c. Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator. d. Check for broken or dead branches which can fall on you while cutting. e. Make sure there is enough room for the tree to fall. Maintain a distance of 2 1/2 tree lengths from the nearest person or other objects. Engine noise can drown out a warning call. I Remove dirt, stones, loose bark, nails, staples, and wire from the tree where cuts are to be made. g. Plan to stand on the up-hill side when cutting on a slope. Figure 17 . h.

FELLING LARGE TREES-6" Dia. Or More The notch method is used to cut large trees. A notch is cut on the side of the tree in the desired direction of fall. After a felling cut is made on the opposite side of the tree, the tree will tend to fall into the notch. NOTE: If the tree has large buttress roots, remove them before making the notch. Cut into the buttresses vertically, then horizontally. Figure 17 . a. Make the notch cut. Figure 19 . 1.) Cut the bottom of the notch first, through 1/3 of the diameter of the tree. 2.) Complete the notch by making the slant cut. 3.) Remove the notch of wood. b. Make felling cut on the opposite side of the notch about 2" higher than the bottom of the notch. c. Leave enough uncut wood between the felling cut and the notch to forma hinge. Figure 20 . A WARNING Stay on the uphill side of the terrain to avoid injury from the tree rolling or sliding downhill after it is felled. Figure 17 . NOTE: Before the felling cut is complete, use wedges to open the cut when necessaryto control the direction offall. Usewood or plasticwedges, but never steel or iron, to avoid kickback and chain damage.

Be alert to signs that the tree is ready to fall: 1.) Cracking sounds. 2.) Widening of the Felling Cut. 3.) Movement in the upper branches. e. As treestarts to fall,stop thesaw,putit down,and get away quickly on yourplanned retreat path. £ Be extremely cautious with partially fallen trees that may be poorly supported. When a tree doesn't fall completely, set the sawaside and pull down the tree with a cable winch, block and tackle, or tractor. To avoid injury, do not cut down a partially fallen tree with your saw. NOTE: The hinge helps to keep the tree from twisting and falling in the wrong direction. g. Use a wedge if there is any chance that the tree will not fail in the desired direction.

FELLING
LARGE
TREES
-6"
Dia.
Or
More
The
notch
method
is
used
to
cut
large
trees.
A
notch
is
cut
on
the
side
of
the
tree
in
the
desired
direction
of
fall.
After
a
felling
cut
is
made
on
the
opposite
side
of
the
tree,
the
tree
will
tend
to
fall
into
the
notch.
NOTE:
If
the
tree
has
large
buttress
roots,
remove
them
before
making
the
notch.
Cut
into
the
but-
tresses
vertically,
then
horizontally.

1.)
Cut
the
bottom
of
the
notch
first,
through
1/3
of
the
diameter
of
the
tree.
2.)
Complete
the
notch
by
making
the
slant
cut.
3.)
Remove
the
notch
of
wood.
b.
Make
felling
cut
on
the
opposite
side
of
the
notch
about
2"
higher
than
the
bottom
of
the
notch.
c. Leave
enough
uncut
wood
between
the
felling
cut
and
the
notch
to
forma
hinge.

NOTE:
Before
the

is
complete,
use

to
open

when
necessary
to

the
direction
of
fall.
Use

Be
alert
to
signs
that
the
tree
is
ready

fall:
1.)
Cracking

2.)
Widening

e.
As
tree
starts
to
fall,
stop
the
saw,
put
it
down,
and
get
away
quickly
on
your
planned
retreat
path.
£
Be
extremely
cautious
with
partially
fallen
trees
that
may
be
poorly
supported.
When
a
tree
doesn't
fall
completely,
set
the
saw
aside
and
pull
down
the
tree
with
a
cable
winch,
block
and
tackle,
or
tractor.
To
avoid
injury,
do
not
cut
down
a
partially
fallen
tree
with
your
saw.
NOTE:
The
hinge
helps
to
keep
the
tree
from
twist-
ing
and
falling
in
the
wrong
direction.
g.
Use
a
wedge
if
there
is
any
chance
that
the
tree
will
not
fail
in
the
desired
direction.
