Sharpening The Saw Chain - Makita HCU01 Manual De Instrucciones

(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;
•
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 -1/3 of
the trunk diameter. Do not make the scarf too
large. Then make the diagonal cut.
− 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.
− 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.
