Felling back cut
1. Make the felling back cut (Fig. 31, A) at least 50 mm higher than the horizontal
notching cut (Fig. 31). Keep the felling back cut parallel to the horizontal notching
cut. Make the felling back cut so enough wood is left to act as a hinge. The hinge
(Fig. 31, C) wood keeps the tree from twisting and falling in the wrong direction. Do
not cut through the hinge.
2. As the felling gets close to the hinge, the tree should begin to fall. If there is any
chance that the tree may not fall in desired direction or it may rock back and bind
the saw chain, stop cutting before the felling back cut is complete and use wedges
of wood, plastic or aluminium to open the cut and drop the tree along the desired
line of fall.
3. When the tree begins to fall remove the product from the cut, stop the engine, put
the product down, then use the retreat path planned. Be alert for overhead limbs
falling and watch your footing.
Limbing and pruning
Limbing is 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 (Fig. 32).
Branches under tension should be cut from the bottom up to avoid binding the product.

WARNING!
Never climb into a tree to limb or prune! Do not stand on ladders,
platforms, logs, or in any position which may cause you to lose the balance or
control of the saw! When pruning trees, it is important not to make the flush cut
next to main limp or trunk until you have cut off the limb further out to reduce
the weight! This prevents stripping the bark from the main member!
WARNING!
If the limbs to be pruned are above chest height, hire a professional
to perform the pruning!
