Hand-guided wet-drilling with the water collection system

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.
Do not use the power socket on the wet vacuum extractor.
1. When using a vacuum extractor: Start the wet vacuum extractor and open the water supply.
2. Secure the side handle in the desired position.
3. Optional: Install and use the two-part hole-starting aid. → page 15
4. Plug the supply cord into the power outlet and press the "Reset" switch or the "I" button on the PRCD.
5. Center the diamond core drilling machine where the hole is to be drilled.
6. Slowly open the water flow regulator until the water flows at the desired rate. The indicator on the side
handle enables you to check the water flow.
7. Press the on/off switch on the diamond core drilling machine.

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.
For drilling upward, the use of a wet vacuum cleaner in conjunction with a water collection system is
a mandatory requirement!
1. Slowly open the water flow regulator until the water flows at the desired rate.
2. Switch the machine to continuous operation with the continuous running lock.
3. Release the carriage lock.
4. Turn the hand wheel until the diamond core bit is in contact with the work surface.

Using the Rota-Rail (column swivel)

The Rota-Rail allows quick and easy access to the hole or core being drilled, with no need to partly or
fully dismantle the system.
WARNING
Risk of injury caused by incorrect use! The drill stand can be damaged or it can break.
▶ Never use the Rota-Rail as a column extension.
1. Lock the carriage on the rail with the carriage lock. Check to ensure that it is securely fastened.
2. Remove the end stop screw from the end of the rail.
3. Attach the Rota-Rail so that the toothed racks are facing the same direction.
4. Tighten the screw on the Rota-Rail securely.
5. Release the carriage lock and run the carriage along the rail on to the Rota-Rail.
6. Slacken the securing screws of the Rota-Rail and turn the device to the left or right with the Rota-Rail.
This will give you access to the drillhole.
7. Remove the core or change the core bit.
8. Turn the tool with the Rota-Rail back to its original position and tighten the securing screws of the
Rota-Rail. Move the tool back to the column of the stand to resume work.
