Catalytic converter
!Warning!
Some STIHL power tool
models are equipped with
a catalytic converter,
which is designed to
reduce the exhaust
emissions of the engine
by a chemical process in the muffler.
Due to this process, the muffler does not
cool down as rapidly as conventional
mufflers when the engine returns to idle
or is shut off. To reduce the risk of fire
and burn injuries, the following specific
safety precautions must be observed.
!Warning!
Since a muffler with a catalytic converter
cools down less rapidly than conven-
tional mufflers, never set your power tool
down where the muffler is near dry
brush, grass, wood chips or other
combustible materials while it is still hot.
Let the engine cool down sitting in the
upright position on concrete, metal, bare
ground or solid wood away from any
combustible substances.
!Warning!
An improperly mounted or damaged
cylinder housing or a damaged/
deformed muffler shell may interfere
with the cooling effect of the catalytic
converter. To reduce the risk of fire or
burn injury, do not continue working with
a damaged or improperly mounted
cylinder housing or a damaged/
deformed muffler shell. Your catalytic
converter is furnished with screens
designed to reduce the risk of fire from
the emission of hot particles. Due to the
heat from the catalytic reaction, these
screens will normally stay clean and
need no service or maintenance. If you
experience loss of performance and you
suspect a clogged screen, have your
muffler maintained by a STIHL Servicing
Dealer.
Working Conditions
Operate and start your power tool only
outdoors in a ventilated area.
Operate the power tool under good
visibility and daylight conditions only.
Work carefully.
!Warning!
Your power tool produces
toxic exhaust fumes as
soon as the engine is
running. These gases
(e.g. carbon monoxide)
may be colorless and
odorless. To reduce the risk of serious or
fatal injury from inhaling toxic fumes,
never run the power tool indoors or in
poorly ventilated locations.
!Warning!
Use of this product can generate dust
and fumes containing chemicals known
to cause respiratory disease, cancer,
birth defects, or other reproductive
harm. If you are unfamiliar with the risks
associated with the particular dust or
fume at issue, consult your employer,
governmental agencies such as OSHA
and NIOSH and other sources on
hazardous materials. The State of
California and some other authorities,
for instance, have published lists of
substances known to cause cancer,
reproductive toxicity, etc.
