■ 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
during sawing. the concrete sections.
– Loose fragments or aggregates must be removed from
the kerf.
