Examine the saw chain periodically at
short intervals and as soon as you note
any tangible changes:
–
Switch off the engine; wait until the
saw chain is stationary
–
Check condition and secure fitting
–
Check sharpness
Never touch the saw chain when the
engine is running. If the saw chain
becomes jammed by an object, switch
off the engine immediately before
attempting to remove the object – risk of
injury!
Always turn off the engine before leaving
the machine unattended.
To change the saw chain, switch off the
engine. Risk of injury from the motor
starting unintentionally!
Keep easily combustible materials
(e. g., wood chips, bark, dry grass, fuel)
away from hot exhaust gases and hot
mufflers – risk of fire! Mufflers with
catalytic converters can become
especially hot.
Never work without chain lubrication –
monitor the oil level in the oil tank. Stop
work immediately if the oil level in the oil
tank is too low and top up with chain oil
– see also "Topping up with chain oil"
and "Check chain lubrication".
If the machine 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 work".
Check the fuel system for leaks and
make sure the safety devices are
working properly. Never continue using
a machine that is not in perfect working
order. In case of doubt, have the unit
checked by your servicing dealer.
Check for correct idling, so that the saw
chain stops moving when the throttle
trigger is released. Check the idle setting
regularly and correct when possible.
Have the machine repaired by a STIHL
servicing dealer if the saw chain still
continues to move during idling.
Ensure proper ventilation when working
in trenches, hollows or other confined
locations – risk of fatal injury from
breathing toxic fumes!
If you feel sick, have a headache, vision
problems (e. g., your field of vision gets
smaller), hearing problems, dizziness or
inability to concentrate, stop work
immediately. Such symptoms may be
caused by an excessively high
concentration of exhaust emissions –
risk of accident!
After finishing work
Switch off the motor, engage the chain
brake and attach the chain scabbard.
Storage
When the machine is not in use, it
should be stored in such a way that no-
one is endangered. Secure the machine
against unauthorised use.
Store the machine in a safe, dry room.
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.
The chain saw produces
poisonous exhaust gases
as soon as the engine
starts. These gases may
be colourless and odour
-
less and may contain
unburnt hydrocarbons
and benzene. Never work
with the machine indoors
or in poorly ventilated
areas, even if your
machine is equipped with
a catalytic converter.
