Common Cutting Techniques
Limbing
Removing the branches from a fallen tree. When limbing, leave
larger lower limbs to support the log off the ground. Remove
the small limbs in one cut. Branches under tension should be
cut from the bottom of the branch towards the top to avoid
binding the pruner as shown below. Trim limbs from opposite
side keeping tree stem between you and pruner. Never make
cuts with pruner between your legs or straddle the limb to
be cut.
