Preparing To Drill Using The Drill Stand; Connecting The Vacuum Removal System - Hilti DD 30-W Manual

Note
Diamond core bits must be replaced when the cutting performance and/or rate of drilling progress
drops significantly. This generally is the case when the segments reach a height of less than 2 mm.
Note
Spraying the chuck with Hilti lubricant spray at regular intervals makes it easier to fit the core bit.
1. Unplug the supply cord from the power outlet.
2. Open the chuck by pulling the chuck locking lever upwards as far as it will go.
Note
Check that the core bit connection end and the chuck are clean and undamaged.
3. Tip the water collector about its mounting axis as far as it will go.
4. Guide the cutting edge of the core bit into the sealing ring in the water collector from above.
5. Align the connection end of the core bit with the corresponding openings and insert it into the chuck.
6. Turn the core bit as far as it will go while applying light pressure.
7. Secure the core bit by closing the chuck locking lever.

5.2.7 Connecting the vacuum removal system

1. Make sure that the suction hose from the all-purpose vacuum cleaner is securely connected to the core
drilling machine's water collection hose. Use a hose adapter for this purpose.
2. Connect the all-purpose vacuum cleaner suction hose to the vacuum cleaner.
3. When drilling overhead, use the retaining clip on the side handle to secure the water collection hose.

5.3 Preparing to drill using the drill stand

WARNING
Risk of injury. The drill stand may tip over or rotate if inadequately fastened.
▶ Before using the diamond coring machine, fasten the drill stand securely to the working surface
with an anchor or with a vacuum base plate.
▶ Use only anchors of a type suitable for the applicable material and observe the installation
instructions issued by the anchor manufacturer.
▶ Use a vacuum base plate only when the working surface is suitable for fastening the drill stand by
way of the vacuum fastening method.
The drill stand and the machine can be fastened either using the vacuum base plate or the DD M12 S
accessory set, i.e. using an HKD-D M12x50 anchor, the DD-LR-CLS clamping spindle and the DD-LR-CLN
nut.
