cuts determine the direction the tree wili
fall.
FELLING A TREE:
WARNING
A retreat path (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 iliustrated
in Figure 5-2A,
CAUTION
If felling a tree on sloping ground, the
chain saw operator shouid keep on the
uphili side of the terrain, as the tree is
likely to roll or slide downhill after it is
felled.
NOTE: Direction of fall (B) is controlled
by the notching cut. Before any cuts are
made, consider the location of large
rbranches and natural lean of the tree
to determine the way the tree will fall.
from the other side of the tree and 1.5”-

notch (C) (Figure 5-28).

WARNING
Do not cut down a tree during high or
changing winds or if there is a danger to
property.Consuit a tree professional. Do
not cut down a tree if there is a danger
of striking utility wires; notify the utility
company before making any cuts.
GENERAL GUIDELINES FOR
FELLING TREES:
Normally felling consists of two(2) main
cutting operations, notching (C) and
making the felling cut (D). Start making
the upper notch cut (C) on the side of
the tree facing the felling direction (E).
Be sure you don’t make the lower cut
too deep into the trunk.
The notch (C) should be deep enough
to create a hinge (F) of sufficient width
and strength.The notch should be wide
enough to direct the fall of the tree for
as long as possible.
WARNING
Never walk in front of a tree that has
been notched. Make the felling cut (D)
Never saw completely through the
trunk. Always leave a hinge. The hinge
guides the tree.if the trunk is completely
cut through, control over the felling
direction is lost.
Insert a wedge or felling lever in the cut
well before the tree becomes unstable
and starts to move,This will prevent the
guide bar from binding in the felling cut
if you have misjudged the falling direct­
ion. Make sure no bystanders have
entered the range of the falling tree
before you push it over,
WARNING
Before making the final cut, always rec­
heck the area for bystanders, animats
or obstacles,
FELLING CUT:
1. Use wooden or plastic wedges (G)
to prevent binding the bar or chain
(FI) in the cut.Wedges also control
felling (Figure 5-2C).
2. When diameter of wood being cut is
greater than the bar length, make
two(2) cuts as shown (Figure 5-2D).
WARNING
As the felling cut gets close to the
hinge, the tree should begin to fall.
When tree begins to fall, remove saw
from cut, stop engine, put chain saw
down, and leave area along retreat path
(Figure 5-2A),
