Bucking
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 (D). To avoid the danger, keep the Safe-T-
Tip® anti-kickback device attached while cutting.

(G) FINISHING CUT
• During bucking operations always stand on the uphill side so
that the cut-off section of the log can not roll over you.
• Sometimes it is impossible to avoid pinching (with just stan-
dard cutting techniques) or difficult to predict which way a log
will settle when cut. To avoid pinching while cutting, review the
following sections, Bucking with a Wedge and Logs Under
Stress.
Give special attention to logs under stress to prevent the bar and
chain from pinching.

Logs Under Stress
• Make the first bucking cut (F) 1/3 of the way through the log and
finish with a 2/3 cut (G) on the opposite side. As the log is being
cut, it will tend to bend. The saw can become pinched or hung
in the log if you make the first cut deeper than 1/3 of the
diameter of the log.

NOTE:
When bucking or felling with a wedge, it may be necessary to
remove the Safe-T-Tip® anti-kickback device to allow the bar
to be drawn through the cut. After the cut is complete, the tip
should be replaced immediately.
D
Bucking with a Wedge
If the wood diameter is large enough for you to insert a soft
bucking wedge (E) without touching the chain, you should use the
wedge to hold the cut open to prevent pinching.
Buttress Roots
A buttress root is a large root extending from the trunk of the tree
above ground. Large buttress roots should be removed prior to
felling. Make the vertical cut (A) into the buttress first, followed
by the horizontal cut (B). Remove the resulting loose section (C)
from the work area. Utilize the proper instructions from the
Operation-Tree Felling section of the manual after the large
buttress roots have been removed.
