Cutting a Fallen Tree Bucking, Important Points

Hinge holds tree on stump and helps control fall

Opening of felling

Closing of notch

NOTE: Before felling cut is complete, use wedges to open the cut ff necessary to control the direction of fall. To avoid kickback and chain damage, use wood or plastic wedges, but never steel or iron wedges.

•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.

•As tree starts to fall, stop saw, put it down, and get away quickty on your planned re- treat path

•DO NOT cut down a partially failen tree with your saw. Be extremely caubeus with par- flally fallen trees that may be beody sup- ported. When a tree doesn't falI 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 size

A4_WARNING: Do not stand on thelog

being cut Any portion can roll causing loss of footing and control. Do not stand downhil_ of the log being cut.

IMPORTANT POINTS

•CUt onty one log at a time.

•Cut shattered wood very carefully; sharp

pieces of wood could be flung toward opera- toe

•Use a sawhorse to cut smaII Iogs. Never allow another person to hold the log while cutting and never hold the log with your leg or foot.

•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 pulliog out exposed and cleared logs first.

TYPES OF CUTTING USED FOR BUCKING

AqLWARNING:

If saw becomes

pinched or hung in a log, don't try to force it out. You can Iose control of the saw res ulting in injury and/or damage to the saw. Stop the saw, drive a wedge of plasfic or wood into the cut untiI the saw can be removed easiIy. Re- start the saw and carefully reenter the cut. To avoid kickback and chain damage, do not

use a metalwedge. 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

Overcutgng begins on the top side of the log with the bottom of the saw against the log

When overcutfiog use _ight downward pres- sure.

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 firmty and maintain control The saw will tend to push back toward you.

_WARNING: Neverturnsawogside

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.

First cut on compression side of Iog

Second cut

First cut on compression side of log

BUCKING WITHOUT A SUPPORT

•Overcut through 1/3 of the diameter of the log.

•Roll the log over and finish with a second overcut.

•Watch for logs with a compression side to prevent the saw from pinching. Bee il- Iustrabens for cutting logs with a compres- sion side.

BUCKING USING A LOG OR

SUPPORT STAND

•Remember your first cut is always on the compression side of the log.

(Refer to the illustraflons below for your first and second cut)

•Your first cut should extend 1/3 of the diameter of the log.

•Finish with your second cut.
