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-
log 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
• Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure foot-
ing and balance.
• Watch out for springpoles. 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 limb a tree after it is cut down. Only
then can Iimbing 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.
• Keep the tree between you and the chain.
Cut from the side of the tree opposite the
branch you are cutting.
• Remove larger, supporting branches with
the cutting techniques described in BUCK-
ING WITHOUT A SUPPORT.
• Always use an overcut to cut small and
freely hanging limbs. Undercuttiog could
cause limbs to fall and pinch the saw.
PRUNING
WARNING:
Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder. Get
a professional to do the job.
• Make your fist cut 1/3 of the way
through the bottom of the limb.
• Next make a 2nd cut all the way
through the limb. Then cut a third
overcut leaving a 1 to 2 inch collar from
the truck of the tree.
