NOTE: Before felling cut is complete, use
wedges to open the cut if necessary to
controlthedirectionoffall. Toavoidkickback
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 fell-
ing cut, or movement in the upper
branches.
S As treestarts to fall,stop saw,put it down,
and get away quickly on your planned re-
treat path.
S DO NOT cut down a partially fallen tree
withyour saw. Beextremely cautiouswith
partially fallen trees that may be poorly
supported. When a tree doesn’t fall com-
pletely,setthesawasideandpulldownthe
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 footing andcontrol. 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 of wood could beflung towardopera-
tor .
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cuttingandnever holdthelogwith yourleg
or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled such as in a blown
downarea. Dragthe logsintoa cleararea
before cutting by pulling out exposed and
cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
WARNING: Ifsaw becomespinched
or hung ina log, don’t try to force it out. You
can losecontrol ofthesaw resulting ininjury
and/or damage to the saw. Stop the saw,
drive awedge of plastic or wood into thecut
untilthesawcanberemovedeasily. Restart
the saw and carefully reenter the cut. To
avoid kickback and chain damage, do not
useametalwedge. Donotattempttorestart
your saw when itis pinched or hungin alog.
Use a wedge to remove pinched saw
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins o n the top side of the log
with the bottom of the saw against the log.
When overcutting use light downward pres-
sure .
