Hinge
S After removing the cutout of wood, make
the felling cut on the opposite side of the
notch. This is done by making a cut about
two inches higher than the center of the
notch. This will leave enough uncut wood
between the felling cut and the notch to
form a hinge. This hinge will help prevent
the tree from falling in the wrong direction.

NOTE
: Before felling cut is complete, use
wedges to open the cut when necessary to
control thedirectionof fall. 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:
crackin g soun ds, wid enin g of the felling cut,
or movement in the upper branches.
S A s tre e starts to fall, stop saw , put it down,
and get away quickly on your planned re-
treat path.
S DO NOT cu t down a p art ially fallen tr ee with
your saw . Be e xtremely cautious with par-
tially fallen trees that may be poorly sup-
ported. When a tree doesn’t fall completely,
set the saw aside and pull down the 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 length.
WARNING:
Do not stand on the log
being cut. Any portion can roll causing loss
of footing 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 ofwoodcould beflung towardoper-
ator.
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and never hold the log with your leg
or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a
clear area beforecutting by pulling outex-
posed and cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
WARNING:
If saw becomes pinched
or hung in a log, don’t try to force it out. You
can lose control of the saw resulting in injury
and/or damage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut
until the saw can be removed easily. Restart
the saw and carefully reenter the cut. Do not
attemptto restartyour saw whenit is pinched
or hung in a log.
Turn saw
OFF
and use a plastic or
wooden wedge to force cut open.
Use a wedge to remove pinched saw
Overcuttingbegins on the top side of thelog
with the saw against the log. When overcut-
ting use light downward pressure.
Overcutting Undercutting
Undercuttinginvolves cutting on the under-
side of the log with top of saw against thelog.
When undercutting use light upward pres-
sure. Hold saw firmly and maintain control.
The saw will tend to push back toward you.
WARNING:
Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
Always make your first cut on the compres-
sion side of the log. Thecompression sideof
the log is where the pressure of the log’s
weight is concentrated.
