4. Preparations at the workplace
Planning the cutting sequence, marking the
cutting line and fastening points
1. 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.
2. If necessary, adjust the size and weight of the con-
crete blocks to the prevailing conditions by making
dividing cuts (i.e. depending on the work order, the
means of handling the blocks, the crane or the maxi -
mum floor loading capacity and size of doors).
3. Use steel wedges and supports, as necessary, to secure
the sections of concrete while sawing.
Clarifying the situation and securing the
workplace
Have you made sure there are no hazardous pipes or
cables (gas, water, electricity etc.) in the cutting area?
Have the effects of the cutting work on the stability of
the structure been clarified and are the supports in place
capable of taking up the resulting loads?
Can the possibility of hazards or damage as a result of
the cooling water used be ruled out?
Have safety measures been implemented to ensure that
no persons can be injured or property and equipment
damaged by falling objects or debris that may fly off dur-
ing the sawing operation?
Can the parts of the structure that are to be sawn out be
removed safely in a controlled operation and subse-
quently disposed of?
Does the electric supply and water supply available for
use meet the specified requirements?
Is the required equipment in the correct specification
available for use?
Has the work to be carried out been approved in full by
the site engineer or architect?

Electric power supply / fuse rating
-CAUTION-
Irrespective of whether using mains power or genera-
tor power, always check that an earth/ground conduc-
tor and ground fault circuit breaker are present in the
power supply and that these are connected. If in doubt
about a correct earth/ground connection in the power
supply, the E-box must be grounded with the ground
connection provided on the E-box. The fuse rating of
the electric power supply at the construction site must
be as follows:

Ground fault circuit breaker (FI)

X = phase 1, Y = phase 2, Z = phase 3, G = earth / ground (PE)
The power supply cable supplied with the tool has to be
used to connect the tool to the local power supply.
The remote control unit indicates the voltage and shows
an error in the event of any one of the phases (X, Y, Z)
providing no power.
Extension cables / conductor cross section
■
Use only extension cables which are approved for the
intended field of use and with conductors of adequate
cross section.
■
For extension cables use following cable specifica-
tion and minimum conductor cross sections: cable
extra hard type for wet and outdoor locations, 4 wires
AWG10, 3P+PE, 480 V / 30 A (conductor cross sec-
tion = cross-sectional area of individual conductors).
■
Inadequate conductor cross sections and long cables
result in a drop in voltage and may cause the cable to
overheat.
