OPERATION
 On large diameter trees, stop the back cut
before it is deep enough for the tree to either
fall or settle back on the stump. Then insert
soft wooden or plastic wedges into the cut so
they do not touch the chain. The wedges can
be driven in, little by little, to help jack the tree
over. See Figure 16.
 As tree starts to fall, stop the chain saw and put
it down immediately. Retreat along the cleared
path, but watch the action in case something
falls your way. Be alert for overhead limbs or
branches that may fall and watch your footing.
WARNING:
Never cut through to the notch when making a
backcut. The hinge controls the fall of the tree,
this is the section of wood between the notch
and backcut.
BUCKING
See Figures 17 - 20.
Bucking is the term used for cutting a fallen tree to
the desired log length.
 Always make sure your footing is secure and your
weight is distributed evenly on both feet.
 Cut only one log at a time.
 Support small logs on a saw horse or another log
while bucking.

FINISHING CUT
LOG SUPPORTED AT BOTH ENDS:
 Keep a clear cutting area. Make sure that no ob-
jects can contact the guide bar nose and chain
during cutting, this can cause kickback.
 When bucking on a slope, always stand on the
uphill side of the log. To maintain complete control
of the chain saw when cutting through the log,
release the cutting pressure near the end of the
cut without relaxing your grip on the chain saw
handles. Do not 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.
 Sometimes it is impossible to avoid pinching (with
just standard cutting techniques) or difficult to
predict which way a log will settle when cut. To
avoid pinching while cutting, rotate or move the
log so that the pinch is eliminated.
BUCKING LOGS UNDER STRESS
See Figures 19 - 20.
When the log is supported along its entire length, it
should be cut from the top or overbucking.
When the log is supported on one end, cut 1/3 the
diameter from the underside or underbucking. Then
make the finishing cut by overbucking to meet the
first cut.
