Setting up the wire cooling system
■ Ideally, hoses should be
led from the 2 water con-
nections with valves at the
front of the control unit to
the flexible water supply noz-
zle at the point where the wire
enters the front side of the
object being cut and to the
second (long) water supply
nozzle positioned at the diamond wire on the rear side
of the object. The water supply nozzles can be mounted
by pushing the wedge into the kerf or temporarily by
some other suitable means.
■ When dry cutting, the water outlet from the drive unit
is fed into the drainage system or a reservoir and not to
the saw kerf.
■ The cooling water supply is controlled by the ON and
OFF buttons on the control unit.
■ If less water than required for cooling the drive unit
is used for cooling the wire, a proportion of the water
can be fed directly into the drainage system by way of
the second valve located at the front of the drive unit.

Basic applications
Standard vertical cut
■ Illustration: Using a single-pair pulley stand
(DS-WS-SPP)
■ Optimum length of cut
■ Avoid a tight radius in the concrete
■ Good cutting performance (cutting speed)
■ Normal rate of wire wear

step
■ Illustration: Using a double-pair pulley stand
(made up from two DS-WS-SPP)
■ Relatively short length of cut
■ High cutting performance (cutting speed)
■ Slightly higher rate of wire wear
■ Note: Once the kerf reaches the height of the pulley
, rotate the pulley so that it points downwards.
