S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull achain
and thus increase the possibility of kick-
back.
S Practice cutting a few small logs using the
following techniques to get the “feel” of us-
ing your saw before you begin a major
sawing operation.
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.
Remove dirt, stones, loose bark, nails, sta-
ples, and wire from the tree where cuts areto
be made.
S
Squeeze the throttle trigger and allow
the engine to reach full speed before
cutting.
Plan a clear retreat path to the rear and diag-
onal to the line of fall.

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. If you
force the cut, damage to the bar,
chain, or engine can result.

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. It is recommended
that the engine not be operated for
longer than 30 seconds at full
throttle.
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.
S
To avoid losing control when cut is
complete, do not put pressure on saw
at end of cut.
NOTE: If the tree has large buttress roots,
remove them before making the notch.
S Stop the engine before setting the saw
down after cutting.
NOTCH CUT AND FELLING THE
TREE
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.
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.
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.
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 lean of the tree. The lean of a tree
might not be apparent due to uneven or
