REMOVING BUTTRESS ROOTS
See Figure 16.
A buttress root is a large root extending from the
trunk of the tree above the ground. Remove large
buttress roots prior to felling. Make the horizontal
cut into the buttress first, followed by the vertical
cut. Remove the resulting loose section from the
work area. Follow the correct tree felling procedure
as stated in Felling Trees after you have removed
the large buttress roots.
BUCKING
See Figures 17 - 20.
Bucking is the term used for cutting a fallen tree
to the desired log length.

Always make sure your footing is secure and
your weight is distributed evenly on both feet.
■

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.
Refer to Kickback earlier in this manual.
■

When bucking on a slope, always stand on the
uphill side of the log. To maintain complete con-
trol 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.
