felled, as the tree will roll or slip downhill once it has been felled (Fig.
15).
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 op-
posite direction to the expected fall direction – this can be seen in Fig.
16 (A= danger zone, B= direction of fall, C= escape zone).
Before felling the tree you must take into account the natural inclinati-
on 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. 17)
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. 17. First make the lower horizontal
felling notch (1). This prevents the saw chain or the guide rail from be-
coming trapped when the second felling notch is made.
Making the felling cut (Fig. 17)
GB
The felling cut should be positioned at least 50 mm above the hori-
zontal 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.
