Stihl MS 261 C-M Instruction Manual page 7

During work
Ensure you always have a firm and safe
footing.
In the event of impending danger or in
an emergency, switch off the engine
immediately and push the master control
lever to STOP or †.
The machine is operated by only one
person. There should not be any other
person within the working area.
Never let the machine run unattended.
When the engine is running: Note that
the chain continues to rotate for a short
period after your let go of the throttle
trigger – coasting effect.
Exercise caution with slippery surfaces,
water, snow, ice, steep slopes, uneven
ground or green wood that has just been
stripped of its bark – danger of slipping!
Use caution with tree stumps, roots,
ditches – danger of stumbling!
Do not work alone – keep within calling
distance of others in case help is
needed.
More care and attention than usual are
required when wearing ear protection –
warning sounds (shouts, alarms, etc.)
cannot be heard properly.
Take breaks in due time in order to
prevent tiredness and exhaustion – risk
of accidents!
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.
MS 261 C-M
Your power tool produces
toxic exhaust fumes as
soon as the engine is
running. These gases
may be colorless and
odorless and may contain
unburnt hydrocarbons
and benzene. Never run
the engine indoors or in
poorly ventilated areas,
even if your model is
equipped with a catalytic
converter.
Ensure proper ventilation when working
in trenches, hollows or other confined
areas. Toxic fumes can kill!
If you feel sick, if you 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,
among other things – risk of accident!
Dust (e. g., sawdust), fumes and smoke
produced while using the machine may
be hazardous to health. Wear a dust
mask if dust is generated.
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
–
Ensure that the cutting blades are
–
sharp
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!
To change the saw chain, switch off the
engine – risk of injury!
No smoking when working with or near
the machine - risk of fire! Combustible
fuel vapor may escape from the fuel
system.
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 – refer also to the
section "Before starting". Check the fuel
system for leaks and make sure the
safety devices are working properly.
Never continue using a power tool that is
not in perfect working order. Consult a
servicing dealer if in doubt.
Check for correct idling, so that the saw
chain stops moving when the throttle
trigger is released. Have the machine
repaired by a STIHL servicing dealer if
the saw chain continues to move
nevertheless.
Reactive forces
The most common reactive forces are:
kickback, pushback and pull-in.
Dangers of kickback
Kickback can result in
fatal cuts.
