II. General guidelines for felling trees.
Normally felling consists of 2 main cutting operations,
notching(C) and making the felling cut (D). Start
making the upper notch cut (C) on the side of the
tree facing the felling direction (E). Be sure you don't
make the lower cut too deep into the trunk. The notch
(e) should be deep enough to create a hinge (F) of
sufficient width and strength. The notch should be Fig
23 wide enough to direct the fall of the tree for as long
as possible.
Warning! Never walk in front of a tree that has been
notched. Make the felling cut (D) from the other side
of the tree and 3-5cm above the edge of the notch (C).
Warning! Don’t use the saw above shoulder-height,
because of difficult handling of the chainsaw which
can cause serious injury. Take care of a stable position
so you have good control on the chain saw.
Never saw completely through the trunk. Always
leave a hinge. The hinge guides the tree. If the trunk
is completely cut through, control over the felling
direction is lost. Insert a wedge or felling lever in the
cut well before the tree becomes unstable and starts
to move. This will prevent the guide bar from binding
in the felling cut if you have misjudged the falling
direction. Make sure no bystanders have entered the
range of the falling tree before you push it over.
Warning: As the felling cut (D) gets close to the hinge
(F), the tree should begin to fall. Remove saw from
cut, stop the engine, put the chainsaw down and
leave the area by the retreat path.
III. Felling cut.
Use wooden or plastic wedges (A) to prevent binding
the bar or chain (B) in the cut. Wedges also control
felling.
