Hinge holds tree on stump and helps control fall Opening of felling Closing of notch cut 11 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. 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 retreat path. S 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 S Cut only one log at a time. S Cut shattered wood very carefully; sharp pieces of wood could be flung toward operator. 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 such as in a blown down area. Drag the logs into a clear area before cutting by pulling out exposed 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. 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. Use a wedge to remove pinched saw 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 bottom of the saw against the log. When overcutting use light downward pressure. OvercuttingUndercutting 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. WARNING: Never turn saw upside down to undercut. The saw cannot be controlled in this position. Always make your first cut on the compression 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 log Second cut Second cut First cut on compression side of log 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 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 S Remember your first cut is always on the compression side of the log. (Refer to the illustrations below for your first and second cut) S Your first cut should extend 1/3 of the diameter of the log. S Finish with your second cut.

Do not allow the moving chain to contact any other branches or objects at the nose of the guide bar when limbing or pruning. Allowing such contact can result in serious injury. WARNING: Never climb into a tree to limb or prune. Do not stand on ladders, platforms, a log, or in any positionwhich can cause you to lose your balance or control of the saw. IMPORTANT POINTS S Work slowly, keeping both hands firmly gripped on the saw. Maintain secure footing and balance. S Watch out for springpoles. Springpoles are small size limbs which can catch the saw chain and whip toward you or pull you off balance. Use extreme caution when cutting small size limbs or slender material. S Be alert for springback. Watch out for branches that are bent or under pressure. Avoid being struck by the branch or the saw when the tension in the wood fibers is released. S Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them. LIMBING S Always limb a tree after it is cut down. Only then can limbing be done safely and properly. S Leave the larger limbs underneath the felled tree to support the tree as you work. S Start at the base of the felled tree and work toward the top, cutting branches and limbs. Remove small limbs with one cut. S Keep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting. S Remove larger, supporting branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT. S ...
