(3) The base of the trunk | is | free of | foreign | |
| objects, roots and ranches; |
|
| |
(4) No persons or objects | are | present | over a | |
| distance of 2 1/2 tree lengths in the direction | |||
| in which the tree will fall. |
|
|
|
− Consider the following with respect to each tree: | ||||
• | Direction of lean; |
|
|
|
• | Loose or dry branches; |
|
|
|
• | Height of the tree; |
|
|
|
• | Natural overhang; |
|
|
|
−Stand to the side of the falling tree. Keep an area clear to the rear of the falling tree up to an angle of 45 ° either side of the tree axis (refer to the " felling area " figure). Pay attention to falling branches.
−An escape path should be planned and cleared as necessary before cuts are started. The escape path should extend back and diagonally to the rear of the expected line of fall as illustrated in figure.
• | Whether or not the tree is rotten. |
− Consider the wind speed and direction. Do not | |
carry out felling work if the wind is gusting strongly. | |
− Trimming of root swellings: Begin with the largest | |
swellings. Make the vertical cut first, then the | |
horizontal cut. | |

−Cut a scarf: The scarf determines the direction in which the tree will fall, and guides it. It is made on the side towards which the tree is to fall. Cut the scarf as close to the ground as possible. First make the horizontal cut to a depth of 1/5
−Cut any corrections to the scarf across its entire width.
006923
−Make the back cut a little higher than the base cut of the scarf. The back cut must be exactly horizontal. Leave approximately 1/10 of the trunk diameter between the back cut and the scarf.
The wood fibers in the uncut trunk portion act as a hinge. Do not cut right through the fibers under any circumstances, as the tree will otherwise fall unchecked. Insert wedges into the back cut in time.
−Only plastic or aluminum wedges may be used to keep the back cut open. The use of iron wedges is prohibited.
