SAVE THESE INSTRUCTIONS
Instructions concerning the proper techniques for basic
felling, limbing, and cross-cutting:
1. Felling a tree
When bucking and felling operations are being performed
by two or more persons at the same time, the felling
operations should be separated from the bucking
operation by a distance of at least twice the height of the
tree being felled. Trees should not be felled in a manner
that would endanger any person, strike any utility line
or cause any property damage. If the tree does make
contact with any utility line, the company should be
notified immediately.
The chainsaw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled.
An escape path should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of the
expected line of fall as illustrated in Figure 1.
Before felling is started, consider the natural lean of
the tree, the location of larger branches and the wind
direction to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples and wire
from the tree.
2. Notching undercut
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of fall as illustrated in
Figure 1. Make the lower horizontal notching cut (W)
first. This will help to avoid pinching either the saw chain
or the guide bar when the second notch (X) is being
made.
3. Felling back cut
Make the felling back cut (Y) at least
2” (5 cm) higher than the horizontal notching cut as
illustrated in Figure 1. 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 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 aluminum
(Z) to open the cut and drop the tree along the desired
line of fall (
3
)
.
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 (
2
). Be 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.
