BUCKING
Bucking is cutting a fallen log into lengths. Make sure that 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 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.
Note:
The best way to hold a log while bucking is to use a saw horse. When this is not
possible, the log should be raised and supported by limb stumps or by using supporting
logs. Be sure the log being cut is securely supported.

1. Log supported along entire length: cut from bottom(underbuck),being careful to avoid
cutting into the ground (Fig.8)
2. Log supported on 1 end proceed as if using a saw-horse: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck)
to meet first cut avoid pinching
3. 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. 9).
BUCKING USING A SAWHORSE (Fig.10)
1. Hold the saw firmly with both hands and keep the saw to the right of your body while
cutting.
2. Keep the left arm as straight as possible.
3. Keep weight on both feet.
