DeWalt DCCS620 Instruction Manual page 43

• 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
2" (51 mm)
NOTCH
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.

WARNING: Recommend that first time users should
practice cutting on a saw horse.
FELLING BACK CUT
2" (51 mm)
HINGE
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.
• Always start a cut with the chain running at full speed.
• Place the bottom spike
area of the initial cut.
• Turn the chain saw on then rotate the chain and bar
down into the tree, using the spike as a hinge.
• Once the chain saw gets to a 45 degree angle, level
the chain saw again and repeat steps until you cut
fully through.
• 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.

• When supported at one end
First, cut 1/3 the diameter from the underside
(underbuck). Then make the finishing cut by overbucking
to meet the first cut.

• When supported at both ends.
First, cut 1/3 down from the top overbuck. Then make
the finished cut by underbucking the lower 2/3 to meet
the first cut.
