Common Cutting Techniques
Felling
The process of cutting down a tree. Be sure battery is fully
charged before felling a tree so you can finish on a single
charge. 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.

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.
• 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 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 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.

DIRECTION OF FALL
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 chain saw. 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.
DIRECTION
OF
FALL
Bucking

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.

WARNING: Recommend that first time users should
practice cutting on a saw horse.
Always start a cut with the chain running at full speed.
Place the bottom spike 22

Turn the chain saw on then rotate the chain and bar
down into the tree, using the spike as a hinge.
