Do not fell trees near electrical wires or buildings.

Leave this operation for professionals.
Cut only when visibility and light are adequate for you
Q
to see clearly.
BASIC OPERATING/CUTTING
PROCEDURES
Practice cutting a few small logs using the following
technique to get the "feel" of using the saw before you
begin a major sawing operation.
Take the proper stance in front of the wood with the
Q
saw idling.
Accelerate the engine to full throttle just before
Q
entering the cut by squeezing the throttle trigger.
Begin cutting with the saw against the log.
Q
Keep the engine at full throttle the entire time you are
Q
cutting.
Allow the chain to cut for you; exert only light
Q
downward pressure. Forcing the cut could result in
damage to the bar, chain, or engine.
Release the throttle trigger as soon as the cut is
Q
completed allowing the engine to idle. Running the
saw at full throttle without a cutting load can result in
unnecessary wear to the chain, bar, and engine.
Do not put pressure on the saw at the end of the
Q
cut as this may cause the saw to drop in an unsafe
manner.
OPERATION
FELLING TREES IN HAZARDOUS CONDITIONS
WARNING:
Do not fell trees during periods of high wind or
heavy rain. Wait until the hazardous weather
has ended. When felling a tree, it is important
that you heed the following warnings to prevent
possible serious injury.
Do not cut down trees having extreme lean or large
Q
trees with rotten limbs, loose bark, or hollow trunks.
Have these trees pushed or dragged down with
heavy equipment, then cut them up.
Do not cut trees near electrical wires or buildings.
Q
Check the tree for damaged or dead branches that
Q
could fall and hit you during felling.
Periodically glance at the top of the tree during the
Q
back cut to assure the tree is going to fall in the
desired direction.
If the tree starts to fall in the wrong direction, or if the
Q
saw gets caught or hung up during the fall, leave the
saw and save yourself!
PROPER PROCEDURE FOR TREE
FELLING
See Figures 23 - 26.
Pick your escape route (or routes in case the
Q
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

REMOVING BUTTRESS ROOTS
See Figure 27.
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 into the buttress
first, followed by the vertical cut. Remove the resulting
loose section from the work area. Follow the correct tree
felling procedure as stated in Proper procedure for tree
felling after you have removed the large buttress roots.
BUCKING
See Figure 28.
Bucking is the term used for cutting a fallen tree to the
desired log length.

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 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
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 into the cut so they do not touch the chain.
Drive wedges in, little by little, to help jack the tree
over.
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.
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.
Cut only one log at a time.
Support small logs on a saw horse or another log
while bucking.
