5.13 DD-ST 200: Securing the diamond core drilling machine to the drill stand
DANGER
Risk of injury Impact as a result of a fast-moving lever or hand wheel when the carriage is in motion.
▶ The lever and the hand wheel must not be fitted on the drill stand when the diamond core drilling machine
is being fitted.
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.
The drive unit and the carriage form a unit. The diamond core drilling machine can thus be removed
from the drill stand together with the carriage.
Adjust the play between the rail and carriage before using the tool for the first time.
1. Remove the end stop screw from the end of the rail.
2. Ensure that the carriage lock is open.
3. Mount the diamond core drilling machine on the drill stand by sliding the opening in the carriage over the
end of the rail.
4. Lock the carriage on the rail by turning the carriage lock through 90°.
5. Slightly turn the hand wheel to ensure that the diamond core drilling machine is securely fastened.
6. Refit the end stop screw to the end of the rail. The safety-relevant end-stop function becomes inoperative
if this component is not fitted.
5.14 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 (accessory) may be fitted between the tool and the water supply hose.
1. Connect the water flow regulator to the diamond core drilling machine.
2. Connect the water supply (hose connection).
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 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 cleaner.
