WARNING
Risk of personal injury and material damage The diamond core bit fills with water during overhead drilling.

▶ As a first step, carefully allow the water to drain away after completing overhead drilling. This is done
by disconnecting the water supply from the water flow regulator and draining the water by opening the
water flow regulator. Do not allow the water to run over the motor and cover.
1. Connect the water flow regulator to the diamond core drilling machine.
2. Remove the diamond core bit from the hole.
3. Switch off the diamond core drilling machine.
4. Lock the carriage on the rail with the carriage lock.
