TRANSPORT
Note During transport the core drill motor must be disconnected from the power mains.
 Disconnect the power supply cable of the core drill motor from the power mains.

Remove the tool from the core drill motor.

Remove the core drill motor from the core drill stand.
OPERATION
Caution! The core drill motor must be cooled with water for drilling. Without this cooling the motor
overheats and will become faulty.
Danger! Avoid any contact with the running tool.
With this core drill motor water is used for cooling and for rinsing the core drill during drilling. To
supply the core drill motor with water, connect the included GEKA fitting onto the GEKA fitting
equipped on the core drill motor. Always use clean water for the core drill motor and ensure that
dirty water is properly removed from the drilling location. This contributes to longer service life of
the core drill and the water seals on the core drill motor. The water pressure must be maximum
three bar.
 Notice whether excessive vibrations occur on the core drill. If vibrations are too high the
drill can possibly jam or be damaged.
 Do not use any spiral core drill since in time this leads to damage of the drilling machine.

Make sure that no water escapes on the spindle. Replace the water seals in the drilling
machine immediately if leaks are detected.
 During drilling always pay attention to the intermittent overload protection and avoid an
overload of the drilling machine motor.
 Never operate the drilling machine if an electrical component or the cable is damaged.
Have a specialist repair the drilling machine.
 Never carry or pull the drilling machine by the power cable.

Only position the core drill on the workpiece when the drill has reached its maximum
speed.
 Change the gear setting only after the spindle has stopped completely.

If you want to replace a core drill, tightly hold the spindle with a key. Loosen the core drill
with another key. Never hit the bit to loosen it. This will damage the bit.
