• Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them. LIMBING Always limb a tree after it is cut down. Only then can limbing be done safely and properly. Leave the larger limbs underneath the felled tree to support the tree as you work. Start at the base of the felled tree and work toward the top, cutting branches and limbs. Remove small limbs with one cut. Keep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting. Remove larger, supporting branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT. Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch the 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. 1. Make the first cut one-third of the way through the bottom of the limb. 2. Make the second cut all the way through the limb. 3. Make the third overcut leaving a 1 to 2 inch (2.5 to 5 cm) collar from the trunk of the tree. 2 1 3 MAINTENANCE WARNING!
