9.9.3 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 middle, make a downward cut halfway through the log and then make the undercut.
This will prevent the log from pinching the bar and chain. Be 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.
Fig 13a
 Log supported along entire length: Cut from top
(overbuck), being careful to avoid cutting into
the ground (Fig. 13a).
Fig 13b
 Log supported on 1 end: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid
splintering. Second, cut from above (overbuck)
to meet first cut and avoid pinching (Fig. 13b).
Fig 13c
 Log supported on both ends: First, overbuck 1/3
diameter of log to avoid splintering. Second,
underbuck to meet first cut and avoid pinching
(Fig. 13c)
NOTE: The best way to hold a log while bucking is to use a sawhorse. When
this is not possible, the log should be raised and supported by the limb
stumps or by using supporting logs. Be sure the log being cut is securely
supported.
9.9.4 Bucking using a sawhorse
fig 14
For personal safety and ease of cutting, the correct
position for vertical bucking is essential (fig. 14).
Vertical cutting:
 Hold the saw firmly with both hands and keep
the saw to the right of your body while cutting.
 Keep the left arm as straight as possible.
 Keep weight on both feet.
Caution: while the saw is cutting, be sure the chain and bar are being
properly lubricated.
