Bucking a Log (see figures K–N)
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, 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.
