Stihl SR 430 Instruction Manual page 10

English
As soon as the engine is
running, the power
machine generates toxic
exhaust gas. These
gases may be odorless
and invisible and may
contain unburned hydro-
carbons and benzene.
Never work with the
machine in closed or
poorly ventilated rooms.
To reduce the risk of serious or fatal
injury from breathing toxic fumes,
ensure proper ventilation when working
in trenches, hollows or other confined
locations.
Stop work immediately if you start
suffering from nausea, headaches,
impaired vision (e.g. your field of vision
gets smaller), impaired hearing,
dizziness, or impaired concentration –
these symptoms may possibly be the
result of too-high exhaust gas
concentration – Risk of accidents!
Operate your power tool so that it
produces a minimum of noise and
emissions – do not run the engine
unnecessarily, accelerate the engine
only when working.
To reduce the risk of fire, do not smoke
while operating or standing near your
power tool. Combustible fuel vapor may
escape from the fuel system.
If your power tool is subjected to
unusually high loads for which it was not
designed (e.g. heavy impact or a fall),
always check that it is in good condition
before continuing work – see also
"Before Starting". Check the fuel system
for leaks and make sure the safety
devices are working properly. Do not

continue operating your power tool if it is
damaged. In case of doubt, contact a
dealer.
After finishing work
Close the valve lever and, on SR 450
only, the metering lever
Always shut off the engine before taking
the power tool off your back.
After finishing work, put the power tool
down on a level, non-flammable surface.
Do not place the machine near easily
flammable materials (e.g. wood chips,
bark, dry grass, fuel) – risk of fire!
Check all parts of the power tool for
leaks.
After finishing work, thoroughly clean the
power tool and wash your hands, face
and, if necessary, your clothes.
Keep other persons and animals away
from the areas that have been sprayed
and do not walk on them until the plant
protection chemical has dried.
Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
Hand protection (wearing warm
–
gloves)
Work breaks
–
The period of usage is shortened by:
Any personal tendency to suffer
–
from poor circulation (symptoms:
frequently cold fingers, tingling
sensations).
Low outside temperatures.
–
The force with which the handles
–
are held (a tight grip restricts
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and are supplied with
the necessary technical information.
Only use high-quality replacement parts
in order to avoid the risk of accidents
and damage to the machine. If you have
any questions in this respect, consult a
servicing dealer.
STIHL recommends the use of genuine
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
