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 par-

tially fallen trees that may be poorly sup-

ported. When a tree doesn’t fall completely,

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 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 one log at a time.

S

Cut shattered wood very carefully; sharp

pieces of wood could be flung toward oper-

ator.

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. 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 of plastic or wood into the cut

until the saw can be removed easily. Restart

the saw and carefully reenter the cut. Do not

attempt to restart your saw when it is pinched

or hung in a log.

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 saw against the log. When overcut-

ting use light downward pressure.

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.

First cut on pressure side of log

Second cut

First cut on pressure 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

Give special attention to logs under strain

to prevent the saw from pinching. Make

the first cut on the pressure side to relieve

the stress on the log.

BUCKING USING A LOG OR SUP-

PORT STAND

S

Remember your first cut is always on the

pressure side of the log.

S

Your first cut should extend

1/3

of the

diameter of the log.

S

Finish with your second cut.
