Stihl BT 131 Instruction Manual page 7

Do not drop-start the engine – start it as
described in the instructions for use.
Check idle speed setting: The drilling
tool must not rotate when the engine is
idling with the throttle trigger released.
Keep easily combustible materials (e.g.,
wood chips, bark, dry grass, fuel) away
from hot exhaust gases and the hot
muffler surface – risk of fire!
Holding and guiding the machine
Always hold the unit firmly with both
hands on the handles.
Ensure you always have a firm and safe
footing – drill brake on left thigh.
Firmly grasp the handles with the
thumbs, left hand on control handle.
BT 131
While working
Make sure you always have good
balance and secure footing.
In the event of impending danger or in
an emergency, switch off the engine
immediately by pressing the stop switch.
Do not allow any other persons in the
work area. Keep well away from other
people – risk of accidents!
Check for correct idling, so that the
auger stops turning when the throttle
trigger is released.
Check and correct the idle speed setting
at regular intervals. If the drilling tool
continues to rotate when the engine is
idling, have the machine checked by
your servicing dealer. STIHL
recommends STIHL dealers.
Take special care in slippery conditions
– dampness, snow, ice, on slopes or
uneven ground.
Watch out for obstacles: tree stumps,
roots – risk of tripping or stumbling!
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Take breaks when you start getting tired
or feeling fatigue – risk of accidents!
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Proceed with caution, do not put
others in danger.
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 run the engine
indoors or in poorly venti-
lated locations, even if
your model is equipped
with a catalytic converter.
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. This reduces the risk of
serious or fatal injury from breathing
toxic fumes.
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.
Dust, fumes and smoke produced while
working may be hazardous to your
health. Wear respiratory protection in
case of heavy dust or smoke emission.
