5.12 Fitting the water supply connection 12
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 of 6 bar 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.
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).
5.13 Install water collection system for drill stand (accessory) 13
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.
1. Remove the screw from the drill stand.
2. Install the water collector holder on the drill stand with the screw.
3. Position the water collector, with the water collector sealing disk installed, between the two movable
arms of the holder.
4. Press the water collector against the work surface by turning the two screws on the water collector
holder.
5. Connect a wet-type industrial vacuum extractor to the water collector or establish a hose connection
through which the water can drain away.
