BUCKING LOGS UNDER STRESS
See Figure 24.
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 pre-
vent the bar and chain from pinching.
OVERBUCKING
See Figure 25.
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 26.
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.
WARNING:
Never climb into a tree to limb or prune. Do not
stand on ladders, platforms, a log, or in any
position which can cause you to lose your bal-
ance or control of the saw and cause death or
serious personal injury.
