Catalytic Converter - Brother BHL 3040 Operating Instructions Manual

Warning!
As soon as the engine is running, this prod-
uct generates toxic exhaust fumes containing
chemicals (such as unburned hydrocarbons
and carbon monoxide) known to cause res-
piratory problems, cancer, birth defects, or
other reproductive harm. Some of the gases
(e.g. carbon monoxide) may be colorless and
odorless. To reduce the risk of serious or fatal
injury/illness from inhaling toxic fumes, never
run the machine indoors or in poorly ventilated
locations.
The muffler and other parts of the engine (e.g. fins of the
cylinder, spark plug) become hot during operation and re-
main hot for a while after stopping the engine.
To reduce risk of burns do not touch the muffler and other
parts while they are hot.
To reduce the risk of fire and burn injury, keep the area
around the muffler clean. Remove excess lubricant and
all debris such as pine needles, branches or leaves. Let
the engine cool down sitting on concrete, metal, bare
ground or solid wood (e.g. the trunk of a felled tree) away
from any combustible substances.
Never modify your muffler. The muffler could be damaged
and cause an increase in heat radiation or sparks, there-
by increasing the risk of fire and burn injury. You may also
permanently damage the engine.

Catalytic converter

Warning!
The engine is equiped with a catalytic con-
verter, 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, 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 combustible materials while it is still hot.
An improperly mounted or damaged cylinder housing or
a damaged / deformed muffler shell may interfere with
the cooling process of the catalytic converter. To reduce
the risk of fire or burn injury, do not continue work with a
damaged or improperly mounted cylinder housing or a
damaged/ deformed muffler shell.
Your catalytic converter is furnished with screens de-
signed 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 serv-
ice or maintenance.
3 THE POLE HEDGE TRIMMER
Transporting the Pole Hedge Trimmer
Warning!
To reduce the risk of injury from blade contact, never car-
ry or transport your tool with the cutter blades moving.
It may be carried only in a horizontal position. Grip the
shaft in a manner that the machine is balanced horizon-
tally. Keep the hot muffler away from your body. Keep the
cutting attachment behind you.
Always switch off the engine and fit the scabbard over
the cutter blades before transporting the power tool over
long distances. When transporting it in a vehicle, properly
secure it to prevent turnover, fuel spillage and damage
to the unit.
On machines with an adjustable cutter bar: Make sure the
cutter bar is secured in position.
Before Starting
Warning!
Always check your attachment for proper condition and
operation before starting. Never attempt to modify the
controls or safety devices.
Never use a engine that is damaged or not properly main-
tained. Keep the handles clean and dry at all times; it is
particularly important to keep them free of moisture, pitch,
oil, grease or resin in order for you tomaintain a firm grip
and properly control your engine.
The cutting tool must be properly tightened and in safe
operating condition. Inspect for loose parts (nuts, screws,
etc.) and for cracked, bent, warped or damaged blades.
Regularly check the condition and tightness of the cutter
blades – with the engine stopped!
Replace damaged cutter blades before using the power
tool. Always keep blades sharp.
We recommend that you always spray the cutter blades
with resin solvent before starting work - with the engine
stopped!
Adjust carrying harness and hand grip to suit your size
before starting work.
Starting
On machines with an adjustable cutter bar: Secure the
cutter bar in the starting position as described in the
GB-5
