GENERAL GUIDELINES
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 (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:
Make the felling cut (D) from the other side of
the tree and 1.5" - 2.0" (3-5cm) above the edge
of the notch (C) (Figure 18).
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 mis-
judged the falling direction. Make sure no bystanders have
entered the range of the falling tree before you push it over.
WARNING:
bystanders, animals or obstacles.

FELLING CUT:
1. Use wooden or plastic wedges (G) to prevent binding
the bar or chain (H) in the cut. Wedges also control
felling (Figure 19).
2. When diameter of wood being cut is greater than the bar
length, make 2 cuts as shown (Figure 20).
WARNING:
When tree begins to fall, remove saw from cut,
stop engine, put chain saw down, and leave
area along retreat path (Figure17).
