you and saw. Never make cuts with saw between your legs or
straddle the limb to be cut.
Bucking
Bucking is cutting a felled tree or log into lengths. How you should
cut depends on how the log is supported. Use a saw horse
(figure W) whenever possible.
Always start a cut with the chain running at full speed and the
ribbed bumper (5) in contact with the wood. To complete the cut use
a pivoting action of the ribbed bumper against the wood.
• (Figure S) When
supported along
its whole length
Make a cut from
the top (overbuck),
but avoid cutting
the earth as this
will dull your saw
quickly.
• (Figure T) When
supported at one
end
First, cut 1/3 the
diameter from the
underside
(underbuck). Then
make the finished
cut by
overbucking to
meet the first cut.
• (Figure Q) Felling
Back Cut - Make the
felling back cut at least
2 inches (51mm)
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.
• (Figure Q) 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.
Limbing (figure R)
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.
Branches under
tension should be cut from the bottom up to avoid binding the chain
saw. Trim limbs from opposite side keeping tree stem between
