COMMISSIONING
3.1. Connections and operating materials
Connection of electricity
A reliable power source with an operating voltage (230V) and corresponding fuses as
shown on the model plate must be available. The automatic phase inverter automatically
regulates the direction of rotation. Never operate the machine without the equipped
portable residual current device (PRCD).
Water connection - Cooling
The core drill motor has integrated water cooling. If the core drill motor is put into
operation for drilling, it must be cooled with fresh water. The cooling water is fed
directly into the tool through the integrated water cooling. Drilling without water is
prohibited!
3.2. PRCD Switch
This drill has a portable residual current device (PRCD) hard wired into the power cable. In an
event of a short circuit, power surge, electrocution or power outage (voltage drop), the PRCD will
sever the power to the drill. After the problem has been resolved, reset the PRCD by simply
pressing the GREEN reset button on the device. Halten Sie den FI-Schalter von fließendem oder
stehendem Wasser fern.

Keep the PRCD away from any running or standing water.

Before operating the drill test the PRCD to make sure it is functioning properly.
 Never use the drill if the PRCD is non-operational.
 To check the PRCD press the test button.

Never tamper with the power cable plug head.
3.3. Carbon Brushes
As soon as the carbon brushes are almost worn out the core drill machine significantly loses
power. Replace the carbon brushes as soon as you notice a significant loss of power.
 Do not wait until the carbon brushes are completely worn out, as this leads to damage to
the motor.
