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. • Be alert to signs that the tree is ready to fall: cracking sounds, widening of the felling cut, or movement in the upper branches. • As tree starts to fall, stop saw, put it down, and get away quickly on your planned retreat path. • 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 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. ,_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 • Cut only one log at a time. • Cut shattered wood very carefully; sharp pieces of wood could be flung toward operator. • 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. • 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. Use a wedge to remove pinched saw Turn saw OFF and use a plastic or wooden wedge to force cut open. OvercutUng begins on the top side of the log with the bottom of the saw against the log. When overcutting use light downward pressure. _L_ Overcutting _/ Undercutting ""-',b Undercutting involves cutting on the underside of the log with top of saw against the log. When undercutting use light upward pressure. Hold saw firmly and maintain control. The saw will tend to push back toward you. _ILWARNING: Nevertum saw up- side down to undercut. The saw can- not be controlled in this position. Always make your first cut on the compression side of the log. The compres- sion side of the log is where the pres- sure of the log's weight is concentrated. First cut on compression side of log Second cut Second cut TYPES OF CUTTING USED FOR BUCKING _I, 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. 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. First cut on compression side of log BUCKING WITHOUT A SUPPORT • Overcut through 1/3of 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. See illustrations for cutting logs with a compression side. BUCKING USING A LOG OR SUPPORT STAND • Remember your first cut is always on the compression side of the log. 12
