FELLING THE TREE

A falling tree can seriously damage anything it may 
hit - a car, a house, a fence, a power-line, or  
another tree.  
There are ways to make a tree fall where you want 
it, so first decide where that is!  
Before cutting, clear the area around the tree.  
You will need good footing while working and you 
should be able to work the saw without hitting any 
obstacles.  
Next, select a path of retreat.  
When the tree begins to fall you should retreat 
away from the direction of fall at a 45-degree angle 
and at least 3 m (10 feet) from the trunk to avoid 
the trunk kicking back over the stump. 

Begin the cut on the side to which the tree is to fall. 
Cut a notch about 1/3 of the way into the tree. The 
position of this notch is important since the tree will 
try to fall “into” the notch.  
The felling cut is made on the side opposite the 
notch and at a level about 5 cm (2 in.) above the 
bottom of the notch.  
Do not try to cut through to the notch with the  
felling cut.  
The remaining wood between the notch cut and 
felling cut about 5 cm (2 in.) will act as a hinge 
when the tree falls, guiding it in the desired  
direction.  
When the tree starts to fall, kill the engine, place 
the saw on the ground and make your retreat 
quickly. 

To fell big trees with a diameter exceeding twice 
the bar length, start the notching cuts from one 
side and draw the saw through to the other side of 
the notch.  
Start the back cut on one side of the tree, pivoting 
the saw through to form the desired hinge on that 
side.  
Then remove the saw for the second cut. Insert 
the saw in the first cut, very carefully so as not to 
cause kickback.  
The final cut is made by drawing the saw forward 
in the cut to reach the hinge.
