Limbing
Limbing is the designation for the sawing
off of branches and boughs from a felled
tree.
Many accidents occur during the
removal of branches. Never cut tree
limbs when you are standing on the
log. Keep the spring-back area in
mind if branches are under tension.
• Do not remove support branches until
after the sawing off.
• Branches under tension must be sawed
from below to above, in order to pre-
vent jamming of the chainsaw.
When working on thicker branches,
use the same technique as when you
are sawing up a felled trunk.
• Work to the left of the log and as near
as possible to the electric chainsaw. As
far as possible, the weight of the saw
should rest on the log.
• Change position to saw off branches
on the other side of the trunk.
• Branches sticking out are cut off sepa-
rately.(see
).
Felling trees
A lot of experience is nec-
essary in felling trees. Cut
down trees only when you
can safely handle the electric
chainsaw. In no case should
you use the electric chainsaw
if you feel unsure about any-
thing.
• Ensure that no people or animals are in
the field of action. The safety distance
between the tree to be felled and the
nearest-located workplace must be 2 ½
tree lengths.
• Note the felling direction:
The user must be able to move safely
near the felled tree, to saw off the tree
easily and remove branches.It is to be
avoided that the felled tree snags itself
on another tree. Note the natural felling
direction, which is dependent on the
slope and curvature characteristic of
the tree, wind direction and the number
of branches.
• In the case of sloping ground, stand
above the tree to be felled.
• Small trees, with a diameter of 15-18
cm, can usually be sawn off with one
cut.
• In case of trees with a larger diameter,
a notched cut and a back cut must be
implemented (see diagram).
• If cutting and felling is being carried
out by two or more persons simultane-
ously, the distance between the felling
and cutting persons must be at least
twice the height of the tree to be fellled.
When felling trees, ensure that no other
persons are subject to hazards and that
no material damage is caused. If a tree
should come into contact with a power
line, the supply company must be in-
formed immediately.
• Dirt, stones, loose bark, nails, clips and
wires must be removed from the tree.
Do not fell any trees when
a strong or changing wind
is blowing, if the danger of
property damage exists or if
the tree could fall on electric
wires.
Immediately after termination of
the sawing procedure, remove the
ear protection so that you can hear
hooter and alarm signals.
