5.1.9 Installing the water supply connection
CAUTION
Risk of personal injury and material damage The hose may become damaged if it is used incorrectly.
▶ 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.
Note
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 device and the water supply.
1. Connect the water flow regulator to the diamond core drilling machine.
2. Connect the water supply (hose connection).
5.1.10 installing the water collection system (accessory)
WARNING
Risk of personal injury and material damage If the diamond core drilling machine is damaged the
risk of electric shock is increased.
▶ Do not permit water to run over the motor and cover.
▶ Use of a wet-type industrial vacuum cleaner is mandatory requirement for drilling upward.
Note
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.
Note
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.
Note
When using the drill stand: Before installing the water collector holder, screw the spacer for the water
collector holder to the drill stand.
1. At the front of the drill stand, slacken the bottom screw at the rail.
