1.) General Safety Instructions
To ensure your and the safety of other persons watch the following points when handling the
equipment:
Any person intended for operation, maintenance and repair of the equipment, must be
familiar to the function and safety of the same.
Check the orderly condition and the safety of machines, tools, operation mediums and other
devices before you take up operation!
Always bear in mind that disturbances may result in an accidence.
Never open an equipment without switching off the power supply before.
Never repair any electric equipment yourself.
Such defects exclusively have to be repaired by an expert.
In no way safety devices may be removed.
During repair and maintenance works there is the danger that third persons start the machine
by mistake.
Therefore block up the switches with reliable means before you start working.
During the drilling and cutting work dangerous zones must be barricaded and marked in a
suitable way or safeguarded by a warning sentry against trespassers.
Persons occupied with demolishing works must wear protective helmets and also ear plugs.
Self-supporting constructions, like balconies and similar must be supported in a solid way or
safeguarded against crashing in another way, before parts, which secure the fixing or
anchoring of their pedestals, are demolished.
Any single structural parts which are detached from the construction, must be safeguarded in
a way, making their crash on an operator's position or lower ceilings impossible.
Besides this the special instructions for the assembly of the equipment and for the safety
must be watched and their strict observance secured.

2.) Possible risks when working with core drilling equipment
2.1 Statics of building construction
Before starting operation let a specialist check whether the borehole(s) intended to be made are a
risk for the statics of the building. Only realise the jobs if they have no influence on the statics of
the construction.
2.2 Fastening
If the drilling stand is fastened insufficiently, the possibility that somebody becomes insured
through the falling down of the drilling stand or rotation around the drilling axle is high.
So it is very important to watch the instructions for installation exactly.
2.3 Electric wires
Ensure yourself that no life wires are around the place where
the borehole shall be made. If you cannot exclude this let an electrician put your equipment to
earth as protection.
Ensure that your equipment is protected by an earth leakage circuit breaker.
Always wear shoes with rubber bottom!
2.4 Power failure
If you use a vacuum pump for the fastening of the core drilling equipment place it where you can
continuously watch the vacuum gauge during operation.
Immediately switch off the drilling drive when the vacuum pressure falls below 0,7 bar because
of a power failure or some other defect and make sure that the core drilling equipment cannot fall
down.
In case of a power failure switch off any electric equipment to prevent accidents in case the
machine starts again suddenly.
2.5 Loose bolted connections
Before starting operation make sure that all bolted connections are tightened. Loose parts can
result in accidents!

2.6 Noise
Use suitable ear plugs during drilling operation to avoid an impairment of your hearing.
2.7 Drill cores and other pieces of concrete
Make sure that the drill core or other loose pieces of concrete cannot become dangerous for any
persons or things by falling down after perforation (especially when perforating ceilings).
Safeguard these parts with supports or other suitable measures.
2.8 Unintentional start of the drilling motor
During installation, maintenance work or changing of tools you must in any case plug-off the
machine.
That means you must plug-off the electric drilling motor or if it is a hydraulic drive the plug of
the hydraulic unit and ensure that nobody can connect it with the power supply again without
your knowledge.
If you have a hydraulic drive it is sufficient if you disconnect the hydraulic hoses from the
hydraulic motor (snap closure plug-couplings).
