 Do not cut above chest height, as a saw held
higher is difficult to control against kickback
forces.
 Cut only when visibility and light are adequate
for you to see clearly.
BUCKING
See Figures 13 - 15.
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.
 When bucking on a slope, always stand on
the uphill side of the log. To maintain complete
control of the chainsaw when cutting through
the log, release the cutting pressure near the
end of the cut without relaxing your grip on the
chainsaw handles. Do not let the chain 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.
 Sometimes it is impossible to avoid pinching
(with just standard cutting techniques) or difficult
to predict which way a log will settle when cut.
To avoid pinching while cutting, rotate or move
the log so that the pinch is eliminated.
