Handling diamond dry-

cutting discs
•
Diamond dry-cutting discs must be stored,
handled and fitted carefully in accordance with
the manufacturer's instructions.
•
Too soft diamond segments:
f Diamond dry-cutting discs wear too quickly
at very high removal rate.
remedy: The material to be machined
requires diamond dry-cutting discs with a
harder bond.
•
Too hard diamond segments:
f The diamond grains become blunt and do
not break out of the bond. The diamond dry-
cutting discs no longer have any cutting
power.
remedy: The material to be machined
requires diamond dry-cutting discs with a
softer bond.
•
In the event of loss in cutting power
(recognisable by intensity of flying sparks)
resharpen the diamond dry-cutting discs by
making several cuts in abrasive material, e.g.
sandstone.
•
Work without applying pressure – the weight of
the machine is sufficient. Increased pressure
causes increased wear.
•
Excessive cutting pressure can cause material
fatigue in the base metal and therefore the
formation of cracks. Before use, ensure that
there are no cracks in the diamond dry-cutting
disc.
•
Diamond dry-cutting discs are designed for
straight cuts. If used to cut curves the blade
becomes deformed, causing internal cracks and
segments to break off (see "Chap. 3.5 Intended
use") – risk of injury!
•
The diamond cutter should plunge into the wall
only after the working speed has been reached
– green LED (3) lights up.
•
After approx. 2 minutes of cutting time the
machine should be run with no load for
10 seconds, so that the diamond dry-cutting
discs can cool.
