Solution / measures

– Reduce the wire tension by adjust-

ing the saw head advance.

– Reduce speed

– Ensure that the speed potentiome-

ter on the remote control unit is set

to max.

– Install more water jets at the cut-

ting face.

– Increase the length of cut.

– Reduce the wire tension by adjust-

ing the saw head advance.

– Select a different diamond wire

specification.

– The diamond wire should be

installed so that it always runs in

the same direction, as specified.

– Always ensure that sufficient water

reaches the cutting face.

– Steel wedges must be used to pre-

vent movement of the concrete

sections.

– Any loose fragments or aggregates

must be removed from the kerf.

– Also refer to the D-LP 32 /

DS-TS 32 diamond wall saw

system operating instructions.

Problem

7. The diamond wire vibrates fiercely

and at a high frequency.

8. Diamond wire wear is excessively

high.

9. The diamond wire collapses.

(The diamond beads, connecting

pieces and separating springs are

bunched together on the wire.)

10. For information on finding and

eliminating faults in the

D-LP 32 (30) / DS-TS 32 (30)

wall saw system.

Possible cause

– Excessive wire tension

– Speed (r.p.m.) of the drive wheel is

too high.

– Drive wheel running too slowly.

The cutting speed of the diamond

wire is thus also too low.

– Inadequate cooling of the diamond

wire

– Length of cut too short

– Wire tension is too high in relation

to the length of cut.

– Very abrasive base material

– The direction of movement of the

wire is changed constantly.

– Inadequate cooling or no cooling of

the diamond wire

– The diamond wire becomes stuck

in the kerf and stalls during saw-

ing.
