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.
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!
Country-specific legislation on felling
technique must be complied with during
felling work.
Cutting
Do not operate your saw with the
starting throttle lock engaged. Engine
speed cannot be controlled with the
throttle trigger in this position.
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Ensure you do not endanger
others – stay alert at all times.
First-time users are advised to practice
cutting logs on a sawhorse – see "When
cutting small logs".
Use the shortest possible guide bar: The
chain, guide bar and chain sprocket
must match each other and your saw.
