• BUCKING
Bucking is cutting a fallen log into lengths. When cutting on
sloping ground, make sure you have good footing and that you
stand uphill from the log. 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 then make the undercut.
This will prevent the log from pinching the bar and chain. Take
care 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 the top
(overbuck), being careful to avoid cutting into the ground (Fig. 4A).
2. Log supported at one end: First, cut from the bottom
(underbuck) through 1/3 of the diameter of the log to avoid
splintering. Second, cut from above (overbuck) to meet the first
cut and avoid pinching (Fig. 4B).
3. Log supported at both ends: First, overbuck through 1/3 of the
diameter of the log to avoid splintering. Second, underbuck to
meet the first cut and avoid pinching (Fig. 4C).
4. When bucking on a slope, always stand on the uphill side of
the log, as illustrated in Fig. 4D. When 'cutting through', release
the cutting pressure near the end of the cut without relaxing your
grip on the chainsaw handles to help you maintain complete
control. Don't let the chain come into contact with the ground.
After completing the cut, wait for the saw chain to stop before
moving the chainsaw. Always stop the motor before moving from
tree to tree.
