OPERATION
Do not cut trees near electrical wires or buildings (D).
Consider the direction in which the tree leans (E).
Check the tree for damaged or dead branches which
could fall and hit you during felling (F).
Periodically glance at the top of the tree during the
back-cut to assure the tree is going to fall in the
desired direction.
Keep all bystanders at a safe distance (G) (at least
twice the height of the tree).
Prepare a path of safe retreat (H).
If the tree starts to fall in the wrong direction, or if the
saw gets caught or hung up during the fall, leave the
saw and save yourself!
Consider the wind direction before felling a tree.
Do not fell trees near power lines or near buildings
which could be struck by falling limbs or the tree itself.
The chainsaw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled.
Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where felling cuts are to be
made.
WARNING
Do NOT fell trees near power lines or near
buildings which could be struck by falling limbs or
the tree itself.
PROPER PROCEDURE FOR TREE FELLING
(Fig. 28 - 31)
1. 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 (A).
2. 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 (B).
3. Cut a notch about 1/3 the diameter of the trunk
in the side of the tree (C). Make the notch cuts so
they intersect at right angles 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.
4. Make the back-cut (D) level and horizontal, and at a
minimum of 2 inches (5 cm) 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 inches (5 cm) or 1/10 the diameter of
the tree). This is called a "hinge" or "hingewood" (E).
It controls the fall of the tree and prevents slipping or
twisting or shoot-back 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
(F) into the cut so they do not touch the chain. Drive
wedges in, little by little, to help jack the tree over.
5. As tree starts to fall, stop the chainsaw and put it
down immediately. Retreat along the cleared path,
but watch the action in case something falls your way.
REMOVING BUTTRESS ROOTS (Fig. 32)
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 cut (A) into the
buttress first, followed by the vertical cut (B). Remove
the resulting loose section (C) from the work area. Follow
the correct tree felling procedure after you have removed
the large buttress roots. Refer to "Operation – Proper
Procedure for Tree Felling" earlier in this manual.
BUCKING (Fig. 33)
Bucking is the term used for cutting a fallen tree to the
desired log length.
Cut only one log at a time.
Support small logs on a sawing stand or another log
while bucking.
Keep a clear cutting area. Make sure that no objects
can contact the guide bar nose and chain during
cutting: this can cause kick-back (A).
During bucking operations, stand on the uphill side so
that the cut-off section of the log cannot roll over you.
Sometimes it is impossible to avoid pinching (with
just standard cutting techniques) or difficult to predict
which way a log will settle when 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 back-cut.
