6.1.4 Drilling in CUT-ASSIST mode
This section describes the procedure for a typical drilling operation in CUT-ASSIST mode.
The following preconditions must be fulfilled:
• The auto-feed unit is mounted correctly on the drill stand.
• The auto-feed unit and the diamond core drilling machine are paired and the Bluetooth connection
is established.
• The continuous-running lock on the diamond core drilling machine is activated.
•
The drilling operation has been started by pressing the button.
1. A "Surface search in progress" message appears on the display.
▶ The drilling system searches for the surface of the material to be drilled.
▶ The drilling system detects the surface.
2. The drilling system switches the cooling water supply on.
3. The drilling system starts drilling in hole-starting mode.
4. The drilling system switches to normal mode and carries out the drilling operation.
▶ The current drilling depth is shown on the display.
5. On detecting a break-through or a depth-gauge stop, the drilling system returns to its initial position.
▶ The diamond core drilling machine switches off.
▶ The cooling water supply is shut off.
The drilling depth displayed is the totaled drilling depth since the last break-through detection
without depth-gauge stop detection. Drilling progress between two consecutive detections equals
the total depth of a drillhole.
The information is displayed until a new drilling operation after a break-through detection or a
depth-gauge stop detection is started.
6.2 Viewing drilling statistics (during and after the drilling operation)
In CUT-ASSIST mode, the analysis data of the diamond core drilling machine are supplemented by analysis
data of the auto-feed unit. You can call up the analysis data in the following situations:
• During the drilling operation.
• After the drilling operation (EMERGENCY STOP switch pressed)
Call up the analysis data by pressing the button. To browse through the analysis data, repeatedly press
the button.
The read-out disappears automatically after 30 seconds.

Reset the 'Last Job' counter: You can manually reset all day counters (identifiable by the symbol)
of the available analysis data to 0:
•
Press the button and hold it down for at least 5 seconds.
You can call up the following analysis data on the auto-feed unit:
