3. Felling Back Cut
Make the felling back cut at least 2 inches
(50.8 mm) higher than the horizontal
notching cut as illustrated in Figure 4. 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
chainsaw from the cut, stop the motor, put
the chain saw down, and then use the
retreat path planned. Be alert for overhead
limbs falling and watch your footing.
4. Limbing a Tree
Limbing is removing the branches from a
fallen tree. When limbing, leave larger
11
lower limbs to support the log off the
ground. Remove the small limbs in one cut
as illustrated in Figure 5. Branches under
tension should be cut from the bottom up
to avoid binding the chain saw.

5. 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 in Figure 6, it is cut from
the top (overbuck). When the log is
supported on one end, as illustrated in
Figure 7, cut 1/3 the diameter from the
underside (underbuck). Then make the
finished cut by over bucking to meet the first
cut. When the log is supported on both ends,
as illustrated in Figure 8, cut 1/3 of that
diameter from the top over buck. Then make
the finished cut by underbucking 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 in Figure
9. When "cutting through", to maintain
complete control release the cutting
