CUTTING A FAL LEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log size.
WARNING: Do notstand onthe 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 ofwoodcouldbe flungtowardoper-
ator.
S Use a sawhorse to cut small logs. N ever
allow another person to hold the log while
cutting andnever holdthe logwith 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.
