Overcutting Undercutting
Undercutting involves cutting on the um
derside of the log with top of saw against
the log, When undercutting use light up-
ward pressure. Hold saw firmly and main-
tain control The saw will tend to push
back toward you.
411_ W ARNING: Never turn saw upside
down to undercut. The saw cannot be
controlled in this position.
Always make your first cut on the com-
pressions side of the log, The compres-
sion side of the log is where the pressure
of the log's weight is concentrated,

BUCKING WITHOUT A SUPPORT
• Overcut through 1/3 of the diameter of
the log,
• Roll the log over and finish with a sec-
ond overcut.
• Watch for logs with a compression
side to prevent the saw from pinching.
See illustration above for cutting logs
with a compression side,
BUCKING USING A LOG OR
SUPPORT STAND
• Remember your first cut is always on
the compression side of the log,
(Refer to the illustration below for your
first and second cut)
• Your first cut should extend 1/3 of the
diameter of the log,
• Finish with your second cut.

LIMBING AND PRUNING

OWARNING: Be alert for and guard
against kickback. Do not allow the mov-
ing chain to contact any other branches
or objects at the nose of the guide bar
when limbing or pruning, Allowing such
contact can result in serious injury.
_1_ WARNING: Never climb into a tree
to limb or prune. Do not stand on lad-
ders, platforms, a log, or in any position
which can cause you to lose your bal-
ance or control of the saw.
IMPORTANT POINTS
• Watch out for spring poles. Spring
poles are small size limbs which can
whip toward you or pull you off bal-
ance. Use extreme caution when cut-
ting small size limbs.
• Be alert for spring back from any
branches that are bent or under pres-
sure. Avoid being struck by the branch
or the saw when the tension in the
wood fibers is released,
• Frequently clear branches out of the
way to avoid tripping over them.
LIMBING
• Limb a tree only after it is cut down,
• Leave the larger limbs underneath the
felled tree to support the tree as you
work.
• Start at the base of the felled tree and
work toward the top, cutting branches
and limbs. Remove small limbs with
one cut.
• Keep tree between you and the chain.
