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.
Don’t cut with the saw overhead or aligned vertically with your
body. If the saw should kickback, you may not have enough
control to prevent possible injury.
