3. Start the drilling operation by pressing the
6.1.3 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.
