• 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:
• 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.

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.
