5-3. LIMBING
Limbing a tree is the process of remov­
ing the branches from a fallen tree. Do
not remove supporting limbs (A) until
after the log is buckecf (cut) into lengths
(Figure 5-3A).
Branches under tension should be cut
from the bottom up to avoid binding the
chain saw.
WARNING
Never cut tree limbs while standing on
tree trunk.

5-4. BUCKING
Bucking is cutting a fallen log into
lengths. Make sure you have a good
footing and stand uphill of the log when
cutting on sloping ground. If possible,
the log should be supported so that the
end to be cut off is not resting on the
ground. If the log is supported at both
ends and you must cut in the middfe,
make a downward cut halfway through
the log and then make the undercut,
This will prevent the iog from pinching
the bar and chain.8e careful that the
chain does not cut into the ground when
bucking as this causes rapid dulling of
the chain.
When bucking on a slope, always stand
on the uphill side,
1. Log supported along entire iength:
Cut from top (overbuck), being
careful to avoid cutting into the
ground (Figure 5-4A).
2. Log supported on 1 end: First, cut
from bottom (underbuck) 1/3 diamet­
er of log to avoid splintering.
Second, cut from above (overbuck)
to meet first cut and avoid pinching
(Figure 5-4B).
3. Log supported on both ends: First,
overbuck 1/3 diameter of tog to
avoid splintering.Second, underbuck
to meet first cut and avoid pinching
(Figure 5-4C).
NOTE: The best way to hold a log whiie
bucking is to use a sawhorse. When
this is not possible, the log should be
raised and supported by the limb stum­
ps or by using supporting logs. Be sure
the log being cut is securely suppored.

5-5. BUCKING USING A
SAWHORSE
For persona! safety and ease of cutting,
the correct position for vertical bucking
is essential (Figure 5-5A),
VERTICAL CUTTING:
A. Hold the saw firmly with both hands
and keep the saw to the right of your
body while cutting.
B. Keep the left arm as straight as
possible.
C. Keep weight on both feet.
CAUTION
While the saw is cutting, be sure the
chain and bar are being properly
lubricated.
