2.0 General instructions
2.1 Application
Core drilling machines may be used in accordance with the data shown on the model plate. The details in
the quotation and order confirmation also apply for the use of special machines.
The core drilling machines generally comply with safety class I, this alone ensures the complete protection
of the RCCB or PRCD.
When using suitable core bits it is possible to drill holes in the most diverse materials:
- Concrete (even with thick reinforcement steel)
- Sandstone and limestone
- All building materials for solid walls
- Asphalt floors
Warning
For manual drilling the machine may only be used for dry drilling as set out in the rele-
vant international regulations. Always use a 110 V isolation transformer and the suit-
able core drilling machine for wet drilling.
For stand-mounted drilling the machine may have the following
- a personnel safety switch (RCCB or PRCD) on the machine itself or
- a coded (1 h) plug, which is connected to the 115 V mains via a safety box (IP44) with an RCCB.
The core drilling machines comply with the regulations of the “Stone and Earth” professional associa-
tion dated July 1989. They are machines of category II, which means that they must be mounted on
stands and stable (pursuant to DIN 57100 and VDE 0100), and the stand must be fitted with the fol-
lowing
- reversing lock
- water extraction device.
2.2 Safety
Warning
Before using the machine for the first time, check that the conformity of the data
on the model plate with the mains voltage and frequency. Voltage deviations of ±
5 % and/or voltage deviations of ± 2 % are permissible. Repairs must only be
completed by quality persons who have suitable training and qualifications.
The following points are to be given special attention:
- the technical data and details of the permitted use of the machine (commissioning, ambient and
operating conditions) which are set out in the catalogue, the operating manual, the model plate
data and other product information,
- the relevant accident prevention regulations
- the correct use of tools
- the use of personal safety equipment
