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 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.

). Be alert for overhead limbs falling and watch your footing.
