General guidelines for felling trees (Fig. 22)
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 (C) should be deep enough to create a hinge
(F) of sufficient width and strength. The notch should be 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
1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C).
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
guidebar 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:
Before making the final cut, always recheck the area
for bystanders, animals or obstacles.
Felling cut
1
Use wooden or plastic wedges (A) to prevent
binding the bar or chain (B) in the cut. Wedges also
control felling (Fig. 23).
2
When diameter of wood being cut is greater than
the bar length, make 2 cuts as shown (Fig. 24).
Warning:
As the felling cut gets close to the hinge, the tree
should begin to fall. When tree begins to fall, remove saw
from cut, stop engine, put chain saw down, and leave area
along retreat path (Fig. 21).
Limbing
Limbing a tree is the process of removing the branches from a
fallen tree. Do not remove supporting limbs (A) until after the
log is bucked (cut) into lengths (Fig. 25). Branches under
tension should be cut from the bottom up to avoid binding the
chain saw.
Warning:
Never cut tree limbs while standing on tree trunk.
