8.3.2 Undercut
Do not cut into the base course (frequently chip‐
ped stones and gravel) when cutting roadway
pavement – cutting in chipped stones and gravel
is revealed by light-colored dust – excessive
undercut may occur as a result – Danger of shat‐
tering!
8.3.3 Built-up edges, sharpen
Built-up edges take the form of a light gray
deposit on the tops of the diamond segments.
This deposit on the segments clogs the dia‐
monds and blunts the segments.
Built-up edges can form:
– when cutting extremely hard materials, e. g.,
granite
– with incorrect handling, e. g., excessive feed
effort
Built-up edges increase vibration, reduce cutting
performance, and cause formation of sparks.
At the first signs of built-up edges, immediately
"sharpen" the diamond abrasive wheel – to do
this, briefly cut through abrasive material such as
e. g. sandstone, aerated concrete or asphalt.
Addition of water prevents the formation of built-
up edges.

9 Mounting an Abrasive Wheel
If work continues with dull segments, these may
soften due to the high heat generated – the
parent wheel is annealed and its strength is com‐
promised – this can lead to stresses that are
clearly recognizable by gyrations of the abrasive
wheel. Do not continue to use the abrasive wheel
– Risk of accident!
9 Mounting an Abrasive
Wheel
Only fit or replace when the machine is switched
off – retaining latch moved to ƒ, battery
removed.
