fELLING A TREE
Direction of fall
50mm
Notch
Notching Undercut – Make the notch 1/3 the diameter
of the tree, perpendicular to the direction of fall as
illustrated. Make the lower horizontal notching cut first.
This will help to avoid pinching of either the saw chain or
the guide bar when the second notch is being made.
Felling Back Cut – Make the felling back cut at least 2
inches (50.8 mm) higher than
the horizontal notching cut as illustrated. Keep the felling
back cut parallel to the horizontal notching cut. Make the
felling back cut so enough wood is left to act as a hinge.
The hinge wood keeps the tree from twisting and falling
in the wrong direction. Do not cut through the hinge. As
the felling cut gets close to the hinge the tree should
begin to fall. If there is any chance that the tree may not
fall in the desired direction or it may rock back and bind
the saw chain, stop cutting before the felling back cut is
complete and use wedges of wood, plastic or aluminum
to open the cut and drop the tree along the desired line
of fall.
When the tree begins to fall remove the chain saw from
the cut, stop the motor, put the chain saw down, then
use the retreat path planned. Be alert for overhead limbs
falling and watch your footing.
Limbing a Tree – Limbing is removing the branches from
a fallen tree. When limbing, leave larger lower limbs to
support the log off the ground. Remove the small limbs
in one cut as illustrated. Branches under tension should
be cut from the bottom up to avoid binding the chain
saw.
Felling Back Cut

Hinge
Bucking a Log – Bucking is cutting a log into lengths. It
is important to make sure your footing is firm and your
weight is evenly distributed on both feet. When possible,
the log should be raised and supported by the use of
limbs, logs or chocks. Follow the simple directions for
easy cutting.
When the log is supported along its entire length as
illustrated, it is cut from the top (over buck).
When the log is supported on one end, as illustrated,
cut 1/3 the diameter from the underside (under buck).
Then make the finished cut by over bucking to meet the
first cut. When the log is supported on both ends, as
illustrated, cut 1/3 of that diameter from the top over
buck. Then make the finished cut by under bucking the
lower 2/3 to meet the first cut. When bucking on a slope
always stand on the uphill side of the log, as illustrated.
When "cutting through", to maintain complete control
release the cutting pressure near the end of the cut
without relaxing your grip on the chain saw handles.
Don't let the chain contact the ground. After completing
the cut, wait for the saw chain to stop before you move
the chain saw. Always stop the motor before moving
from tree to tree.

Limb Cut
Keep work off ground support limbs until log is cut
2nd cut overbuck (2/3 diameter) to meet 1st
cut (to avoid pinching)
1st cut underbuck (1/3 diamter) to avoid splintering
