FELLING BACK A CUT
LIMBING A TREE
BUCKING A LOG
Make the felling back cut at least 50 mm
higher than the horizontal notching cut (Figure
9). 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 gets close to the hinge, the tree
should begin to fall. If there is any chance
that the tree may not fall in 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
aluminium 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.Bealertforoverheadlimbsfalling
and watch your footing.
Limbing is 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 (Figure 10).

the bottom up to avoid binding the chain saw.
When the log is supported on one end,cut 1/3

When the log is supported on both ends,
cut 1/3 the diameter from the top (overbuck)
(Figure13).Thenmakethenishedcut

When bucking on a slope always stand on the
uphill side of the log (Figure 14).

and your weight is evenly distributed on both
feet. When possible, the log should be raised
and supported by the use of limbs, logs or
chocks. Follow the simple directions for easy
cutting. When the log is supported along its
entire length, it is cut from the top (overbuck)
(Figure 11).
To maintain complete control when cutting
through a log, release the cutting pressure
near the end of the cut without relaxing your
grip on the chain saw handles. Don’t let the
chain contact the ground. After completing the
cut, wait for the saw chain to stop before you
move the chain saw. Always stop the motor
before moving from tree to tree.
