OPERATION ■n When bucking on a slope, always stand on the uphill side of the log. To maintain complete control of the chain saw when cutting through the log, release the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Do not 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. BUCKING WITH A WEDGE See Figure 19. If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching. NOTE: When bucking or felling with a wedge, you may need to remove the SAFE-T-TIP anti-kickback device to allow the bar to be drawn through the cut. After you complete the cut, reinstall the tip. BUCKING LOGS UNDER STRESS See Figure 20. Make the first bucking cut 1/3 of the way through the log and finish with a 2/3 cut on the opposite side. As you cut the log, it will tend to bend. The saw can become pinched or hung in the log if you make the first cut deeper than 1/3 of the diameter of the log. Give special attention to logs under stress to prevent the bar and chain from pinching. OVERBUCKING See Figure 21. Begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. Note that the saw will tend to pull away from you.

OPERATION
When bucking on a slope, always stand on the
uphill side of the log. To maintain complete
control of the chain saw when cutting through
the log, release the cutting pressure near the
end of the cut without relaxing your grip on the
chain saw handles. Do not 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.
BUCKING WITH A WEDGE
See Figure 19.
If the wood diameter is large enough for you to
insert a soft bucking wedge without touching the
chain, you should use the wedge to hold the cut
open to prevent pinching.
NOTE:
When bucking or felling with a wedge, you
may need to remove the SAFE-T-TIP anti-kickback
device to allow the bar to be drawn through the
cut. After you complete the cut, reinstall the tip.
BUCKING LOGS UNDER STRESS
See Figure 20.
Make the first bucking cut 1/3 of the way through
the log and finish with a 2/3 cut on the opposite
side. As you cut the log, it will tend to bend. The
saw can become pinched or hung in the log if you
make the first cut deeper than 1/3 of the diameter
of the log.
Give special attention to logs under stress to
prevent the bar and chain from pinching.
OVERBUCKING
See Figure 21.
Begin on the top side of the log with the bottom
of the saw against the log; exert light pressure
downward. Note that the saw will tend to pull
away from you.
