4. Clean up the working area and the area onto which
the tree will fall and clearly mark an escape route
in case the tree does not fall in the expected
direction. The security distance should be at least
twice that of the height of the tree.
5. Cut some branches first. Start with the bottom
branches that could difficult your work. Remember
not to cut those branches above shoulder level.
6. So as to guide the fall of the tree, do a guided cut
(B). To do this guided cut, cut at a 60 angle until
you cut into the log some 25% of the width of the
trunk. This cut must be done on the side to which
the tree will fall (E). After this, do a further 35 cut
that ends up matching the 60 cut, thus obtaining a
95 angle as shown in the attached diagram.
7. Start a horizontal cut © in the opposite side some
3 cm above the interior angle of the guided cut (B).
8. When you have cut 25% through the trunk, place a
wedge to avoid the tree inclining on the opposite
side to that where you want the tree to fall to. It
also avoids the bar being imprisoned.
9. Carry on the cut © until you reach some 3cm from
the guided cut. We must leave this space that will
act as a hinge which will ensure that the tree falls
in the expected direction.
10. The tree will fall in direction E.
If the tree does not fall, force its fall by pushing
the wedge further into the trunk of the tree.
The moment the tree starts to fall, move away
backwards and to one side to maintain an adeqaute
security distance (a bigger distance to that of the
height of the tree being cut.) It is fundamental to move
away once the tree is falling, as when the tree starts
touching other objects and the floor, branches will
break and could be propelled towards the end user.
When felling a tree, always warn everybody who is in
the vicinity before starting and also warn everybody
before doing the horizontal cut and the tree starts
falling.
Ensure you are in a stable position and never lean on
the tree being felled. If you work on an incline, place
yourself on the top incline so as to avoid the tree
rolling towards you once it has been cut.
Follow all the security instructions included in
this manual so as to avoid the kick back of
the machine.
7.3.2. CUTTING A TRUNK PLACED ON THE GROUND
When a trunk is fully
placed on the ground,
cut firstly halfway from
the top end, then turn the trunk halfway and cut the
rest.
If the trunk is leaning on two sides (B zone) you must
first cut the top end halfway through (1) and then
cut the rest from below (2). This way you will avoid
that the internal trunk tension closes in on the cut,
blocking the chain and the chainsaw bar.
