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.

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.
37
When the log is held on two ends (37):
1. Cut the first time 1/3 of the diameter from the top (36).
