Bucking/Limbing - Shindaiwa 488EMC Owner's/Operator's Manual

Bucking
Techniques
If the log is well supported, start
your cut from the top of the log.
Keeping the guide bar parallel to
the ground, cut straight down but
do not allow the saw to cut into
the ground.
Cutting downed timber, or "buck-
ing," increases the possibility of
the wood settling and pinching
the guide bar. Driving one or more
soft plastic or wooden bucking
wedges can help prevent bar-
pinching during a cut.
Use two cuts when bucking near
the inboard end of an unsup-
ported log.
1. Make the first cut as an overbuck
approx. 1/3 the diameter of the
log.
2. Finish the job with an underbuck
coming up from beneath and
joining the first cut.

WARNING!
Always cut downed timber from the
uphill side of the wood! Be alert for
potential injury from rolling or shifting
logs! Downed timber may shift or roll
unpredictably during cutting or
handling operations!
Use two cuts when bucking the
outboard end of an unsupported
log. Your first cut should be an
underbuck, cutting upward
through approximately 1/3 the
diameter of the tree. Finally, move
to the top of the log and finish the
cut by bucking down
(overbucking) to your first cut.

About 1/3 of Tree Diameter
Limbing
Limbing a standing tree is usually
accomplished in the same manner as
bucking, with a third and final cut
used to remove the remaining stub of
the limb.

WARNING!
Kickback danger increases in over-
height or out of position cutting! Do
not overreach, or attempt to cut
above shoulder height!
NOTE:
When cutting unsupported logs or limbs,
starting with an underbuck cut will minimize
the possibility of the wood splitting during
the bucking cut.
