Hinge holds tree on stump and helps control fall
Closing 0 notch
control the direction of fall. Use wood or plastic wedges, but never steel or iron, to avoid kickback and chain damage.
•Be alert to signs that the tree is ready to fall: cracking sounds, widening ofthefell- ing cut, or movement in the upper branches.
•Astreestartstofail,stopsaw, putitdown, and get away quickly on your planned re- treat path.
•Be extremely cautious with partially fallen trees that may be oorly supported. When a tree doesn’t Pall completely, set the saw aside and pull down the tree with a cable winch, block and tackle, ortractor. To avoid injury, do not cut down a partially fallen tree with your saw.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fall- en tree to the desired log length.
A WARNING: Do not stand on the log being cut. An potion can roll causin loss of footing an J control. Do not stand 8own- hill of the log being cut.
Important points
Cut only one log at a time.
Cut shattered wood very carefully; sharp pieces of wood could be flung toward op erator.
Use a sawhorse to cut small logs. Never
allow another person to hold the lo while cutting and never hold the log #ii’ your
leg or foot.
Do not cut in an area where logs, limbs, and roots aretangled. Drag the logsinto a clear area before cutting by pulling out ex- posed and cleared logs first
TYPES OF CUTTING USED
FOR BUCKING
,A 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 lastic or wood into the cut until the saw can lze removed easily. Restart the saw and carefully reenterthecut. 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.
Overcuttingbegins on the top side of the log with the saw a ainstthe log. When over- cutting use light 8ownward pressure.
OvmcuttlngUndercutting
Undercutting involves cutting on the un- derside of the log with top of saw againstthe log. When undercuttin use light upward pressure. Hold saw f?rmly and maintain control. The saw will tend to push back tr>- ward you.
A WARNING: Never turn saw upside down to undercut The saw cannot be con- trolled in this position.
