Opening

Closing of

notch

Hinge holds tree on stump and helps

control fall

NOTE:

Before felling cut is complete, use

wedges to open the cut if 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: cracking sounds, widening of the fell-

ing 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 removed easily. Re-

start the saw and carefully reenter the cut. To

avoid kickback and chain damage, do not

use a metal wedge. Do not attempt to restart

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.

Second cut

First cut on compression side of log

First cut on compression side of log

Second cut

BUCKING WITHOUT A SUPPORT

S

Overcut through

1/3

of the diameter of the

log.

S

Roll the log over and finish with a second

overcut.

S

Watch for logs with a compression side to

prevent the saw from pinching. See il-

lustrations for cutting logs with a compres-

sion side.

BUCKING USING A LOG OR

SUPPORT STAND

S

Remember your first cut is always on the

compression side of the log.

(Refer to the illustrations below for your

first and second cut)

S

Your first cut should extend

1/3

of the

diameter of the log.

S

Finish with your second cut.
