from its natural line of fall.
3. 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.
4. Make the back cut 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 a “hinge” or “hinge wood.” It controls
the fall of the tree and prevents slipping or twisting or
shooting back of the tree off the stump.
5. 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.
6. As the 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.

n Work slowly, keeping both hands on the saw with a
firm grip. Maintain secure footing and balance.
n Keep the tree between you and the chain while limbing.
n Do not cut from a ladder. This is extremely dangerous.
Leave this operation for professionals.
n Do not cut above chest height. A saw held higher than
chest height is difficult to control against kickback.
