tree being cut back should be at least twice the
height of the tree being felled (Fig. 16). When
felling trees, care must be taken to ensure that no
other persons are endangered, no power supply
lines are hit and no material damage is caused
to equipment or property. In the event that a tree
comes into contact with a power supply line, he
responsible power supply company should be
informed immediately. When working with the saw
on a slope, the operator of the chainsaw must
be standing at a higher point on the slope than
the tree being felled, as the tree will roll or slip
downhill once it has been felled (Fig. 17).
Before felling the tree you must fi rst plan and if
necessary clear an escape route. This escape
route must lead away diagonally in the opposite
direction to the expected fall direction – this can
be seen in Fig. 18 (A= danger zone, B= direction
of fall, C= escape zone).
Before felling the tree you must take into account
the natural inclination of the tree, the location of
larger branches and the wind direction, as this will
help you to correctly determine the direction in
which the tree will fall.
Dirt, stones, loose bark, nails, staples and wire
must be removed from the tree.
Making the felling notch (Fig. 19)
Cut a notch (A) at right angles to the fall direction
to a depth of 1/3 of the tree diameter as shown
in Fig. 19. First make the lower horizontal felling
notch (1). This prevents the saw chain or the
guide rail from becoming trapped when the
second felling notch is made.
Making the felling cut (Fig. 19)
The felling cut should be positioned at least 50
mm above the horizontal felling notch. Make the
felling cut (B) parallel to the horizontal felling
notch. The felling cut should be cut to a depth
which leaves a thin strip (felling hinge strip) (D)
which can act as a hinge. This strip prevents
the tree from rotating and falling in the wrong
direction. Do not cut through the strip. When the
felling cut gets close to the strip the tree should
start to fall. If it becomes clear that the tree may
well fall in a diff erent direction to the desired fall
direction (C) or it starts to lean back and traps
the saw chain, interrupt the felling cut and insert
wedges made of wood, plastic or aluminum to
open out the cut and control the lean of the tree
until it leans in the required direction.
When the tree starts to fall, remove the chainsaw
from the cut, switch it off , place it on the ground

and exit the danger zone via the planned escape
route. Watch out for falling branches and take
care not to trip.
Removing branches
Here we are talking about removing branches
from the felled tree. When removing branches,
leave any downward facing branches which are
supporting the tree until the trunk of the tree
has been cut up. Smaller branches should be
removed as shown in Fig. 20 (A= cutting direction
when removing branches, B= keep away from
the ground! Supporting branches should be left
until the trunk is cut up) in a single cut from the
bottom to the top. Any branches which are under
tension should be cut from the bottom to the top
to prevent the saw from becoming trapped.
Cutting the tree trunk into lengths
Here we are looking at the process of cutting
the felled tree into sections. Make sure you have
a sure footing and distribute your body weight
evenly onto both feet. If possible the trunk should
be underlaid and supported with branches,
beams or wedges. For easy cutting follow the
simple instructions below.
If the full length of the tree trunk is evenly
supported as shown in Fig. 21 then proceed by
cutting from the top down. Take care not to cut
into the ground in the process.
If the weight of the tree trunk is resting on one end
as shown in Fig. 22, fi rst cut through 1/3 of the
trunk diameter from the underside (A) in order to
prevent it from splintering. Make the second cut
from the top (2/3 of the diameter) to the height of
the fi rst cut (B) (this prevents the chainsaw from
being trapped).
If the weight of the tree trunk is resting on both
ends as shown in Fig. 23, fi rst cut through 1/3
of the trunk diameter from the top (A) in order
to prevent it from splintering. Make the second
cut from underneath (2/3 of the diameter) to
the height of the fi rst cut (B) (this prevents the
chainsaw from being trapped).
When working with the saw on a slope, always
position yourself at a higher point on the slope
above the tree as shown in Fig. 15. In order to
retain full control at the moment when the cut
goes through, reduce pressure towards the end
of the cut without releasing your fi rm grip on the
handles of the chainsaw. Take care to ensure that
the chainsaw does not touch the ground. After
completing the cut, wait for the chain saw to come
to a standstill before removing the chainsaw.
