5 IMPORTANT SAFETY INSTRUCTIONS
► To reduce the risk of fire from sparking,
never attempt to start the engine with the
spark plug or boot removed.
► Read and follow recommendations issued
by government authorities (e.g. CCOHS) for
identifying and avoiding the hazards of
combustible gases, liquids, vapors, dusts or
other combustible materials and substan‐
ces.
► Never modify the muffler or spark arresting
screen.
■ If a rotating metal blade strikes a rock or other
hard object, sparks may be created, which can
ignite flammable materials under certain cir‐
cumstances. Flammable materials can include
dry vegetation and brush, particularly when
weather conditions are hot and dry.
► When there is a risk of fire or wildfire, do
not use metal blades around flammable
materials or around dry vegetation or brush.
► Contact your local fire authorities or the
Canadian Forest Service if you have any
question about whether vegetation and
weather conditions are suitable for the use
of a metal blade.
► STIHL does not recommend the use of
metal blades when cutting in rocky areas or
in areas with debris or other objects that
could create sparks.
■ Some STIHL mowing heads have a metal
core. High-speed contact with rock or other
hard objects may create sparks, which can
ignite flammable materials under certain cir‐
cumstances. Flammable materials include dry
vegetation and brush, particularly when
weather conditions are hot and dry.
► When there is a risk of fire or wildfire, do
not use a mowing head with a metal core
around dry vegetation or brush.
► Contact your local fire authorities or the
Canadian Forest Service if you have any
question about whether vegetation and
weather conditions are suitable for the use
of a mowing head with a metal core.
► STIHL does not recommend using a mow‐
ing head with a metal core when cutting in
rocky areas or in areas with debris or other
objects that could create sparks.
■ As soon as the engine is running, it generates
toxic exhaust gases containing chemicals,
such as unburned hydrocarbons (including
benzene) and carbon monoxide, that are
known to cause respiratory problems, cancer,
birth defects, or other reproductive harm.
Some of the gases (e. g. carbon monoxide)
may be colorless and odorless. To reduce the
0458-853-8201-A
risk of serious or fatal injury or illness from
inhaling toxic exhaust gases:
► Start and operate the trimmer /
brushcutter only outdoors in a well
ventilated work area. Never oper‐
ate the trimmer / brushcutter
indoors, in confined spaces or
other poorly ventilated locations.
► If exhaust fumes become concen‐
trated due to insufficient ventila‐
tion, shut off the engine and clear
obstructions from the work area.
Ensure proper ventilation before
resuming work.
■ Use of this trimmer / brushcutter can generate
dust and other substances containing chemi‐
cals known to cause respiratory problems,
cancer, birth defects and other reproductive
harm.
► Consult governmental agencies such as
ECCC, CCOHS and PHAC and other
authoritative sources on hazardous materi‐
als if you are unfamiliar with the risks asso‐
ciated with the particular substances you
are cutting or with which you are working.
■ Inhalation of certain dusts, especially organic
dusts such as mold or pollen, can cause sus‐
ceptible persons to have an allergic or asth‐
matic reaction. Substantial or repeated inhala‐
tion of dust or other airborne contaminants,
especially those with a smaller particle size,
may cause respiratory or other illnesses.
► Control dust at the source where possible.
► To the extent possible, operate the trim‐
mer / brushcutter so that the wind or operat‐
ing process directs any dust, mist or other
particulate matter raised by the trimmer /
brushcutter away from the operator.
► When respirable dust or other particulate
matter cannot be kept at or near back‐
ground levels, always wear a respirator that
is approved by PHAC and rated for work‐
site-specific conditions. Follow the recom‐
mendations of governmental authorities
(e.g., CCOHS/PHAC) and occupational and
trade associations.
■ If the vegetation being cut or the surrounding
ground is coated with a chemical substance,
such as a pesticide or herbicide:
► Read and follow the instructions and warn‐
ings that accompanied the substance coat‐
ing the vegetation or surrounding ground.
