Cut 1/3 through diameter of limb (see Figure 11). 2. Move five to ten centimeters farther out on limb. Make second cut from above limb. Continue cut until you cut limb off. 3. Make third cut as close to tree trunk as possible on underside of limb stub. Use top of guide bar to make this cut. Cut 1/3 through diameter of stub. 4. Make fourth cut directly above third cut. Cut down to meet third cut. This will remove limb stub.

Do not endanger any person, strike utility lines, or cause property damage. If tree strikes utility lines, contact utility company at once. WARNING • Avoid kickback. Kickback can result in severe injury or death. See Kickback,pages 3 and 4, to avoid risk of kickback. • Do not fell a tree without ample skill or expert help. • Keep children, animals, and bystanders away from area when felling a tree. • If two or more persons per- form bucking and felling op- erations at the same time, pro- vide ample distance between operations.

Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Follow directions below to fell a tree. Before Felling a Tree 1. Before felling, inspect tree. Make sure there are no dead limbs or branches that may fall on you. Study natural lean of tree, location of larger branches, and wind direction. This will help you judge which way tree will fall. 2. Clear work area around tree. 3. Plan and clear a retreat path before felling. Make retreat path opposite to planned direction of fall of tree and at 45° angle (see Figure 12). 4. Remove dirt, stones, loose bark, nails, staples, and wire from tree where you will make felling cuts. 5. Stay on uphill side when felling tree. Tree could roll or slide downhill after falling. Figure 12 - Retreat Path From Tree Retreat Path Direction of Fall 45° Retreat Path Tree 10 102891 OWNER’S MANUAL OPERATING CHAIN SAW Continued FELLING PROCEDURE Felling Notch A properly placed felling notch will determine direction tree will fall. Place felling notch on side of tree in direction you want tree to fall (see Figure 13). Follow directions below to create a felling notch. 1. Make lower notch cut as close to ground as possible. Hold saw so guide bar is horizontal. Cut 1/3 the diameter of tree trunk (see Figure 13). Note:Always make this horizontal lower notch cut first. If you make this cut second, tree can pinch chain or guide bar. 2. Start upper notch cut the same distance above first cut as first cut is deep. Example:If lower notch cut is 20 centimeters deep, start upper notch cut 20 centimeters above it. Cut downward at 45° angle. The upper notch cut should meet end of lower notch cut (see Figure 13). 3. Remove tree trunk wedge created by notching cuts. Felling Cut 1. Make felling cut five centimeters higher than lower notch cut and on opposite side of tree (see Figure 13). Keep felling cut parallel to lower notch cut. 2. Cut towards notch. Never use wedge made of steel. This could cause kickback and damage to chain. 4. When tree begins to fall, quickly •remove saw from felling cut •release trigger to turn saw off • put saw down •exit area using retreat path Direction of Fall WARNING: Be alert for falling overhead limbs. Watch your foot- ing while exiting area.
