Possible cause
Fatigue breakage of the
loadbearing wire.
Wire tension is too low or
too high.
The guide pulleys are not
aligned exactly.
The guide pulleys are too far
apart (length of unsupported
wire is too long).
The guide pulley is worn, out
of round or a stone is stuck
in the guide groove.
Not connected to the elec-
tric supply.
The compressor is not
switched on.
The tank of the compressor
connected to the control unit
is empty.
The electric supply is dead –
no voltage.
The main switch is in the
"Off" position.
Action to be taken
▶ Reduce stress through
use of flexible connectors.
▶ Use only one connector
per endless wire loop if
possible.
▶ Use a new wire if break-
ages occur in quick suc-
cession.
▶ Optimize the tension by
adjusting the pressure.
▶ Adjust the pulleys to
bring them exactly into
alignment.
▶ Reduce the length of
unsupported wire by
fitting additional pulley
stands.
▶ Position the wire saw
closer to where the cut is
being made.
▶ Check that the pulleys run
exactly true and replace
them if necessary.
▶ Check that the guide
grooves are free of foreign
matter and clean them if
necessary.
▶ Connect to the electric
supply.
▶ Switch the compressor
on.
▶ Disconnect the air hose
from the compressor and
allow the compressor to
run until it is switched
off by the pressure valve.
Then reconnect the air
hose.
▶ Check the main supply
fuse at the site distribution
box.
▶ Switch on at the main
switch.
