TRIMMING A TREE (Pruning)
Trimming a tree is the process of cutting limbs from a living
tree. Make sure your footing is firm. Keep feet apart. Divide
your weight evenly on both feet. Follow directions below to
trim a tree.
1. Make first cut 15 centimeters (six inches) 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 (two to four inches) 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.

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 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.
