OWNER’S MANUAL
4. As the felling cut gets close to the hinge,
the tree should begin to fall. If there is
any chance that the tree may not fall in
the desired direction or it may rock back
and bind the saw chain, stop cutting
before the felling back cut is complete
and use wedges of wood, plastic or
aluminum to open the cut and drop the
tree along the desired line of fall.
5. When the tree begins to fall remove the
chain saw from the cut, stop the motor,
put the chain saw down, then use the
retreat path planned. Be alert for overhead
limbs falling and watch our footing.

FELLING A TREE
WARNING: Felling a tree
should not be undertaken unless
the person has extensive experi-
ence or obtains professional as-
sistance.
CAUTION: When bucking and
felling operations are being per-
formed by two or more persons
at the same time, the felling op-
eration should be separated from
the bucking operation by a dis-
tance of at least twice the height
of the tree being felled. Trees
should not be felled in a manner
that would endanger any person,
strike any utility line or cause any
property damage. If the tree does
make contact with any utility line,
the utility company should be no-
tified immediately.
1. The chain saw operator should keep on
the uphill side of the terrain as the tree
is likely to roll or slide downhill after
it is felled.
2. CONSIDER the natural lean of the tree,
the location of larger branches and the
wind direction to judge which way the
tree will fall.
3. A RETREAT PATH should be planned
and cleared as necessary before cuts are
started. The retreat path should extend
back and diagonally to the rear of the
expected line of fall as illustrated in
Figure 11.
4.
CLEAR the work area around the tree
to be cut and on your retreat path.
5.
REMOVE dirt, stones, loose bark, nails,
staples, and wire from the tree where
felling cuts are to be made.

FELLING TECHNIQUES
1. Make the first lower notching cut 1/3
the diameter of the tree and
perpendicular to the line of fall. This
will help to avoid pinching of either the
saw chain or the guide bar when the
second notching cut is made (See
Figure 12).
2. Make the second upper notching cut at
an angle to meet the first notching cut
at 1/3 the diameter of the tree.
3. Make the felling back cut at least 2
inches higher than the horizontal
notching cut as illustrated in Figure 12.
Keep the felling back cut parallel to the
horizontal notching cut. Make the
felling back cut so enough wood is left
to act as a hinge. The hinge wood keeps
the tree from twisting and falling in the
wrong direction. DO NOT cut through
the hinge.
LIMBING
Limbing is removing the branches from a
fallen tree. When limbing, leave larger lower
limbs to support the log off the ground.
Remove the small limbs in one cut as illus-
trated in Figure 13. Branches under tension
should be cut from the bottom up to avoid
binding the chain saw.
Figure 13 - Limbing A Tree
Keep work off ground. Leave sup-
port limbs until log is cut.
Cutting a Limb
1. Make the first cut from the underside about
1/2 foot from the trunk and 1/3 through
the diameter of the limb (See Figure 10).
2. Make the second cut two to four inches
farther out on the limb from above until
the limb falls.
3. Make the third cut 1/3 the diameter of
the limb stub from underneath as close
to the trunk as possible.
4. Make the fourth cut from above as close
to the trunk as possible to meet the third
cut.
