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 10). 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. Felling Procedure A) 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 11). 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 11). 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 eight inches deep, start upper notch cut eight inches above it. Cut downward at 45° angle. The upper notch cut should meet end of lower notch cut (see Figure 11). 3. Remove tree trunk wedge created by notching cuts. B) Felling Cut 1. Make felling cut two inches higher than lower notch cut and on opposite side of tree (see Figure 11). Keep felling cut parallel to lower notch cut. 2. Cut towards notch. WARNING: Do not cut all the way through tree. Leave about two inches of tree diameter uncut directly behind felling notch (see Figure 11). This uncut portion acts as a hinge. The hinge helps keep tree from twisting and falling in wrong direction. 3. As felling cut nears hinge, tree should begin to fall. Note: If needed, drive wedges into felling cut to control direction of fall. If tree settles back and pinches chain, drive wedges into felling cut to remove saw. Only use wedges made of wood, plastic, or aluminum. 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 WARNING: Be alert for falling overhead limbs. Watch your footing while exiting area. 108539 18 OPERATING CHAIN SAW Continued LIMBING A TREE WARNING: When cutting limb that is under tension, use extreme caution. Be alert for wood springing back.

See Kickback, page 3, to avoid ri...
