Stihl TS 480i Instruction Manual page 7

WARNING
When wet cutting at the
recommended flow rate
is not utilized, the opera-
tor should always wear a
respirator approved by
NIOSH/MSHA for the
material being cut to
reduce the risk of serious
or fatal respiratory illness.
For additional details and
warnings on this subject,
see information under
"Working Conditions" in
this instruction manual.
THE POWER TOOL
For illustrations and definitions of the
parts of the cut-off machine, see the
chapter "Main Parts."
WARNING
Never modify a cut-off machine in any
way. Only STIHL branded parts and
cutting attachments expressly approved
by STIHL for use with the specific STIHL
cut-off machine models are
recommended. Although certain other
parts or attachments may be useable
with the STIHL powerhead, their use
may, in fact, be extremely dangerous.
Abrasive Wheels
WARNING
Before mounting the cutting wheel,
make sure that the maximum operating
wheel speed is above or equal to the
spindle speed of your cut-off machine as
TS 480i, TS 500i
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.
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. Always store your cut-off
machine in a place where a 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.
