McCulloch 952801946 Cutting a Fallen Tree, Important points, Types of Cutting Used for Bucking

Page 11

SAs tree starts to fall, stop saw, put it down, and get away quickly on your planned re-

treat path.

SDO 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

SCut only one log at a time.

SCut shattered wood very carefully; sharp pieces of wood could be flung toward oper-

ator.

SUse 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.

SDo 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.

BUCKING WITHOUT A

SUPPORT

SOvercut through 1/3 of the diameter of the log.

SRoll the log over and finish with a second overcut.

SGive 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

SRemember 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.

SFinish with your second cut.
