S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair parts as
necessary.
Plan a clear retreat path
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
and increase the possibility of kickback.

Practice cutting a few small logs us-
ing the following techniques to get
the “feel” of using your saw before
you begin a major sawing operation.
Squeeze the throttle trigger and al-
low the engine to reach full speed
before cutting.

FELLING LARGE TREES
(6 inches in diameter or larger)
Begin cutting with the saw frame
against the log.
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.

Keep the engine at full speed the en-
tire time you are cutting.
Allow the chain to cut for you. Exert
only light downward pressure.
Release the throttle trigger as soon
as the cut is completed, allowing the
engine to idle. If you run the saw at
full throttle without a cutting load, un-
necessary wear can occur.
NOTE
:
If the tree has large buttress roots,
remove them before making the notch.
NOTCH CUT AND FELLING THE
TREE
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.
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
down.
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.

TREE FELLING TECHNIQUES
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, at night since you will not
be able to see well, or during bad weather
such as rain, snow, or strong winds, etc.
S Carefully plan your sawing operation in ad-
vance.
above center of notch.
First cut
Notch
S Clear the workarea. You need a clear area
all around the tree so you can have secure
footing.
S Study the natural conditions that can
cause the tree to fall in a particular direc-
tion.
Natural conditions that can cause a tree to
fall in a particular direction include:
Second cut
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.

control fall
Opening

cut
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.
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.
Closing of

NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to
control the direction of fall. To avoid kickback
