NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to
controlthedirection offall. To avoidkickback
and chain damage, use wood or plastic
wedges, but never steel or iron wedges.
S Be alert to signs that the tree is ready to fall:
cracking sounds, widening of the felling cut,
or movement in the upper branches.
S As tree starts to fall, stop saw, put itdown,
and get away quickly on your planned re-
treat path.
S DO NOT cut down a partially fallen tree
with your saw. Be extremely cautious with
partially fallen trees that may be poorly
supported. When a tree doesn’t fall com-
pletely,setthesaw asideand pu lldownthe
tree with a cable winch, block and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log size.
WARNING: Do not stand on the log
being cut. Any portion can roll causing loss
of f ooting and control. Do not stand downhill
of the log being cut.
IMPORTANT POINTS
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
pieces ofwood could beflungtowardoper-
ator.
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and never hold thelog with your leg
or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled such as in a blown
down area. Drag the logs intoa clear area
before cutting by pulling out exposed and
cleared logs first.
