Before tackling the task, follow these steps:
1. Decide the direction the tree will fall (A). Note the
inclination of the tree, the length of its branches
and remember that they may change direction in
the fall.
2. Make sure there are no other trees, branches
or obstacles that may hit the tree as it falls.
3. Check which will be the final position of the tree to
be cut.
5. Perform an initial limbing. Start with the lower
branches that may make it difficult to work.
Remember that you should not cut branches that
over shoulder height.
6. To guide the fall of the tree make a cut Guide
(B). To make this guiding cut, cut at a 60 degree
angle up to the width of the tree (¼ d) quarter by
the side of the direction in which want tree to fall
(E) and then a cut of 35° that reaches until the
end of the cutting 60° so that you get a discharge
at 90° as shown in the following figure.
Recommendation: Before moving on to the next
stage, fill in fuel and oil deposits of the saw to avoid
the machine stopping unexpectedly in the following
operations:
4. Clear the area around the
drop zone, make sure that
you can work in a stable
position and set an easy
getaway that allows you to
run away in case the tree
does not fall in the expected
direction. The safety
distance must be at least
twice the height of the tree.
7. Start a horizontal cut (C) on the opposite side, 3 cm
above the inside of the cutting angle Guide (B).
8. When you have cut a ¼ of the tree's diameter, stop
cutting and insert a wedge at the beginning of
the cut to prevent axle tilt in the opposite desired
direction, the cut is closed and the chainsaw rod is
pinched.
9. Continue cutting (C) until you reach about 3 cm of
the cutting Guide. We will never cut to the guide
cut in order to leave a bit of wood that will take the
role of a hinge and will lead to the fall of the tree in
the right direction.
10. The tree will fall in the "E" direction.
If the tree does not fall, force the fall by introducing
more wedge into the tree.
In the moment that the tree begins to fall, move away
in a sideways and backwards direction with regard to
the direction of the fall of the tree until it is at a safe
distance (distance greater than the height of the tree
being cut).
It is essential to move away from the tree falling
because at moment the tree starts to hit the ground,
free flying branches (or parts of them) are split
backwards and sideways and hit or cut the user.
When you are going to bring a tree down always notify
all persons who are around before starting and again
