Bucking/Limbing - Shindaiwa 300S 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 unsupported
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 unpredict-
ably 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.
Second Cut (overbuck)
First Cut (underbuck)
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.
