PRUNING AND LIMBING
Pruning is removingbranches from a standing tree. Limbing is removing branches from a felled tree.
LIMBING (Fig. 17)

•Leave the larger limbs underneath the felled tree to supportthe tree as you work.
PRUNING PROCEDURE
•Cut 1 - Undercut 1/3 of the way through the limb near the trunk of the tree.
•Cut 2 - Finish with an overcut farther out from the trunk until the limb falls. Keep out of the way of the fairing limb.
•Pruning Cut - Cut the limb stump flush at the edge of
