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 acutting load, un-
necessary wear can occur to the
chain, bar, and engine.
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.

NOTCH CUT AND FELLING THE
TREE FELLING TECHNIQUES
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.
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.

ches above center of 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:
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 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.
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 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.

Plan a clear retreat path to the rear and diag-
onal to the line of fall.
