BUCKING A LOG
CAUTION: BUCKING LOGS UNDER
TENSION INCREASES THE CHANCE OF
KICKBACK. Use one of the methods below
to support the log when bucking.
Bucking is cutting a log into lengths . It
is important to make sure footing is firm
and weight is evenly distributed on both
feet . When possible, the log should be
raised and supported by the use of limbs,
logs or chocks .
• When the log is supported along its
entire length, cut from the top
(overbuck) (Fig . 37) .

• When the log is supported on one end,
cut 1/3 the diameter from the underside
(underbuck), then make the finished cut
by overbucking to meet the first cut
(Fig . 38) .

• To maintain complete control when
cutting through, release the cutting
pressure near the end of the cut without
relaxing the grip on the chain saw
handles .
• Don't let the chain contact the ground .
• After completing the cut, wait for the
saw chain to stop before you move the
chain saw .
• Always stop the motor before moving
from tree to tree .
