2. Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular
to the direction of falls 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 50 mm 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 aluminium (Z) 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 (

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