S 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, unneces-
sary wear can occur to the chain, bar
and engine.
S To avoid losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
S Stop the engine before setting the saw down.
TREE FELLING TECHNIQUES
WARNING:
Check for broken or dead
branches which can fall while cutting causing
serious injury. Do not cut near buildings 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. If tree makes con-
tact with any utility line, the utility company
should be notified immediately.
S Carefully plan your sawing operation in ad-
vance.
S Clear the work area. 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.
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
tree lengths
2-1/2
from the nearest person or other objects. En-
gine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where cuts are to be
made.
Plan a clear retreat path to the rear and diago-
nal to the line of fall.

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.
