8. Operation and the sawing procedure
Checks while sawing is in progress
CAUTION
Stay close to the control panel while sawing is in
progress so that you are ready to press the emer-
gency stop button at any time.
■
Do not enter the danger zone, for example, to adjust
the water nozzles, guide pulleys or advance pressure
cylinder or to drive wedges etc. before ensuring that
the saw drive has come to a standstill and the drive unit
has been switched off (power switched off).
■
Check that the sawing wire is adequately cooled and
adjust the direction of the jets to ensure that sufficient
water reaches the cutting face.
■
Check that the wire runs smoothly, without vibra-
tion. If the wire begins to vibrate, the guide pulleys must
be realigned or the advance pressure adjusted.
■
Take care to ensure that the hydraulic pressure
(DS WS10) remains within the 80 to 120 bar range or,
respectively, the electric current drawn (DS WS10-E)
remains just below the red area on the gauge. If the
pressure (DS WS10) or current (DS WS10-E) drops
below the optimum value, it can be raised by increas-
ing the pneumatic advance pressure or, respectively,
by reducing the radius of the cutting arc.

Readjusting saw advance at the end of the

advance movement locking lever
on the carriage.
