resharpen the diamond dry-cutting discs by
making several cuts in abrasive material, e.g.

cessive 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!

discs can cool.
