CAUTION
Risk of injury Hazard presented by inadvertent starting of the diamond core drilling machine.
▶ The diamond core drilling machine should not be connected to the power supply during set-up.
1. Lock the carriage on the rail with the carriage lock.
2. Pull out the eccentric pin for locking the diamond core drilling machine on the carriage.
3. Fit the diamond core drilling machine onto the carriage or the spacer.
4. Push the eccentric pin into the carriage or the spacer as far as it will go.
5. Tighten the eccentric pin.
6. Fasten the supply cord in the cord guide to the carriage cover.
7. Check to ensure that the diamond core drilling machine is securely fastened to the drill stand.

Fitting the water connection (accessory)
ATTENTION
Hazard due to incorrect use! Incorrect use can result in irreparable damage to the hose.
▶ Regularly check the hoses for damage and make sure that the maximum permissible water supply
pressure (see "Technical data") is not exceeded.
▶ Make sure that the hose does not come into contact with rotating parts.
▶ Make sure that the hose is not damaged as the carriage advances.
▶ Maximum water temperature: 40 °C.
▶ Check the water supply system to ensure there are no leaks.
To avoid damage to the components, use only fresh water containing no dirt particles.
A flow meter can be inserted as an accessory between the machine and the water supply.
1. Connect the water flow regulator to the diamond core drilling machine.
2. Connect the water supply (hose connection).
5.11
installing 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 slab. The water collection system
sealing disc must match 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. At the front of the drill stand, slacken the bottom screw at the rail.
2. Slip the water collector holder behind the screw from below.
3. Securely tighten the screw.
4. Position the water collector, with seal and water collector sealing disc installed, between the two movable
arms of the holder.
5. Secure the water collector to the holder with the two screws.
