1st Cut 2nd Cut LIMBING AND PRUNING WARNING: Be alert for and guard against kickback. 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 position which can cause you to lose your balance or control of the saw. IMPORTANT POINTS S Work slowly, keeping both hands firmly gripped on saw. Maintain secure footing and balance. S Watch out for springpoles. Use extreme caution when cutting small size limbs. Slender material may catch saw chain and be whipped toward you or pull you off balance. 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 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 as much as possible. Cut from the side of the tree opposite the branch your are cutting. S Remove larger, supporting branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT. S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch saw. PRUNING WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job. S Make your fist cut 1/3 of the way through the bottom of the limb. S Next make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 1 to 2 inch collar from the trunk of the tree.
