OPERATION
BUCKING LOGS UNDER STRESS
See Figures 20 and 21.
When the log is supported along its entire length, it
should be cut from the top or overbucking.
When the log is supported on one end, cut 1/3 the
diameter from the underside or underbucking. Then
make the finishing cut by overbucking to meet the first
cut.
As the log is being cut, it will tend to bend. The saw
can become pinched or hung in the log if you make the
first cut deeper than 1/3 of the diameter of the log.
Give special attention to logs under stress to prevent
the bar and chain from pinching.
When bucking on a slope, always stand on the uphill
side of the log as shown in Figure 19. When “cutting
through”, to maintain complete control of the chain
saw, release the cutting pressure near the end of the
cut without relaxing your grip on the chain saw
handles. Do not let the chain contact the ground. After
completing the cut, wait for the saw chain to stop
before your move the chain saw. Always stop the
motor before moving from tree to tree.
See Figure 19.

■ Sometimes it is impossible to avoid pinching (with
just standard cutting techniques) or difficult to predict
which way a log will settle when cut. To avoid
pinching while cutting, rotate or move the log so that
the pinch is eliminated.
