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 gets close to the hinge, the tree
should begin to fall. If there is any chance that the
tree may not fall in 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 aluminium (Z) 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 Chainsaw
down, then use the retreat path planned (
alert for overhead limbs falling and watch your
footing. (See Figure 1)

4. 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 in Figure 2. Branches under
tension should be cut from the bottom up to avoid
binding the Chainsaw.

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 3, it is cut from the top
(overbuck), avoid contacting ground as this will
greatly reduce the chain sharpness.

When the log is supported on one end, as
illustrated in Figure 4, cut 1/3 the diameter from
the underside (underbuck) (1). Then make the
finished cut by overbucking (2) to meet the first
cut.

When the log is supported on both ends, as
illustrated in Figure 5, cut 1/3 the diameter from the
top (overbuck) (1). Then make the finished cut by
underbucking (2) 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 6.
When "cutting through", to maintain complete
control release the cutting pressure near the end of
the cut without relaxing your grip on the Chainsaw
