1. Make a lower level notching cut (27). Make sure
that this cut is
a) 1/3 wide of the diameter of the tree.
b) Perpendicular to the felling direction.
CAUTION
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 no less than 2 in. (50 mm)
and higher than the level notching cut. Make
sure that this cut
a) Is parallel to the level notching cut.
b) Keeps sufficient wood 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
• 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
it's direction of fall, be careful with overhead
branches and your footing.

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.
9.8 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).
When the log is held on one end (34):
1. Cut the first time 1/3 of the diameter from the bottom
(35).
2. Cut the second time from the top (36) to complete
the bucking.
When the log is held on two ends (37):
1. Cut the first time 1/3 of the diameter from the top
(36).
