uses. See the "Maintenance, Repair and
Storing" section of these Safety
Precautions. Remember that the risk of
a brush or forest fire is greater in hot or
dry conditions.
WARNING
Some STIHL power tools
are equipped with a cata-
lytic converter, which is
designed to reduce the
exhaust emissions of the
engine by a chemical pro-
cess in the muffler. Due
to this process, the muf-
fler does not cool down
as rapidly as conven-
tional mufflers when the
engine returns to idle or
is shut off. To reduce the
risk of fire and burn inju-
ries when using a
catalytic converter,
always set your power
tool down in the upright
position and never locate
it where the muffler is
near dry brush, grass,
wood chips or other com-
bustible materials while it
is still hot.
MAINTENANCE, REPAIR AND
STORAGE
WARNING
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
BR 450, BR 450 C
Strictly follow the maintenance and
repair instructions in the appropriate
section in this instruction manual.
Please refer to the maintenance chart in
this instruction manual.
WARNING
Always stop the engine and make sure
that the fan is stopped before doing any
maintenance or repair work or cleaning
the power tool. Do not attempt any
maintenance or repair work not
described in this instruction manual.
Have such work performed by your
STIHL servicing dealer only.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
WARNING
Use the specified spark plug and make
sure it and the ignition lead are always
clean and in good condition. Always
press spark plug boot snugly onto spark
plug terminal of the proper size. A loose
connection between spark plug terminal
and the ignition wire connector in the
boot may create arcing that could ignite
combustible fumes and cause a fire.
Keep spark plug clean, and make sure
ignition lead is in good condition. Do not
use a spark plug with a detachable SAE
adapter terminal. Arcing may occur that
could ignite combustible fumes and
cause a fire. This can result in serious
injuries or damage to property.
WARNING
Never test the ignition system with the
boot removed from the spark plug or
with a removed spark plug, since
uncontained sparking may cause a fire.
WARNING
Do not operate your power tool if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Your muffler is equipped with a spark-
arresting screen to reduce the risk of
fire; never operate your power tool if the
screen is missing, damaged or clogged.
Remember that the risk of a brush or
forest fire is greater in hot or dry
weather.
In California, it is a violation of § 4442 or
§ 4443 of the Public Resources Code to
use or operate gasoline-powered tools
on forest-covered, brush-covered or
grass-covered land unless the engine's
exhaust system is equipped with a
complying spark arrester that is
maintained in effective working order.
The owner/operator of this product is
responsible for properly maintaining the
spark arrester. Other states or
governmental entities/agencies, such as
the U.S. Forest Service, may have
similar requirements. Contact your local
fire agency or forest service for the laws
or regulations relating to fire protection
requirements.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
