Undercutting involves cutting on the
underside of the log with top of saw
against the log. When undercutting use
light upward pressure. 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
controlled in this position.
Always make your first cut on the com-
pression side of the log. The compres-
sion side of the log is where the pressure
of the log's weight is concentrated.

LIMBING AND PRUNING
_ WARNING: 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.
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 springpoles. 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 springback 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.
