LIMBING AND PRUNING
WARNING: Be atert 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.
A_, 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 slow_y, keeping both hands firmly
gripped on the saw. Maintain secure foot-
ing and balance.
• 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.
• 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.
• 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. Undercutting could
cause limbs to fall and pinch the saw.
PRUNING
_L, 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 (2 to 5 cm) collar from the truck
of the tree.
