CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log size.
W ARNING:
Do notstandon thelog
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 of wood could be flung toward opera-
tor .
S
Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting andnev erholdthe logwith yourleg
or foot.
S
Do not cut in an area where logs, limbs,
and roots are tangled such as in a blown
down area. Dragthe logs intoa clear area
before cutting by pulling out exposed and
cleared logs first.
