Required space for operation and maintenance
If possible, make sure that you have enough free space for operation and
maintenance around the machine (about 2 metres). This way, you can
work safely and in case of operating trouble you can intervene
immediately.
When you drill into blocs, make sure that the blocs are well anchored

and fixed.
Before drilling in supporting parts, make sure that you do not

disregard the statics. Observe the instructions of the experts who are
responsible for the design.
Make sure that you do not damage any gas mains, water mains or

electric cables while drilling.
Pay attention that you do not touch any metallic parts of the machine

when you drill walls and grounds where electric cables could lie
under water.
Pay attention that the drilling core does not hurt anybody or damaging

anything when it drops out.
If the drilling core might cause any damage when it drops out, use an

device that can hold back the drilling core.
Make sure that the drill bit is well fixed.

Only use tools which are suitable for the particular material.

Fastening of the Drill Rig
The diamond core drill EBM 250/2 RP may only be used mounted on a
drill rig. Since the drill rig is not included in the delivery, we point out some
important kinds of assembly.
For this purpose, please refer to the drill rig's operating instructions.
Vacuum fastening:
Re. vacuum fastening, make sure that you have a sufficient vacuum
(minimum -0.8 bar). Make sure that the gaskets are not worn.
Attention! Do not use the vacuum fastening on the wall or overhead!
Do not forget that the levelling screw may be turned out only up to a
certain extend in order not to destroy the vacuum.
Dowel fastening:
The most common way of fastening is dowel fixing.
If possible, use metal dowels only. The dowel diameter must not be
smaller than 12 mm.
In order to fasten the drilling unit correctly, you need the fastening set

(order number 35720000).
Drill a hole with a diameter of 16 mm, 50 mm deep. Make sure that

the hole is free of dust.
