LIMBING
Limbing is the process of removing the branches
from a fallen tree. Check the direction in which a
branch will bend before cutting it. Always cut on the
opposite side to the bending direction so that the
guide bar is not pinched in the cut. For large limbs
that cannot be removed in one cut, make an initial
cut from the bent side and finish by sawing from
the opposite direction (Fig.19). Do not remove
limbs that are supporting the fallen tree on the
ground until the tree has been cut into lengths.
WARNING. Always keep a well balanced
stance. Do not stand on the log. Be alert
to the fact that the log may roll over.
When working on a slope, always stand
on the uphill side of the log.
PRUNING
Pruning is the removal of a limb or branch from a
standing tree.
WARNING. Do not use an unstable
foothold or ladder. Do not overreach. Do
not saw above shoulder height. Always
use both hands to hold the saw. First cut
up from the bottom and finish down from
the top, Fig.14.
FELLING
Felling is the term for cutting down a tree. Small
trees up to 6-7 inches (15-18cm) in diameter are
usually cut in a single cut. Larger trees require
notch cuts. Notch cuts determine the direction the
tree will fall.
WARNING. Do NOT fell trees unless you
have received the appropriate training.
A retreat path (Fig.15- A) should be
planned and cleared as necessary
before cuts are started. The retreat path
should extend back and diagonally to the
rear of the expected line of fall, as
illustrated.
NOTE: Direction of fall (Fig.21-B) is
controlled by the notching cut. Before
any cuts are made, consider the location
of larger branches and natural lean of
the tree to determine the way the tree
will fall.
