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 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.
BB.104 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 illustrated in
Figure BB.103. Branches under tension should be cut from the bottom up to avoid binding the
chain saw.
BB.105 Bucking a log
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 BB.104, it is cut from
the top (overbuck).
When the log is supported on one end, as illustrated in Figure BB.105, cut 1/3 the diameter
from the underside (underbuck). Then make the finished cut by overbucking to meet the first
cut.
When the log is supported on both ends, as illustrated in Figure BB.106, cut 1/3 the diameter
from the top (overbuck). Then make the finished cut by underbucking the lower 2/3 to meet the
first cut.
When bucking on a slope always stand on the uphill side of the log, as illustrated in Figure
BB.107. When "cutting through", to maintain complete control release the cutting pressure near
the end of the cut without relaxing your grip on the chain saw handles. Don't let the chain
contact the ground. After completing the cut, wait for the saw chain to stop before you move the
chain saw. Always stop the motor before moving from tree to tree.
