■
The diamond wire wears too quickly
Possible cause
Solution / measures
Drive speed is too low and wire cutting speed is thus also
– Increase drive speed or, respectively, cutting speed.
too low.
Inadequate cooling of the diamond wire
– Set up more water nozzles at the cutting face.
Wire cutting length too short
– Increase the cutting length (length of contact).
(length of contact between the wire and the concrete)
Wire tension too high relative to length of cut.
– Reduce the tension on the wire by adjusting the air
pressure regulation valve.
Very abrasive material being cut.
– Select a different diamond wire specification.
The direction in which the wire runs is changed continually. – Always fit the diamond wire so that it runs in the same,
specified direction.

The diamond wire collapses
(The diamond beads, connecting pieces and separating springs are bunched together on the wire.)
Possible cause
Solution / measures
Diamond wire not cooled adequately or not cooled at all
– Always ensure that sufficient water reaches the cutting
face.
The diamond wire becomes stuck in the kerf and stalls
– Steel wedges must be used to prevent movement of

the concrete sections.
– Loose fragments or aggregates must be removed from
