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 doesn't my Hilti DD 30-W Drill achieve full performance?
If the diamond core drilling machine doesn’t achieve full performance, check whether other power consumers are disrupting the power supply from the network or generator. Also, check the length of the extension cord used.
Why does the service indicator show nothing on my Hilti DD 30-W Drill?
If the service indicator on your Hilti Drill shows nothing, first check that the PRCD is functioning and switched on. If that's not the issue, there may be an interruption in the electric supply. Plug in another electric tool or appliance to check if it works, and inspect the plug connections, supply cord, power supply line, and main supply fuse. Another potential cause is water in the motor. If this is the case, allow the drill to dry out completely in a warm, dry place.
Why is water escaping from the chuck during operation of my Hilti DD 30-W?
If water escapes from the chuck of your Hilti Drill during operation, it could be due to a dirty core bit connection end or chuck. Try cleaning these parts. Alternatively, the chuck seal may be defective, in which case you should check the seal and replace it if necessary.
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.
