Trouble or fault Possible cause Action to be taken
The wire saw doesn’t
start.
A new sawing wire jams in a
kerf made by a worn sawing
wire.
▶
Complete the cut with the
worn sawing wire or use a
thinner sawing wire.
▶
Drill another hole that can
be used to draw the new
sawing wire into position.
Sawing-wire-to-concrete
contact length is excessive.
▶
Install more guide pulleys
or release pulleys.
Tension on the wire is too
high.
▶
Reduce tension on the
wire by adjusting the
pneumatic control valve.
Sawing wire installed wrong
way round.
▶
Check the sawing wire is
installed for the correct
direction of travel.
The wire is defective.
▶
Replace the sawing wire.
The drive pulley slips /
the wire is not driven by
the pulley.
Insufficient wire tension.
▶
Increase the wire tension.
The drive pulley is too badly
worn.
▶
Replace the drive pulley.
The wire jumps off the
drive wheel or guide
pulley when starting the
saw.
The starting lock was not
used.
▶
Use the starting lock (lock
the sleeve directly at the
air cylinder).
Sawing wire installed wrong
way round.
▶
Check the sawing wire is
installed for the correct
direction of travel.
Uneven / one-sided
wear of the sawing wire.
The diamond wire was not
twisted before connecting
the ends together.
▶
For each meter of length,
twist the sawing wire
approximately 1 to 1.5
turns counter-clockwise,
as viewed toward the
join. After each major cut,
retwist the sawing wire
with a different number of
turns.
Wire breakage right
beside the connector.
The wire passes round a
sharply angled corner on
the object being cut.
▶
Install additional guide
pulleys to reduce the
angle of deflection.
Material fatigue of the saw-
ing wire due to excessively
long usage and aging.
▶
Use a new sawing wire.
Material fatigue of the saw-
ing wire due to excessive
bending at the connector.
▶
Reduce bending of the
wire with articulated
connectors.
The sawing wire is
pulled out of the
connector.
Insufficient pressure applied
to the crimping pliers.
▶
Use a press crimping tool
rated for at least 8 t.
Incorrect or worn crimping
