Stihl MS 391 Safety Manual page 8

English
– Do not allow the top of the guide bar
to become jammed
– Do not twist the guide bar in the cut
Be very careful
– with freely hanging limbs
– with trunks that are under tension
between other trees because they
fell unfavorably
– when working in windbreaks
In these cases, do not use a chain saw –
use a hoist, winch or dragline instead.
Pull out trunks that are lying about and
have been cut free. Whenever possible,
deal with them in open areas.
Deadwood (brittle, rotten or dead wood)
poses a substantial, highly
unpredictable hazard. It is extremely
difficult or even practically impossible to
recognize the danger. Use aids such as
winches or draglines.
Always be especially careful
whenfelling timber near roads,
railway lines, power lines etc. If
necessary, notify police, power
companies or railway authorities.

Holding and guiding the machine
Always hold the chain saw firmly with
both hands: Right hand on the rear
handle – even if you are left-handed. To
ensure reliable control, wrap your
thumbs tightly around the handlebar and
handle.
Sawing
Do not use the starting throttle position
for cutting. Engine speed cannot be
controlled with the throttle trigger in this
position.
Work calmly and methodically – only
with good lighting and visibility. Do not
endanger others – stay alert at all times.
Use the shortest possible guide bar: The
chain, guide bar and chain sprocket
must match each other and your saw.
Make certain that all parts of your body
are well clear of the extended range of
travel of the saw chain.
Always pull the saw out of the cut with
the saw chain running.
Use the chain saw only for sawing – not
for prying or shoveling away limbs or
roots.
Do not underbuck freely hanging limbs.
Be careful when cutting shattered wood
– risk of injury from slivers being
caught and thrown in your direction!
Make sure your saw does not touch any
foreign materials: Stones, nails, etc. may
be flung off and damage the saw chain –
the saw may kick back unexpectedly.
