Common Cutting Techniques
Felling
The process of cutting down a tree. Do not fell trees in high
wind conditions.

WARNING: Felling can result in injury. It should only be
performed by a trained person.
• A retreat path should be planned and cleared as necessary
before cuts are started. The retreat path should extend back and
diagonally to the rear of the expected line of fall as shown below.

RETREAT
• 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. Have wedges (wood, plastic or
aluminum) and a heavy mallet handy. Remove dirt, stones, loose
bark, nails, staples, and wire from the tree where the felling cuts
are to be made.
• notching Undercut - Make the notch 1/3 of the diameter
of the tree, perpendicular to the direction of the fall. 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 cut is being made as shown below.
• Felling Back cut - Make the felling back cut at least 2"
(51 mm) higher than the horizontal notching cut. 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 shown below.
• 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 cut is complete and use wedges
to open the cut and drop the tree along the desired line of fall.
When the tree begins to fall remove the chainsaw from the cut,
stop the motor, put the chainsaw down, then use the retreat
path planned. Be alert for overhead limbs falling and watch
your footing.

Limbing
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. Branches under tension should be cut from
the bottom of the branch towards the top to avoid binding the
chainsaw as shown below. Trim limbs from opposite side keeping
tree stem between you and saw. Never make cuts with saw
between your legs or straddle the limb to be cut.

WARNING: Recommend that first-time users should practice
cutting on a saw horse.
Cutting a felled tree or log into lengths. How you should
cut depends on how the log is supported. Use a saw horse
whenever possible as shown below.
1. Always start a cut with the saw chain running at full speed.
2. Place the bottom spike

of the initial cut as shown below.
3. Turn the chainsaw on then rotate the saw chain and bar
down into the tree, using the spike as a hinge.
4. Once the chainsaw gets to a 45 ° angle, level the chainsaw
again and repeat steps until you cut fully through.
5. When the tree is supported along its entire length, make a
cut from the top (overbuck), but avoid cutting the earth as this
will dull your saw quickly.
