OPERATING INSTRUCTIONS
Bucking
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 cut-
ting as 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 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
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.
Bucking logs under stress
When the log is supported on one end, cut 1/3 the
diameter from the underside. Then make the nished
cut by overbucking to meet the rst cut. When the log
is supported on both ends, cut 1/3 of the diameter from
the top overback. Then make the nished cut by under
bucking the lower 2/3 to meet the rst cut.
