be drawn forward toward the log – to
avoid this, engage the bumper spike
firmly in the wood.
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 unfavourably
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.

Dead wood (brittle, rotten or dead wood)
poses a significant, highly unpredictable
hazard. It is extremely difficult or even
practically impossible to recognise the
danger. Use aids such as winches or
draglines.
When felling close to roads, rail lines,
power lines, etc., work with particular
care. If necessary, notify police, power
companies or railway authorities.

Working Techniques

Sawing and felling work, including all
related work (plunge cutting, limbing,
etc.) may only be carried out by persons
who have been specially trained and
instructed. Persons who are not
experienced chain saw users should not
carry out any such work – increased risk
of accidents!
Gasoline chain saws are more suitable
for felling and limbing than cordless
chain saws.
The cordless chain saw is not suitable
for cutting in blowdown areas and must
not be used for such work.
If, however, a tree is to be felled and
limbed with a cordless chain saw, it is
imperative to observe the country-
specific legislation on felling technique.
Sawing
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Do not endanger others – stay
alert at all times.
It is advisable for first-time users to
practice cutting logs on a sawbuck – see
"Sawing thin wood".
Use the shortest possible guide bar: The
chain, guide bar and chain sprocket
must match each other and your saw.
