Release the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttle without a cutting load, unnec-
essary wear can occur to the chain,
bar, and engine.

To avoid losing control when cut is
complete, do not put pressure on saw
at end of cut.
S Stop the engine before setting the saw
down after cutting.
FELLING LARGE TREES
TREE FELLING TECHNIQUES
(6
inches in diameter or larger)
The notch method is used to fell large trees.
A notch is cut on the side of the tree in the de-
sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch.
NOTE: If the tree has large buttress roots,
remove them before making the notch. If
using saw to remove buttress roots, keep
saw chain from contacting ground to pre-
vent dulling of the chain.
WARNING: Check for broken or
dead branches which can fall while cutting
causing serious injury. Do not cut near build-
ings or electrical wires if you do not know the
direction of tree fall, norcut at night since you
will not be ale to see well, nor during bad
weather such as rain, snow, or strong winds,
etc. If the tree makes contact with any utility
line, the utility company should be notified
immediately.
S Carefully plan your sawing operation in ad-
vance.
NOTCH CUT AND FELLING THE
TREE
S Clear the workarea. You need a clear area
all around the tree so you can have secure
footing.
S Make notch cut by cutting the top of the
notch first. Cut through 1/3 of the diameter
of the tree. Next complete the notch bycut-
ting the bottom of the notch. See illus-
trated. Once the notch is cut remove the
notch of wood from the tree.
S The chain saw operator should keep on
the uphill side of the terrain as the tree is
likely to roll or slide downhill after it is felled
S Study the natural conditions that can
cause the tree to fall in a particular direc-
tion.
Final (felling) cut here. 2 inches
above center of notch.
First cut
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
sloping terrain. Use a plumb or level to de-
termine the direction of tree lean.
Notch
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted,
it can snap and fall toward the
operator.
Second cut
Hinge
Check for broken or dead branches which
can fall on you while cutting.
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 ob-
jects. Engine noise can drown out a warning
call.
S After removing the cutout of wood, make
the felling cut on the opposite side of the
notch. This is done by making a cut about
two inches higher than the center of the
notch. This will leave enough uncut wood
between the felling cut and the notch to
form a hinge. This hinge will help prevent
the tree from falling in the wrong direction.
Remove dirt, stones, loose bark, nails, sta-
ples, and wire from the tree where cuts areto
be made.
Plan a clear retreat path to the rear and diag-
onal to the line of fall.
