3. Felling back cut
Make the felling back cut (Y) at least 50 mm
higher than the horizontal notching cut as
illustrated in Figure I. 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 wood keeps the
tree from twisting and falling in the wrong
direction. Do not cut through the hinge.
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 (Z) to open the cut and drop the
tree along the desired line of fall (
When the tree begins to fall remove the chain
saw from the cut, stop the motor, put the
chain saw down, then use the retreat path
planned ( ). Be alert for overhead limbs

falling and watch your footing.

4. Limbing a tree
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 as
Fig.3
illustrated in Figure 3. Branches under tension
should be cut from the bottom up to avoid
binding the chain saw.

5. Bucking a log
Fig.3
Bucking is cutting a log into lengths. It is
important to make sure your footing is firm
and your weight is evenly distributed on both
feet. When possible, the log should be raised
and supported by the use of limbs, logs or
chocks. Follow the simple directions for easy
cutting.
When the log is supported along its entire
length as illustrated in Figure 4, it is cut from
the top (overbuck) , avoid contacting ground
as this will greatly reduce the chain sharpness.

When the log is supported on one end, as

illustrated in Figure 5, cut 1/3 the diameter from
the underside (underbuck)(1). Then make the
finished cut by overbucking(2) to meet the first cut.
