OPERATION
Begin the cut on the side to
which the tree is to fall. Cut a
notch about 1/3 of the way into
the tree. The position of this
notch is important since the tree
will try to fall "into" the notch. The
felling cut is made on the side
opposite the notch and at a level
about 5 cm (2 in.) above the
bottom of the notch. Do not try to
cut through to the notch with the
felling cut. The remaining wood
between the notch cut and felling
cut about 5 cm (2 in.) will act as a hinge when the tree falls, guiding it in the
desired direction. When the tree starts to fall, kill the engine, place the saw
on the ground and make your retreat quickly.
To fell big trees with a diameter
exceeding twice the bar length, start
the notching cuts from one side and
draw the saw through to the other
side of the notch. Start the back cut
on one side of the tree, pivoting the
saw through to form the desired hinge
on that side. Then remove the saw for
the second cut. Insert the saw in the
first cut, very carefully so as not to
cause kickback. The final cut is made
by drawing the saw forward in the cut to reach the hinge.
Limbing
Limbing a fallen tree is much the
same as bucking. Never stand on the
tree that you are limbing. When
limbing, caution is the word. Be
careful of the tip touching other limbs.
Always use both hands.
