■ When cutting smaller logs, make sure the log
is properly supported to reduce the risk of per‐
sonal injury from loss of control of the chain
saw or movement of the log. Small logs can
move when contacted by the teeth of the
chain:
► Place logs through "V-shaped" supports on
top of a sawhorse whenever possible.
► Never permit another person to hold the
log.
► Never stabilize the log with your leg or foot.
■ Failing to control the saw at the bottom of a
bucking cut can cause severe personal injury
or death.
► Prepare the saw to exit the bottom of the
cut by reducing the feed force you exert on
the saw.
► Cushion the weight of the saw so that the
bar and chain are not thrust downward into
your lower body and legs as the bar/chain
exits the cut.
When bucking:
► Position the bumper spike of the saw against
the log and use it as a fulcrum.
► Continually reposition the bumper spike while
pushing the guide bar completely through the
log.

Limbing
Limbing is removing the branches from a fallen
tree.
WARNING
■ To prevent a log from rolling while limbing:
► Start limbing by leaving the limbs on the
lower, downhill side of the log to hold the
log off the ground.
► Stabilize the log with sturdy wedges, shims
or chocks, if necessary.
► Never stand on a log while limbing it.
■ There is an increased danger of kickback dur‐
ing limbing operations, as limbs, leaves, stems
and other material can entangle (bind) the cut‐
ters of the chain in the upper quadrant of the

► If a pinch occurs that traps or holds the bar
