6. Preparing the saw system for use
Planning the wire guidance system
■ Before installing the wire saw, you must carefully
study the situation and plan the wire guides, the drilling
of through-holes, the sequence of the work and the pro-
cedure involved. You must also plan the cooling water
supply and, if necessary, waste water disposal.
■ Consideration must be given to safety aspects and
cordoning off to prevent access by third parties etc.
■ Secure the area, plan the removal and transportation
of the sawn-out sections of the structure and all other
necessary measures.

Drilling through-holes for the wire
■ According to the situation, the material to be cut and
the amount of reinforcement in the concrete, a hammer
drill and long masonry drill bits or a diamond coring
machine mounted on a stand can be used to drill through-
holes. Depending on the thickness of the section to be
cut and the material involved, we recommend drill bits
of 16 mm, 37 mm, 67 mm or 102 mm diameter.
■ Depending on the application, you will also require
accessories and special solutions for drilling to greater
depths.
Setting up the electric supply
NOTE
■ The DS WS15 wire saw will run even when the elec-
tric supply has only 4 conductors (1 earth/ground and
3 phases). However, the two 230 V supply sockets on
the control unit will provide no power if the neutral con-
ductor is missing. In this case it will be necessary to use
a separate 230 V supply cord for the compressor, lights
or a rotary hammer drill etc.
■ Ensure that the electric power supply has a fuse rat-
ing of at least 16 amps. A fuse rating of 32 amps is ide-
al. The jobsite power connection must be earthed/ground-
ed and equipped with a 30 mA ground fault circuit break-
er (PRCD). The earth connection and ground fault cir-
cuit breaker must be tested before the saw is operated.
