6. Preparing the saw system for use

nd
step
■ Disengage the wire from the release pulley when the
cut is approx. 50% complete, i.e. the wire then also begins
to cut from below.
■ Provided the operator remains outside the danger
zone, this can be done while sawing continues by means
of a long string: simply pull out the bolt from the release
pulley!

Release pulley
■ The wire is caught by pulleys
and
when it
escapes from the kerf at the end of the cut.
Example: Using a double-pair pulley stand for a
vertical cut through a concrete component
Distance “D” between the drive and object
being cut
■ The distance “D” between the drive unit and the object
being cut is determined by the application. The ideal dis-
tance, i.e. the “free wire length”, is approximately 2–3
m, but it can also easily reach 5–10 m. However, for even
greater distances, the wire must run over an additional
pulley stand. The distance “D” (or "free wire length”)
should always be kept as short as possible for safety
reasons.

Optimum length of cut “L”
■ The optimum length of cut “L”, i.e. the wire length
effectively involved in the cutting process, ranges from
approximately 2 to 8 m for the DS WS15 wire saw. This
enables the operator to achieve the greatest efficiency,
and also ensures good service life of the wire.
Standard horizontal cut
■ Position the drive unit at a short distance from the
object to be cut, with the tension side facing the object.
