OPERATION
BUCKING WITH A WEDGE (See Fig. 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 Fig. 17)
Make the rst bucking cut 1/3 of the way through the log, and nish 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 rst 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 Fig. 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 Fig. 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 rmly to maintain control.
