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 chain saw 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 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 ( ). 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 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.
