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 1/8"-3/16" deep.
3. Release the on/off switch to stop the product. 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.

Dry-drilling with dust removal

Allowing dust to build up in quantity inside the core bit can cause imbalance.
When working, always route the suction hose to the rear and away from the diamond core drilling
machine, so that it cannot come into contact with the core bit.
▶ To prevent electrostatic effects, use an anti-static vacuum extractor.
7.4.1 Dry drilling with vacuum cleaner via built-in power outlet for electric devices
Use slotted core bits only when working without a dust removal system.
