end, fit the diamond core bit correctly, and check the water supply and filter element.
Why does the diamond core bit have too much play in my Hilti Tools?
If the diamond core bit has too much play, the connection end may be defective. Check the connection end and replace it if necessary. Also, make sure that the chuck lever is closed completely.
What to do if water escapes from the chuck during operation of my Hilti Tools?
If water is escaping from the chuck during operation, it's likely that the core bit connection end or the chuck is dirty. Try cleaning the connection end or the chuck. If the problem persists, the chuck seal may be defective, requiring you to check the seal and replace it if necessary.
Why is the service indicator blinking on my Hilti Tools?
The service indicator may be blinking because the motor has overheated, possibly due to excessive lateral core bit friction or excessive contact pressure. To resolve this, wait a few minutes until the motor cools down, or allow the diamond core drilling machine to run under no load to speed up the cooling process. Switch the diamond core drilling machine off and then on again. Also, guide the diamond core drilling machine carefully, keeping it straight, and reduce the contact pressure.
