Overcutting Undercutting
Undercutting involves cutting on the under-
side of the log with top of saw against the log.
When undercutth_g use light upward pres-
sure. Hold saw firmly and maintain control
The saw will tend to push back toward you.
_.WARNING: Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
Always make your first cut on the compres-
sion side ofthe tog. The compression sMe 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 second
overout.
• Watch for logs with a compression side to
prevent the saw from pinching. See illustra-
tion for cutting logs with a compression side.
BUCKING USING A LOG OR
SUPPORT STAND
• Remember your first cut is always on the
compressions side ofthe log. (Refer tothe

LIMBING AND PRUNING
_L, WARNING:
Be aiert for and guard
against kickback. Do not allow the moving
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.
_,WARNING:
Never climb into atree
to limb or prune. Do not stand on ladders,
platforms, a log. or in any position which can
cause you to lose your balance or control of
the saw.
IMPORTANT POINTS
• Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure foot-
ing and balance.
• Watch out for springpotes. Springpoles
are small size limbs which can catch the
saw chain and whip toward you or pull you
off balance. Use extreme caution when
cutting small size limbs.
• Be alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or the
saw when the tension in the wood fibers is
released.
• Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
• Always limbatreeafter itis cutdown. Only
then can limbing be done safely and prop-
erly.
• 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.
