drawn through the cut. After the cut is complete,
the tip should be reinstalled immediately.
 As tree starts to fall, stop the chain saw and put
it down immediately. Retreat along the cleared
path, but watch the action in case something
falls your way. Be alert for overhead limbs or
branches that may fall and watch your footing.
WARNING:
Never cut through to the notch when making a
backcut. The hinge controls the fall of the tree,
this is the section of wood between the notch
and backcut.
BUCKING
See Figure 26.
Bucking is the term used for cutting a fallen tree
to the desired log length.
 Cut only one log at a time.
 Support small logs on a saw horse or another
log while bucking.
 Keep a clear cutting area. Make sure that no
objects can contact the guide bar nose and
chain during cutting, this can cause kickback.
To avoid the danger, keep the SAFE-T-TIP
anti-kickback device attached while cutting.
Refer to Kickback in the Specific Safety Rules
section of this manual for more information.
 W hen 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.
OPERATION
®
BUCKING WITH A WEDGE
See Figure 27.
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
device to allow the bar to be drawn through the
cut. After you complete the cut, reinstall the tip.
