Performing the core drilling operation

DANGER
Risk of injury due to failure to observe the danger zone! The auto-feed unit is always in Cut Assist mode after the diamond core drilling machine is switched on and it starts the automatic drilling process as soon as the confirmation button on the diamond core drilling machine is pressed. The core bit is automatically advanced until it contacts the surface of the object to be drilled.

• Make sure there is no-one in the danger zone!
• Keep the zone between the core bit and the surface of the object to be drilled clear!
  • Before you start drilling, check that the auto-feed unit is paired to the diamond core drilling machine. If the systems are not paired the EMERGENCY STOP switch has no effect!
  • Do not run more than one power tool at a time off a generator or transformer. Switching another power tool connected to the same generator/transformer on and off can cause under voltage dips and overvoltage spikes that can damage the product.

Positioning CUT-ASSIST

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 display shows “Position CUT-ASSIST”.

Parameters to be set on the auto-feed unit

Before you start the drilling operation, you can set certain parameters for the current drilling operation. The settings are saved for as long as the system remains connected to the electricity supply. When the power supply is disconnected, the parameters are reset to the factory default settings.
You can set the following parameters:

Power reduction
In overload situations on the jobsite, the system’s power draw can be reduced. This means that drilling can continue without interruption. Reducing current consumption is comparable with reducing contact pressure when using the diamond core drilling machine in manual mode.

There is a choice of 3 settings:

1. Minimum power
2. Medium power
3. Maximum power
   The factory default setting for power reduction is maximum power.

Overhead drilling
The system does not open the water valve until you switch the diamond core drilling machine on. When you have to carry out overhead work you can change this setting, for example to fill the core bit with water while the motor is stopped, or to drain the core bit and then set it in motion.

There is a choice of 2 settings:

1. Manual actuation
2. Automatic actuation
   The factory default setting for power reduction is automatic actuation.

Hole-starting mode for drilling at an angle and for small diameters (less than 25 mm)
Hole starting in general is done with sharply reduced contact pressure and low speed. When holes have to be drilled at an angle or the diameter of the core bit is less than 25 mm, it is advisable to start the hole at high speed

There is a choice of 2 settings:

1. Standard control: Low speed in 1st gear and 2nd gear, high speed in 3rd gear
2. Alternative control: High speed in all gears.
   The factory default setting for hole-starting mode is low speed in 1st gear and 2nd gear, high speed in 3rd gear.

Break-through detection

WARNING

Risk of injury! Injury can result if someone is in the danger zone when the core bit breaks through. With automatic break-through detection deactivated, after the hole has been drilled right through the material the core bit continues to rotate and does not stop automatically.

• Make sure there is no-one in the danger zone.
• Fit the depth gauge

You can deactivate automatic break-through detection, for example when you are going to drill very deep holes or drill into heterogeneous materials with possible voids.

There is a choice of 2 settings:

1. Break-through detection activated
2. Break-through detection deactivated
   The factory default setting for break-through detection is break-through detection activated.

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 drill hole.
The information is displayed until a new drilling operation after a break- through detection or a depth-gauge stop detection is started.

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:
