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.
Preparation
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.
