When the log is supported on one end, as 
illustrated in Figure 5, cut 1/3 the diameter 
from the underside (underbuck) (1). Then 
make the finished cut by overbucking (2) to 
meet the first cut.
When the log is supported on both ends, as 
illustrated in Figure 6, cut 1/3 the diameter 
from the top (overbuck) (1). Then make the 
finished cut by underbucking (2) 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 6. 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.
