When the log is supported on both ends, as illustrated in Figure M, 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.

Figure M: Log Supported Both Ends
When bucking on a slope always stand on the
uphill side of the log, as illustrated in Figure N.
When “cutting through”, to maintain complete
control release the cutting pressure near the
end of the cut without relaxing your grip on
the chainsaw handles. Don’t let the chain
contact the ground. After completing the
cut, wait for the saw chain to stop before
you move the chainsaw. Always stop the
motor before moving from tree to tree.
Stand on uphill side when cutting
because log may roll
