Safety Information (Continued)
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 3.
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 4. Make the
lower horizontal notching cut first. This will help to avoid pinching of either the saw chain or the guide bar when the
second notch is being made.
3. Felling Back Cut
Make the felling back cut at least 2 inches (50.8 mm) higher thanthe horizontal notching cut as illustrated in Figure 4.
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 cut gets close to the hinge the tree should begin to fall. If there is any chance that the tree may
not fall in the 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 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.
