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 pre
-
vent 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.
1. Log supported along entire length: Cut from top (overbuck), being careful to
avoid cutting into the ground (Fig. 4A).
2. Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of
log to avoid splintering. Second, cut from above (over buck) to meet first cut and
avoid pinching (Fig. 4B).
3. Log supported on both ends: First, over buck 1/3 diameter of log to avoid
splintering. Second, underbuck to meet first cut and avoid pinching (Fig. 4C).
4. When bucking on a slope always stand on the uphill side of the log, as illu-
strated in Fig. 4D. When “cutting through”, to maintain complete control release
the cutting pressure near the end of the cut without relaxing your 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.
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.
BUCKING USING A SAWHORSE
For personal safety and ease of cutting, the correct
position for vertical bucking is essential (Fig. 5).
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.
