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.
Drive a wedge (Z) into the horizontal cut to
make the tree fall.
When the tree begins to fall, leave the danger ar-
ea via the retreat path planned. Be alert for over-
head limbs falling and watch your footing.
Limbing a Tree (see figure K)
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 the figure.
Branches under tension should be cut from the
bottom up to avoid binding the chain saw.
Bucking a Log (see figures L – O)
Bucking is cutting a log into lengths. It is impor-
tant to make sure your footing is firm and your
weight is evenly distributed on both feet. When
possible, the log should be raised and support-
ed by the use of limbs, logs or chocks. Follow
the simple directions for easy cutting.
Troubleshooting
The following chart lists problem symptoms, possible causes and corrective action, if your machine

When the log is supported along its entire
length, it is cut from the top (overbuck).
When the log is supported on one end, 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, 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. When "cutting through",
release the cutting pressure near the end of the
cut without relaxing your grip on the chain saw
handles in order to maintain complete control.
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 chain saw motor before moving from
tree to tree.
