FELLING LARGE TREES

(15cmindiameterorlarger)

The notch method is used to fell large trees.

A notch is cut on the side of t he tree in thede-

sired direction of fall. After a felling cut is

made on the opposite side of tree, the tree

will tend to fall into the notch.

NOTCH CUT AND FELLING THE

TREE

S Make notch cut by cutting the top of the

notch first. Cut through

1/3 of the diameter

of the tree. Next complete thenotch bycut-

ting the bottom of the notch. See illustra-

tion. Once the notch is cut remove the

notch of wood from the tree.

S After removing the wood from the notch,

make the felling cut on the opposite side of

the notch. This is done by making a cut

about two inches higher than the center of

the notch. This will leave eno ugh uncut

wood between the felling cut and the notch

to form a hinge. Thishingewill helpprevent

the tree f rom falling in the wrong direction.

NOTE: Before felling cut is complete, use

wedges to open the cut when necessary to

control the direction of fall. To avoid kickback

or chain damage, use wood or plastic

wedges, but never steel or iron wedges.

S Be alert to signs that the tree is ready to fall:

cracking sounds, widening of the felling cut,

or movement in the upper branches.

S As tree starts to fall, stop saw, put it down,

and get away quickly on your planned re-

treat path.

S DO NOT cut down a partially fallen tree

with your saw . Be extremely cautious with

partially fallen trees that may be poorly

supported. When a tree doesn’t fall com-

pletely ,set the saw aside and pull downthe

tree with a cable winch, block and tackle,

or tractor.

CUTTING A FALLEN TREE

(BUCKING)

Bucking is the term used for cutting a fallen

tree to the desired log length.

WARNING: Do not stand on the log

being cut. Any portion can roll causing loss

of footing and control. Do not stand downhill

of the log being cut.

Important points

S Cut only o ne log at a time.

S Cut shattered wood very carefully; sharp

pieces ofwoodcould beflung toward oper-

ator.

S Use a sawhorse to cut small logs. Never

allow another person to hold the log while

cutting and never holdthe log with your leg

or foot.

S Do not cut in an area where logs, limbs,

and roots are tangled. Drag the logs into a

clear area before cutting by pulling out ex-

posed and cleared logs first.

TYPES OF CUTTING USED FOR

BUCKING

WARNING: If saw becomes pinched

or hung in a log, don’t try to force it out. You

can lose control of the saw resulting in injury

and/or damage to the saw. Stop the saw,

drive a wedge o f plastic or wood into the cut

until thesaw can beremoved easily . Restart

the saw and carefully reenter t he cut. Do not

attempt to restart your saw when it ispinched

or hung in a log.

Turn saw OFF and use a plastic or

wooden wedge to force cut open.

Overcutting begins on thet op side of t helog

with the saw against the log. When overcut-

ting use light downward pressure.

Overcutting

Undercutting

Undercutting involves cutting on theunder-

side of the log with top of saw against the log.

When undercutting use light upward pres-

sure. Hold saw firmly and maintain control.

The saw will tend to push back toward you.

WARNING: Never turn saw upside

down to undercut. The saw cannot be con-

trolled in this position.
