Use your machine only in the areas specified in
the instruction manual of the power tool attach‐
ment.
Your power tool produces toxic
exhaust fumes as soon as the engine
is running. These fumes may be col‐
orless and odorless and contain
unburned hydrocarbons and benzol.
Never run the engine indoors or in
poorly ventilated locations, even if
your model is equipped with a cata‐
lytic converter.
To reduce the risk of serious or fatal injury from
breathing toxic fumes, ensure proper ventilation
when working in trenches, hollows or other con‐
fined locations.
To reduce the risk of accidents, stop work imme‐
diately in the event of nausea, headache, visual
disturbances (e.g. reduced field of vision), prob‐
lems with hearing, dizziness, deterioration in abil‐
ity to concentrate. Apart from other possibilities,
these symptoms may be caused by an exces‐
sively high concentration of exhaust gases in the
work area.
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. Note
that combustible fuel vapor may escape from the
fuel system.
The dusts, vapor and smoke produced during
operation may be dangerous to health. If the
work area is very dusty or smoky, wear a respira‐
tor.
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 in particular for leaks and
make sure the safety devices are working prop‐
erly. Do not continue operating your power tool if
it is damaged. In case of doubt, consult your
servicing dealer.
Do not operate your power tool in the starting
throttle position – engine speed cannot be con‐
trolled in this position.
Before leaving the power tool unattended: Shut
off the engine.
To reduce the risk of unintentional engine start
and injury, always shut off the engine and
remove the spark plug boot before changing the
attachment.
3.8
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 cir‐
culation (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.
3.9
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 per‐
formed by a servicing dealer.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized 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.
To reduce the risk of injury, always shut off the
engine before carrying out any maintenance or
repairs or cleaning the machine. – Exception:
Carburetor and idle speed adjustments.
