OPERATING INSTRUCTIONS
Felling Back Cut
a. Make the felling back cut at least 2 inches (50.8 mm) higher than the horizontal notching
cut (Fig. 8b). Keep the felling back cut parallel to the horizontal notching cut. Make the
felling back cut so that 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.
b. As the felling cut gets close to the hinge, the tree should begin to fall. If there is any chance
that the tree may not fall in the 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 aluminum to open the cut and drop the tree along the desired line of fall.
c. When the tree begins to fall, remove the chainsaw from the cut, stop the motor, put the
chainsaw down, then use the retreat path planned. Be alert for overhead limbs falling and
watch your footing.
9. Limbing
Limbing is removing branches from a fallen tree.
When limbing, leave larger limbs to support the
log off the ground. Remove the small limbs in one
cut as illustrated in Fig. 9. Branches under tension
should be cut from the bottom up to avoid binding
the chainsaw.
WARNING
• There is an extreme danger of kickback during
the limbing operation. Be extremely cautious and
avoid contacting the log or other limbs with the
tip of the guide bar.
