overcutting at corners is permitted. If not, the corre-
sponding corner holes must be planned and drilled first.
■
Check that the area is cordoned off, that supports are
in place and warnings to third parties are displayed.
Planning the cutting sequence, marking the
cutting line and fastening points
■
The parts to be cut out are usually marked by the client.
A rational cutting sequence can be followed when the
rail supports are cleverly positioned.
■
If necessary, adjust the size and weight of the concrete
blocks to the prevailing conditions by making dividing
cuts, e.g. in accordance with the work order, the means
of handling the blocks, the crane or the maximum floor
loading capacity.
Steel wedges can be used as necessary to secure the cut-
out concrete blocks.
Designation: steel wedge
Supporting / securing concrete blocks
Concrete blocks with a weight of several hundred kilo-
grams may be cut out during sawing. Secure the blocks
as necessary, before beginning sawing, as shown in the
following examples:

Preparations at the workplace and
preparing the equipment
Observe the safety precautions listed in section 5.
Power requirements and cooling water
■
Check the electric supply fuse rating (63 amps is best
and 32 amps is the minimum) and check functionality
of the earth connection (this is the responsibility of the
site manager).
■
Use an electric extension cable with standard Euro plug
as per EN CEE 63. Select the cable cross section accord-
ing to the load it is to carry (amps) and the cable length.

■
The CEE 63 plug, male type, complies with the IEC 309-
2 standard.
■
Ensure that the water supply has a max. pressure of
6 bar and a flow rate of at least 7 l/min. at a tempera-
ture of less than 20°C.
■
Make suitable arrangements for water removal, depend-
ing on the job and situation, e.g. water barriers, wet-
type vacuum cleaner, cover with plastic sheets, etc.
Clarify the situation and secure the workplace
■
Obtain approval from the site engineer or site man-
agement before beginning sawing. Find out whether
