Wire sawing work must frequently be carried
out under difficult conditions. The resulting
loose concrete parts are very heavy. Wire
sawing work must therefore be carried out in
close cooperation with specialists in the
structural strength of buildings.

The wire must not be led around extremely
sharp edges. Such edges must be rounded off
before sawing to at least a radius of 10 cm.

The last cut must be arranged so that the
sawn-out part does not jam the wire.
With respect to jamming of the tool (wire), wire
sawing is much less trouble than sawing with a
diamond saw blade, since the diamond wire
constantly cuts itself free.
In spite of this however we recommend the
following cutting sequence: First the lower,
horizontal cut should be made because in this
way the wire is least likely to become jammed,
if at the end the block falls into the cut.
The following cuts are less troublesome and
therefore can be made in any sequence.
