Overcutting Undercutting
Undercutting involves cutting on the under-
side of the log with top of saw against the log.
When undercutting 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 of the log. The compression side of
the log is where the pressure of the log’s
weight is concentrated.

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

LIMBING AND PRUNING
WARNING:
Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branches or ob-
jects at the nose of the guide bar when limb-
ing or pruning. Allowing such contact can re-
sult in serious injury.
WARNING:
Never climb into a tree
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
S
Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure foot-
ing and balance.
S
Watch out for springpoles. Use extreme
caution when cutting small size limbs.
Slender material may catch the saw chain
and be whipped toward you or pull you off
balance.
S
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.
S
Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
S
Always limb a tree after it is cut down. Only
then can limbing be done safely and prop-
erly.
S
Leave the larger limbs underneath the
felled tree to support the tree as you work.
