Pruning is the process of cutting limbs from a living tree.
1. Make the first cut approximately 6 inches (15 cm) from the
tree trunk. Cut upward, from the underside of the limb.
Use the top of the guide bar to make this cut. Cut a third of
the way through the diameter of the limb (Fig. 21).
2. Make the second cut 2 - 4 inches (5 - 10 cm) farther out on
the limb. Cut downward, from the top of the limb. Use the
bottom of the guide bar to make this cut. Cut completely
through the limb (Fig. 21).
3. Make the third cut as close to the tree trunk as possible.
Cut upward, from the underside of the limb stub. Use the
top of the guide bar to make this cut. Cut a third of the way
through the diameter of the limb (Fig. 21).
4. Make the fourth cut directly above the third cut.
Cut downward, from the top of the limb stub. Use the bottom
of the guide bar to make this cut. Cut completely through the
limb stub to meet the third cut (Fig. 21). This will remove the
limb stub.
