1.Make ﬁrst cut 15 centimeters from tree trunk on underside of limb. Use top of guide bar to make this cut. 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.

CAUTION: Seek professional help if facing conditions beyond your ability.

Felling is the process of cutting down a tree. 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 fell- ing. 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.
