Bucking a Log (continued)
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
