Stihl TSA 230 Instruction Manual page 27

Do not cut any unauthorized materials.
Cut-off machines are not suitable for
cutting certain metals and other
substances.
Never use diamond abrasive wheels
with abrasive material on their sides,
since in a pinch situation, they can result
in extreme kickback – Risk of severe or
fatal injury.
Short names
The short name is a combination of
letters and numerals with up to four
digits:
The letters indicate the main area of
–
use for the cutting wheel.
The numerals indicate the
–
performance class of the STIHL
diamond cutting wheel.
Radial and axial run-out
A correctly mounted spindle bearing on
the cut-off machine is essential for a
long service life and efficient operation
of the diamond cutting wheel.
Using a cutting wheel on a cut-off
machine with a malfunctioning spindle
bearing can lead to axial and radial run-
out.
TSA 230
Excessive radial run-out (A) causes
individual diamond segments to be
overloaded and to overheat. This can in
turn lead to stress cracking in the wheel
core or to softening of individual
segments.
Axial run-out or spindle wobble (B)
results in higher thermal stress and
wider cuts.
