OPERATION
DO NOT cut down a partially fallen tree with your saw.
Be extremely cautious with partially fallen trees that may be
poorly supported. When a tree doesn't fall completely, set the
saw aside and pull down the tree with a cable winch, block and
tackle, or tractor.
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 horizontal cut (A, Fig. 61) into the buttress first,
61
followed by the vertical 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.

Bucking

Bucking is the term used for cutting a fallen tree to the desired
log length.
• Cut only one log at a time.
WARNING: Support small logs on a saw horse or
another log while bucking. Never allow another
person to hold the log while cutting and never hold
the log with your leg or foot.
62
WARNING: 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,
Fig. 62).
WARNING: During bucking operations always stand
on the uphill side so that the cut-off section of the
log can not roll over you.
WARNING: If saw becomes pinched or hung in a log,
63
don't try to force it out. You can lose control of the
saw resulting in injury and/or damage to the saw.
Stop the saw, drive a wedge of plastic or wood into
the cut until the saw can be removed easily (E, Fig.
63). Restart the saw and carefully reenter the cut. Do
not attempt to restart your saw when it is pinched or
hung in a log.
WARNING: Do not stand on the log being cut. Any
portion can roll causing loss of footing and control.
Do not cut in an area where logs, limbs, and roots are
tangled. Drag the logs into a clear area before cutting
by pulling out exposed and cleared logs first.
Bucking with a Wedge
If the wood diameter is large enough for you to insert a soft
bucking wedge (E, Fig. 63) without touching the chain, you
should use the wedge to hold the cut open to prevent pinching.
