OPERATING INSTRUCTIONS
• When the log is supported on only one end,
cut 1/3 the diameter from the underside
(underbucking). Then make the nishing cut by
overbucking to meet the rst cut (Fig. 10d).
• When the log is supported on both ends, cut 1/3
of that diameter from the top overbuck. Then
make the nished cut by underbucking the lower
2/3 to meet the rst cut (Fig. 10e).
• When bucking on a slope, always stand on the
uphill side of the log (Fig. 10f).
• To maintain complete control when cutting
through, release the cutting pressure near the
end of the cut without relaxing the grip on the
chainsaw handles. Don’t allow the chain to
contact the ground. After completing the cut, wait
for the saw chain to stop before you move the
chainsaw. Always stop the motor before moving
from tree to tree.
