6.8
Dry-drilling with dust removal
Allowing dust to build up in quantity inside the core bit can cause imbalance.
▶
To prevent electrostatic effects, use an anti-static vacuum extractor.
6.9
Use of the two-part hole-starting aid
CAUTION
Risk of injury caused by incorrect use!
Parts can come off the hole-starting aid if it is not pressed against
the work surface.
▶
When a two-part hole-starting aid is used, do not run the diamond core drilling machine without the
hole-starting aid pressed against the work surface.
A different hole-starting aid is required for each core bit diameter.
1. Fit the hole-starting aid into the open end of the diamond core bit.
2. When you start drilling apply only light pressure until the core bit has centered itself. Then apply more
pressure. Drill a guide cut 3-5 mm deep.
3. Release the on/off switch to stop the machine. Wait until the core bit comes to a complete stop.
4. Remove the hole-starting aid from the core bit.
5. Position the core bit in the guide cut, press the on/off switch and resume drilling.

Using a vacuum extractor with power outlet for power tools
Use slotted core bits only when working without a dust removal system.
1. Secure the side handle in the desired position.
2. Optional: Install and use the two-part hole-starting aid. → page 39
3. Plug the diamond core drilling machine's supply cord into the power outlet of the vacuum extractor.
4. Plug the vacuum extractor’s supply cord into the power outlet.
5. If connected: press the "Reset" switch or the "I" button of the PRCD.
6. Center the diamond core drilling machine where the hole is to be drilled.
7. Press the on/off switch on the diamond core drilling machine.
The vacuum extractor will start after the power tool has started. When you switch off the power
tool the vacuum extractor will run on for a short time before switching itself off.
