Stihl BR 450 C-EF Instruction Manual page 10

English
Recommended working technique to
minimize noise:
Operate your power tool at
–
reasonable times only – not early in
the morning, late at night or during
midday rest periods when people
could be disturbed. Observe local
rest periods. Normal
recommendation for professional
use on weekdays: 9:00hrs to
12:00hrs and 15:00hrs to 17:00hrs.
Be considerate of neighbors at
weekends.
Fewer engines mean less noise.
–
Where possible, do not run more
than one power tool at any time.
Operate blowers at the lowest
–
engine speed necessary to
accomplish the task.
Check your blower before starting
–
work. Pay special attention to the
muffler, air intakes and air filter.
Operate and start your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.

WARNING
As soon as the engine is
running, this product gen -
erates toxic exhaust
fumes containing chemi -
cals, such as unburned
hydrocarbons (including
benzene) and carbon
monoxide, that are
known to cause respira -
tory problems, cancer,
birth defects, or other
reproductive harm. Some
of the gases (e.g. carbon
monoxide) may be color -
less and odorless. To
reduce the risk of serious
or fatal injury/illness from
inhaling toxic fumes,
never run the machine
indoors or in poorly venti -
lated locations. If exhaust
fumes become concen -
trated due to insufficient
ventilation, clear obstruc -
tions from work area to
permit proper ventilation
before proceeding and/or
take frequent breaks to
allow fumes to dissipate
before they become
concentrated.
WARNING
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. This includes wood dust,
especially from hardwoods, but also
from some softwoods such as Western
Red Cedar. Control dust at the source
where possible. Use good work
practices, such as operating the unit so
that the wind or operating process
directs any dust raised by the power tool
away from the operator. Follow the
recommendations of
EPA/OSHA/NIOSH and occupational
and trade associations with respect to
dust ("particulate matter"). When the
inhalation of dust cannot be
substantially controlled, i.e., kept at or
near the ambient (background) level, the
operator and any bystanders should
wear a respirator approved by
NIOSH/MSHA for the type of dust
encountered.
WARNING
If the substance being blown is a
commercial substance, review the
material safety data sheet for that
substance and / or consult the material
manufacturer / supplier. The state of
California and some other authorities,
for instance, have published lists of
substances known to cause cancer,
reproductive toxicity, etc.
WARNING
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. If you have any reason to
believe that you might be blowing or
