Mounting An Abrasive Wheel - Stihl TSA 230 Manual De Instrucciones

English
Undercut
Do not cut into the base course
(frequently chipped 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 shattering!
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 diamonds 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
58
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.
If work continues with dull segments,
these may soften due to the high heat
generated – the parent wheel is
annealed and its strength is
compromised – 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!
