Solution / measures

– Install additional guide pulleys.

– Reduce the wire tension by adjust-

ing the saw head advance. Don’t

exceed the specified pressure of

120–160 bar in the main hydraulic

circuit.

– Fit shorter wire couplings.

– Use the cardan-type, flexible cou-

plings recommended by Hilti.

– Check the setting of the crimping

pliers.

– Use Hilti crimping pliers with a

minimum pressure of 7 t.

– Check the crimping jaws and

replace if necessary.

– With all couplings available

from Hilti, the wire must always

be pushed in as far as it will

go.

– Reduce the wire tension by adjust-

ing the saw head advance.

– Increase wire tension by adjusting

the saw head advance.

– Install additional guide pulley

stands.

– Fit a shorter diamond wire.

– The front rail support (at the wire

distributor) should be fitted as

close as possible to the end of the

rail.

Problem

4. The wire breaks immediately

beside the coupling

5. The diamond wire is pulled out of

the crimped coupling.

6. The diamond wire thrashes about

and vibrates badly.

Possible cause

– The cutting radius of the diamond

wire in the concrete is too small.

– The wire has been used too long

under excessive tension.

– The wire coupling is too long.

– Crimping pliers incorrectly adjusted

– Insufficient pressure applied to the

crimping pliers

– Incorrect or worn crimping jaws

– The wire was not pushed far

enough into the coupling.

– Constantly excessive wire tension

during operation.

– Insufficient wire tension

– The pulley stands are too far apart

(excessively long unsupported wire

length).

– Rail support incorrectly positioned
