Follow the correct tree felling procedure after you have removed the large buttress
roots.
BUCKING
See Figure 28.
Bucking is the term used for cutting a felled tree to the desired log length.
Cut only one log at a time.
Support small logs on a saw horse or another log while bucking.
Keep a clear cutting area. Make sure that no objects can contact the guide bar nose
and chain during cutting; this can cause kickback.
During bucking operations, stand on the uphill side so that the cut-off section of the
log cannot roll over you.
Sometimes it is impossible to avoid pinching (with just standard cutting techniques)
or difficult to predict which way a log will settle when cut.
1.
BUCKING WITH A WEDGE
See Figure 29.
If the wood diameter is large enough for you to insert a soft bucking wedge without
touching the chain, you should use the wedge to hold the cut open to prevent pinching.
2.
BUCKING LOGS UNDER STRESS
See Figure 30.
Make the first bucking cut 1/3 of the way through the log and finish with a 2/3 cut on
the opposite side. As you cut the log, 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.
3.
OVERBUCKING
See Figure 31.
Begin on the top side of the log with the bottom of the saw against the log; exert light
downward pressure. Note that the saw will tend to pull away from you.
4.
UNDERBUCKING
See Figure 32.
Begin on the underside of the log with the top of the saw against the log; exert light
upward pressure. During underbucking, the saw will tend to push back at you. Be
prepared for this reaction and hold the saw firmly to maintain control.
