6.6 FORESTRY WORK
6.6.1 Delimbing a tree
Make sure there is nothing or nobody
in the area where the branches will fall.
For pruning high up using a rope
and a belt harness, carefully follow
the instructions under par. 6.7.

from top to bottom, as shown in (Fig. 23.B).
6.6.2 Felling a tree
IMPORTANT Where two or more persons
are working together on felling and bucking
operations, such operations must be performed
in separate areas at a distance from each
other of at least 2.5 times the height of the tree
being felled. Do not fell trees if this involves
risks of injuring people, coming into contact
with a power line or causing any form of
damage. If the tree should come into contact
with a main power line, report the incident
immediately to the network provider.
Before commencing the felling operations:
–
inclination of the tree, the part where the
branches are larger and the wind direction,
–
– clear the area around the tree and
– plan obstacle-free escape routes at a 45°
the fall (Fig. 24) which allow the operator
to escape to a safe zone, about 2.5 times
the height of the tree being felled;
– Stand uphill of the land onto which the tree

1. Stand to the right of the tree,
behind the chainsaw.
2. Saw a horizontal face notch to 1/3 of the
diameter of the tree, perpendicular to the
direction in which it will fall (Fig. 25.A).
•

5 cm higher than the horizontal
face notch (Fig. 26.B).
2.
wood to act as a "hinge” (Fig. 26.C).
The hinge wood will prevent the tree
from twisting and falling in the wrong
direction. Do not cut through the hinge.

use some wooden, plastic or aluminium
wedges (Fig. 27.D) to open the cut. Force
hitting the wedges with a sledge hammer.
5.

6.6.3 Limbing tree branches
Limbing means removing the
branches from a felled tree.
Be careful of where the branches are
lying on the ground, the risk of them being
under tension, the direction the branch may
