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 the notch by cut-

ting the bottom of the notch. See illus tra-

tion. Once the notch is cut, remove the

notch of wood from the tree.

Final cut here. 2 inches above

center of notch.

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 enough uncut wood

betw e e n the fe llin g cut a n d the n o tc h to form

a hinge. This hinge will help prevent the tree

from fallin g in the wr on g dir e c tio n.

NOTE:

Before felling cut is complete, use

wedges to open the cut when necessary to

control the direction of fall. To avoid kickback

and 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:

crack ing 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 down the

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 size.

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 one log at a time.

S

Cut shattered wood very carefully; sharp

pieces of wood could be flung toward opera-

tor.

S

Use a sawhorse to cut small logs. Never

allow another person to hold the log while

cutting and never hold the log with your leg

or foot.

S

Do not cut in an area where logs, limbs,

and roots are tangled such as in a blown

down area. Drag the logs into a clear area

before cutting by pulling out exposed 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 of plastic or wood into the cut until the

saw can be r emoved easily . Restart the saw

and carefully reenter the cut. To avoid kickback

and chain damage, do not use a m etal wedge.

Do not attempt to r estart your saw when it is

pinched or hung in a log.

Use a wedge to remove pinched saw

Turn saw

OFF

and use a plastic or

wooden wedge to force cut open.

Overcutting

begins on the top side of the log

with the bottom of the saw against the log.

When overcutting use light downward pres-

sure.

Overcutting Undercutting

Undercutting

involves cutting on the under-

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.

Always make your first cut on the compres-

sion side of the log. The compression side of

the log is where the pressure of the log’s

weight is concentrated.
