To avoid damage to the components, use only fresh water containing no dirt particles.
1. Close the cover on the water swivel / suction head.
2. Connect the water flow regulator to the diamond core drilling machine.
3. Connect the water supply (hose coupling).
5.15
Fitting the water collection system (accessory)
WARNING
Danger of electric shock!
There is a possibility of water flowing over the motor and cover if the vacuum
removal system is faulty.
▶
Cease operations immediately if the vacuum removal system is not working.
The diamond core drilling machine must be at a 90° angle to the ceiling. The seal for the water
collection system must be of the correct size for the diamond core bit diameter.
Use of the water collection system allows water to be led away under control, thus preventing the
surrounding area from being heavily soiled. The best results are achieved with a wet-type industrial
vacuum extractor.
1. Remove the screw in the drill stand at the front of the rail.
2. Push the water collector holder into position.
3. Fit the screw and tighten it.
4. Fit the water collector between the two movable arms of the water collector holder.
5. Press the water collector against the work surface by turning the two screws on the water collector
holder.
6. Connect a wet-type industrial vacuum extractor to the water collector or establish a hose connection
through which the water can drain away.

Operation
6.1
Fitting a diamond core bit in a BI+ chuck
CAUTION
Risk of injury when changing the tool!
The tool becomes hot as a result of use. It may have sharp edges.
▶
Always wear protective gloves when changing the tool.
Diamond core bits must be replaced when the cutting performance and/or rate of drilling progress
drops significantly. Generally, this is the case when the segments have worn down to a certain height.
1. Lock the carriage on the rail with the carriage lock. Check to ensure that it is securely fastened.
2. Open the chuck by turning it in the direction of the "Open brackets" symbol.
3. From below, push the diamond core bit into the chuck on the diamond core drilling machine, turning it
until the teeth engage.
4. Close the chuck by turning it in the direction of the "Closed brackets" symbol.
5. Check that the diamond core bit is seated securely in the chuck.
6.2
Fitting the diamond core bit with an alternative type of chuck
1. Lock the drive spindle with a suitable open-end wrench.
2. Tighten the core bit with a suitable open-end wrench.
