machine as provided in the
specifications of this manual. A wheel
that is not so rated may shatter or break
and poses a threat of serious or fatal
injury to the operator and other nearby
persons.
Abrasive wheels for free-hand cutting
are subjected to particularly high
bending and compression stresses.
WARNING
Never use a reducer bushing inserted
into the wheel to reduce the diameter of
the arbor hole. It may slip out of place,
causing out-of-roundness, vibration and
wheel breakage.
WARNING
Wheels that are not STIHL branded may
be more likely to shatter or break or
create other hazards, such as increased
reactive forces. Use only wheels with
approved RPM ratings. Read and follow
any addional safety precautions that
accompany the wheel.
WARNING
Inspect the abrasive
wheel frequently and
replace immediately if the
abrasive wheel is
cracked or warped.
Cracked or warped
wheels may shatter or
break and cause serious
or fatal personal injury.
Out-of-round or unbal-
anced abrasive wheels
increase vibration and
reduce the service life of
the cut-off machine.
TSA 230
Some diamond abrasive wheels that are
not STIHL branded utilize poor quality
steel cores, are not properly tensioned,
or have other design or manufacturing
defects. As a result, they may begin to
wobble during use, which can cause
wheel breakage. Such wobbling can
also lead to a severe binding of the
wheel in the kerf, that, under certain
circumstances, can then result in
serious or fatal injury from reactive
forces. See the section entitled
"Reactive Forces including Kickback."
Never use a wheel that wobbles or that
has ever wobbled. Even though such a
wheel may temporarily cease to wobble,
e.g., if run without load, it will always be
prone to wobble again under certain
conditions. Replace it immediately
before further use.
Composite abrasive wheels are heat
sensitive. During a break, always place
your cut-off machine in a location where
the composite wheel is not exposed to
direct sunlight or other sources of heat.
Store spare composite wheels flat on a
level surface in a dry place where there
is no risk of frost damage. Failure to
follow these directions may cause the
wheel to shatter or crack in use causing
serious or fatal injury.
WARNING
Never use circular saw
blades, carbide tipped
blades, rescue blades,
wood-cutting blades or
toothed blades of any
nature. They can cause
severe personal injury
from blade contact,
thrown objects and/or
reactive forces, including
kickback. See section on
"Reactive Forces includ-
ing Kickback." Your
STIHL dealer stocks a
range of special abrasive
wheels for the many
applications of the cut-off
machine.
WARNING
Use of the wrong abrasive wheel or the
cutting of material for which the wheel
was not designed may cause the wheel
to wobble, shatter or increase reactive
forces, causing serious or fatal injury.
See below and section "Reactive Forces
including Kickback."
Only use the abrasive wheel approved
for the type of material to be cut. There
are different types of abrasive wheels,
each specially marked.
For cutting composite materials please
ask your STIHL dealer.
Diamond Abrasive Wheels
Diamond abrasive wheels have a much
better cutting performance than
composite abrasive wheels. The
