OPERATION PROPER PROCEDURE FOR TREE FELLING See Figures 21 - 24. n Pick your escape route (or routes in case the intended route is blocked). Clear the immediate area around the tree and make sure there are no obstructions in your planned path of retreat. Clear the path of safe retreat approximately 135° from the planned line of fall. n Consider the force and direction of the wind, the lean and balance of the tree, and the location of large limbs. These things influence the direction in which the tree will fall. Do not try to fell a tree along a line different from its natural line of fall. n Cut a notch about 1/3 the diameter of the trunk in the side of the tree. Make the notch cuts so they intersect at a right angle to the line of fall. This notch should be cleaned out to leave a straight line. To keep the weight of the wood off the saw, always make the lower cut of the notch before the upper cut. n Make the backcut level and horizontal, and at a minimum of 2 in. above the horizontal cut of the notch. NOTE: Never cut through to the notch. Always leave a band of wood between the notch and back cut (approximately 2 in. or 1/10 the diameter of the tree). This is called "hinge" or "hingewood." It controls the fall of the tree and prevents slipping or twisting or shootback of the tree off the stump. n On large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so they do not touch the chain. Drive wedges in, little by little, to help jack the tree over. NOTE: When bucking or felling with a wedge, it may be necessary to remove the SAFE-T-TIP® anti-kickback device to allow the bar to be drawn through the cut. After you complete the cut, reinstall the tip immediately. n As tree starts to fall, stop the chain saw and put it down immediately. Retreat along the cleared path, but watch the action in case something falls your way.

OPERATION
PROPER PROCEDURE FOR TREE
FELLING
See Figures 21 - 24.
Pick your escape route (or routes in case the
intended route is blocked). Clear the immediate
area around the tree and make sure there are
no obstructions in your planned path of retreat.
Clear the path of safe retreat approximately 135°
from the planned line of fall.
Consider the force and direction of the wind, the
lean and balance of the tree, and the location of
large limbs. These things influence the direction
in which the tree will fall. Do not try to fell a tree
along a line different from its natural line of fall.
Cut a notch about 1/3 the diameter of the trunk
in the side of the tree. Make the notch cuts so
they intersect at a right angle to the line of fall.
This notch should be cleaned out to leave a
straight line. To keep the weight of the wood
off the saw, always make the lower cut of the
notch before the upper cut.
Make the backcut level and horizontal, and at
a minimum of 2 in. above the horizontal cut of
the notch.
NOTE:
Never cut through to the notch. Always
leave a band of wood between the notch
and back cut (approximately 2 in. or 1/10 the
diameter of the tree). This is called “hinge” or
“hingewood.” It controls the fall of the tree and
prevents slipping or twisting or shootback of
the tree off the stump.
On large diameter trees, stop the back cut
before it is deep enough for the tree to either
fall or settle back on the stump. Then insert soft
wooden or plastic wedges into the cut so they
do not touch the chain. Drive wedges in, little
by little, to help jack the tree over.
NOTE:
When bucking or felling with a wedge, it
may be necessary to remove the SAFE-T-TIP
®
anti-kickback device to allow the bar to be
drawn through the cut. After you complete the
cut, reinstall the tip immediately.
As tree starts to fall, stop the chain saw and put
it down immediately. Retreat along the cleared
path, but watch the action in case something
falls your way.
HINGE
BACK CUT

WARNING:
Never cut through to the notch when making a
back cut. The hinge controls the fall of the tree,
this is the section of wood between the notch
and backcut.
REMOVING BUTTRESS ROOTS
See Figure 25.
A buttress root is a large root extending from the
trunk of the tree above the ground. Remove large
buttress roots prior to felling. Make the horizontal
