5. Bucking a Log
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 as illustrated in Figure 6, it is cut from the top (overbuck).
When the log is supported on one end, as illustrated in Figure 7, cut 1/3 the diameter from the underside
(underbuck). Then make the finished cut by over bucking to meet the first cut. When the log is supported on both
ends, as illustrated in Figure 8, cut 1/3 of that diameter from the top over buck. 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,
as illustrated in Figure 9. When "cutting through", to maintain complete control release the cutting pressure near the
end of the cut without relaxing your grip on the chain saw handles. 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 motor before
moving from tree to tree.
