INTRODUCTION
This machine is for the intended purpose of diamond core drilling of concrete, masonry, stone and similar
materials. It must always be mounted on a drilling stand. This machine is for professional use only and only
trained personnel may operate this machine.
All other uses which are not for the intended purpose are prohibited.
It is equipped with a water feed system which is required for the diamond core drilling process. A PRCD
interrupter (portable residual current device) which must be used at all times.
It is equipped with a three or a four speed mechanical gearbox (depending on model) for different core drill
size ranges and features a mechanical safety clutch.
The motor has electronics for soft start, overload protection and thermal (overheating) protection. There is a
pulse function overload warning to alert the operator of load and overload conditions.
The machine is equipped with spirit levels which aid in aligning the
tool. By positioning the machine so that the bubble is in the center
of the window one can drill a straight hole. Use the Tubular Level for
horizontal aligning. Use the Bull's Eye Level for vertical aligning.

Under no circumstances should the tool be used when the power supply cable is damaged. A damaged
cable must be replaced immediately by an authorized Customer Service Center. Do not try to repair the
damaged cable yourself. The use of damaged power cables can lead to an electric shock.

WARNING: Always use the Portable Residual Current Device
(PRCD) also known as a Ground Fault Circuit Interrupter (GFCI).
Always use this device whenever using the machine to reduce
the risk of shock hazards. Always position the device PRCD
as close as possible to the power source. Test and reset the
PRCD device before each use. Press the “Test” button to test.
Press the “Reset” button to energize the circuit to the machine.
