Make sure that the segments are well cooled. If the drilling water is

clear, the segments are well cooled.
Overhead-drilling only with water collection ring.

In case of frost warning, drain the water system.

Drill bits with an external thread R ½" can be screwed directly in the work
spindle. Always use drill bits matching the material which has to be drilled
You can treat the machine carefully by using only drill bits that are balanced
and undeformed. Pay attention that the segments of the tool have enough
relief cut toward the drill bit body.
Drill Bit Changing
Attention!
When you use or sharpen the machine, it might heat up enormously.
You could burn your hands or get cut or ripped by the segments.
Therefore, always use protective gloves when changing the drill bit.
The drill spindle has a right-hand thread. To hold on spindle use an jaw
wrench SW 32. Never remove the drill bit with impacts because this way the
machine will be damaged. With some waterproof grease which is put on the
drill bit thread you can remove the drill bit easier. It is also a good help for
easy removing to put a copper ring between the spindle and the drill bit.
Quick-change adapter
With the quick-change adapter included in delivery drill bits with R ½" male-
connection can be changed without any tool or the EIBENSTOCK-diamond
wet drill bits bayonet can be fixed directly on the adapter.
The coupling piece of the quick-change adapter which is screwed on the
R ½" male-drill bit or the connection of the diamond wet drill bits bayonet are
put that way on the quick-change adapter that its flutes can be pushed on the
grooved pins of the adapter. By using an adequate pressure push the
coupling piece or the drill bit on the adapter until it stops (Fig.1) and turn it
about 90° against the rotating direction of the machine (Fig. 2). In order to
change the drill bit and to remove the drilling core proceed in reverse order.
