Allow the chain to cut for you. Exert
only light downward pressure. If you
force the cut, damage to the bar,
chain, or engine can result.
FELLING LARGE TREES
(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.
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.
NOTE: If the tree has large buttress roots,
remove them before making the notch. If us-
ing saw to remove buttress roots, keep saw
chain from contacting ground to prevent dull-
ing of the chain.
S
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

TREE FELLING TECHNIQUES
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 illustra-
tion. Once the notch is cut remove the
notch of wood from the tree.
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.
Final (felling) cut here. 2 in-
ches above center of notch.
First cut
Notch
S Carefully plan your sawing operation in ad-
vance.
S Clear the workarea. You need a clear area
all around the tree so you can have secure
footing.
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 direction.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
Hinge
Second cut
S After removing the wood from the notch,
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 pre-
vent the tree from falling in the wrong direc-
tion.
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.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted,

Opening
of felling
cut
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. En-
gine noise can drown out a warning call.
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.

NOTE: Before felling cut is complete, use
wedges to open the cut if necessary to
control the direction of fall. To avoid kickback
and chain damage, use wood or plastic
wedges, but never steel or iron wedges.
