BUCKING WITH A WEDGE
(See Figure 16)
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.
BUCKING LOGS UNDER STRESS
(See Figure 17)
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.
OVERBUCKING
(See Figure 18)
Begin on the top side of the log with the bottom of the saw against the log; exert light pressure
downward. Note that the saw will tend to pull away from you.
UNDERBUCKING
(See Figure 19)
Begin on the under side of the log with the top of the saw against the log; exert light pressure
upward. During underbucking, the saw will tend to push back at you. Be prepared for this
reaction, and hold the saw firmly to maintain control.
