Pushback (B)
When the chain on the top of the bar –
underbucking – is suddenly pinched,
caught or encounters a foreign object in
the wood, the chain saw may suddenly
be driven straight back toward the
operator – to avoid this:
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.
MS 261 C-M
Always be especially careful when
felling timber near roads, railway lines,
power lines etc. If necessary, notify
police, power companies or railway
authorities.
Sawing
Do not use the starting throttle position
B
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.
On slopes, always stand above or to the
side of the trunk or felled tree. Watch out
for rolling trunks.
When working above ground level:
Always use a lift bucket
–
Never use the machine while
–
standing on a ladder or in a tree
Never use the machine in unsteady
–
locations
Never cut above shoulder height
–
Never use the machine with one
–
hand
Begin cutting with the saw at full throttle
and engage the bumper spike – then
saw.
