Cutting down trees
WARNING!
Carefully read and follow all instructions before starting work!
Logging
1. Determine the direction of the fall according to the wind, the angle
of the tree, the direction of growth of heavy branches and similar
factors.
2. The surrounding area of the tree should be cleared to provide solid
standing point the easiest escape route.
3. Cut a triangle shape in the size of one-third, on the side where the
tree will fall. (C1)
4. Make a horizontal cut on the opposite side and slightly higher than
the lower side of the triangular shape. (C1)
NOTE: The horizontal cut should be precise and levelled. When felling,
about 1/10 of the diameter of the
trunk must remain as a break-off edge. Do not cut away the break-off
edge as it serves as a hinge so that the
tree does not fall uncontrollably.
5. When the tree begins to fall, turn off the chain saw and start to pull
move away from the tree.
WARNING! Alert others about the danger when the tree is falling.

· Check the direction of the bending force of the trunk before
work.
Always finish cutting on the opposite side of the trunk direction.
