REMOVING BUTTRESS ROOTS
A buttress root is a large root extending from the trunk of
the tree above the ground. Remove large buttress roots
before 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 after you have removed the large buttress
roots. Refer to “Operation – Proper Procedure for Felling
Trees” earlier in this manual.
BUCKING
Bucking is the term used for cutting a fallen tree to the
desired log length.

Q Support small logs on a saw horse or another log
while bucking.

QQ
Q Keep a clear cutting area. Make sure no objects can
contact the guide bar nose and chain during cutting;
this can cause kick-back. To avoid the danger, keep the
SAFE-T-TIP
®
anti-kick-back device attached while cutting.
Refer to “Safety – Kick-back” earlier in this manual.

Q During bucking operations, stand on the uphill side so
that the cut-off section of the log cannot roll over you.

Q Sometimes it is impossible to avoid pinching with just
standard cutting techniques, or difficult to predict which
way a log will settle when cut.
BUCKING WITH A WEDGE
If the wood diameter is large enough for you to insert a soft
bucking wedge without touching the chain, 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-kick-back device to
allow the bar to be drawn through the cut. After you
complete the job, reinstall the tip.
