It is recommended that the first-time user should, as a
minimum practice, start cutting logs on a sawhorse or
cradle.
Before you start to fell a tree, make sure that:
•
The minimum distance between the areas of
bucking and felling performed by two or more
persons at the same time is two times the height
of the tree felled.
•
The operation does not:
•
Cause injury to personnel.
•
Hit utility lines. If the tree touches utility lines,
immediately tell the utility company.
•
Cause losses in property.
•
The user is not in the danger area (24), for example,
the downhill side of the area.
•
The escape paths (25) that extend back and
diagonally behind the felling direction (23) are clear.
The felling direction is controlled by:
•
The natural lean of the tree.
•
The location of larger branches.
•
The wind direction.
•
Ensure there is no dirt, stones, loose bark, nails, or
staples on the tree.

1. Make a lower-level notching cut (27). Make sure
that this cut is:
a) 1/3 width of the diameter of the tree.
b) Perpendicular to the felling direction.
The level notching cut helps prevent pinching of
the saw chain or the guide bar when you make the
second notch.
2. Make the felling cut (28) no less than 2 in. (50
mm) or higher than the level notching cut. Make
sure that this cut:
a) Is parallel to the level notching cut.
b) Keeps sufficient wood 2 in. (50 mm) or 1/10
the diameter of the tree to become a hinge (29)
which prevents the tree from twisting and felling
in the wrong direction.
When the felling cut (28) gets near the hinge (29),
the tree falls. Stop the felling cut if the tree:
2''(50mm)
28
2''(50mm)

•
Does not fall in the correct direction or
•
Moves backwards, causing the cutting bar and
chain to become stuck in the cut.
3. Use felling wedge to open the cut and let the tree
fall in the correct direction.
4. When the tree starts to fall:
a) Remove the chainsaw from the cut.
b) Stop the machine.
c) Put the machine down.
d) Move away from the tree via the escape path
(25). Always keep watching the tree to see
the direction of fall. Be careful with overhead
branches and your footing.

LIMB A TREE
30
Limbing is the removal of the branches from a fallen
tree.
1. Keep the larger lower branches to hold the log off
the ground (31).
2. Remove the small limbs (30) in one cut.
3. Limb the branches with tension from the bottom to
top.
4. Keep the larger lower branches as a support until
the log is limbed.
9.7
BUCK A LOG
To buck is to cut a log into lengths.
Do not let the chainsaw touch the ground.
It is important to make sure your footing is secure and
your weight is evenly distributed. If possible, lift the
log and hold it with branches, logs or chock. Obey the
instructions below:
When the log is held along the full length (32), cut it
from the top (33).
